I'm a web developer but I don't really use image manipulation software much as most of the images are provided by designers so the Gimp tool is very unfamiliar to me. How to change a picture's PPI without changing the print size in GIMP, First order condition of log functions in general and interpretation. How to enlarge details or objects in photos using Gimp Simple yet very useful Gimp tutorial where we make a detail or an object in a Photo bigger and more visible by resizing it and adding a white rounded square frame around it. This means that the zoom level has an influence on everything. If I aim for a rectangle of certain size, it often becomes a challenge, because it's not easy to select a rectangle of certain size (in pixels) with the mouse. The other dimension of the highlight rectangle shall be that of the corresponding side handle. It is explicitly not desirable to do this during zooming, panning or actual bounding rectangle size change. If there is no selection then you can scale the layer without a floated selection being produced. The Height field shall be greyed-out when either fixed height or fixed size is enforced by the user. Can admitting previous illegal drug use without any criminal record bar you from entering Anglophone nations (US, UK, NZ, Canada, Australia)? We depend on bug #362915 to be fixed, then we can explore feasible solutions. I am a totally newbie gimp (using 2.6.11) user and whenever I need to select a rectangular area of an image (for further pasting it into a new image), I just click the "Rectangle Select Tool" button in the toolbar and try selecting with the mouse. Unless you are using a very old version of gimp, you can resize the selection box after selecting by placing your mouse over one of the selected rectangle's sides: You can also set the size and position manually from the tool There is a situation where clicking one of the icons shall directly change the orientation of a pending rectangle: if a rectangle is pending and the Fixed checkbox is checked and the mouse and the shift key are up and the textfield does not contain the string "Current" and the ratio (for fixed ratio) or the size (for fixed size) of the pending rect is exactly that what is displayed in the text box and a click on one of the icons causes the numerical values in textbox to be swappedthen the pending rectangle shall also be reoriented by swapping the width and height. This article demonstrates how to resize an image using GIMP. A 30x20 in-image rectangle can be displayed on screen as 300x200, and vice versa. Super User is a question and answer site for computer enthusiasts and power users. The Tool can also be called by clicking the tool icon: Tip. To resize an image with a freehand i.e., drag the corners of an image to resize it instead of entering a value for the new size, select the layer and tap the Shift+S keyboard shortcut. In ratio mode, '/' and ':' shall be treated as fully equivalent. Can the Dread Helm make all eyes glow red? Example: a 123x45 image rectangle is viewed at 1000%, only the left-most 2/3rd and top half of the rectangle is visible in the image window: 820x225 on-screen pixels go into the calculations ( 123*10*2/3 and 45*10/2). DownLoad Page > GIMP Script-Fu Shiro-Layer-To-Resize-Image *2. そうそう、断って置きます。 メニューでのスクリプトの場所は 画像(I) の下にしてありま … Press Ctrl + V to paste your selection then drag and drop it somwhere else (see picture). The other dimension of this rectangle shall be that of the corresponding side handle. I have edited the question and included the gimp version. This all makes the size of the side handles predictable (and thus faster to use each time) where it counts most (their smallest dimension) and uses their largest dimension to leave a gap to reach the corner handles from within. The pop-up list shall contain the items 'Aspect ratio', Width, Height, Size, in that order. All sizes in this spec are in on-screen pixels. Since 2005, BatchPhoto offers service to batch process images, edit and convert 170+ formats of images, but still … note that at any time the marching ants of a selection edge can obscure an inverted line. The interaction shall reflect this by showing the bounding rectangle in the newly calculated position; if the fixed height is greater than the actual canvas height, then the full height of the canvas shall be used; in ratio mode, the textfield shall accept the formats A/B and A:B, where A and B are two floating point numbers; in width and height modes, the textfield shall accept a single floating point number; in size mode, the textfield shall accept the formats A*B, AXB and AxB, where A and B are two floating point numbers. To learn more, see our tips on writing great answers. The only exception to this is that when resizing due to a cursor key press, the rubber-banding display shall be skipped. The rectangle cornered by the corner handles shall be the move handle: one big handle where users shall be able to move the bounding rectangle around the canvas by initiating a drag in this handle: the gray area shown here is purely for illustration in this spec and shall not be rendered in GIMP. The whole bounding rectangle area shall be one big move handle: When the sprite (mouse cursor) hovers over a corner handle, it shall highlight by inwardly doubling its perimeter line, and by hiding the other 3 corner handles: When the sprite hovers over a side handle, it shall highlight along the whole side of the bounding rectangle with a 1-pixel line, to communicate that it moves the side. It only takes a minute to sign up. To only change the size of one layer, select layer from side layer menu, then select the layer from top menu/ scale layer, type in number of pixels you want to change it to and save. You can hit the “Reset” button in the Scale tool dialogue box (red arrow in the image above) at any time to revert your selection area back to its original size. rev 2021.2.2.38474, The best answers are voted up and rise to the top, Super User works best with JavaScript enabled, By clicking “Accept all cookies”, you agree Stack Exchange can store cookies on your device and disclose information in accordance with our, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site, Learn more about Stack Overflow the company, Learn more about hiring developers or posting ads with us. In addition to the standard way to set the cursor, select a word or the whole sentence by means of single, double and triple click, the following shall apply: If the input focus is moved into the textfield by means of a single click, then the whole sentence in the textfield shall become selected. Pressing the shift key while rubber-banding shall toggle the checkbox in the other state. All keys can be individually assigned: File / Preferences / Interface / Hotkeys. Creation of a bounding rectangle usually starts with rubber-banding, and the handle size shall be the minimal handle size. Below is specified what happens in these cases: When one or more edges of the bounding rectangle is outside the canvas, then the canvas edge shall clip the effective selection. This includes a possible multi-word translation of "Current". Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Between being created and being committed (by means of a single mouse click in its area or the enter/return key), a rectangle is called to be in pending state. Between the 'Expand from centre' and Highlight checkbox there shall be the Fixed ratio/width/height/size control: It is a checkbox, with (new) a pop-up list in the first row, combined with a single textfield and two icons (portrait; landscape) in the second row. When either side of a corner handle, or the not-bounding-rectangle-aligned side of a side handle, is equal or greater that the corresponding side of the bounding rectangle, the handle shall not be displayed during rubber-banding. This page was last modified on 3 February 2008, at 19:19. Is it possible to learn how to sing properly without a teacher? This is to prevent accidental move when trying to resize, or accidental resize when trying to move: In the implementation the dead areas shall be used as ‘bumpers’ to reconcile the rounding-off effects in the sizes of the corner and side handles. you will get the same window as before but this time, you will see corners visible on the object for dragging. This is important because this is the only opportunity we have to communicate the size of the handle in a non-obstructive way. Selection Tools GIMP offers lots of ways to select a specific part of an image. Steps to Follow - Open GIMP. Modifying position and size of rectangle area in the tool options tab seems to be the perfect way to achieve what I want. I would disagree. Asking for help, clarification, or responding to other answers. On the exact creation moment of a fixed size rectangle (mouse-down) it shall be centred on the mouse pointer. the default value for the textfield shall be "1:1" for the selection tools, when there is no pending rectangle; for the crop tool it shall be : when there is no pending rectangle; when there is a pending rectangle for both selection or crop tools, then the string "Current" shall be displayed in the textfield and the values of the pending rectangle shall be used internally; in width mode, the default value for the textfield shall be ; in height mode, the default value for the textfield shall be ; in size mode, the default value for the textfield shall be "100x100". When the 'allow growing' option has been invoked by users, then the crop tool shall be in no way limited by the canvas or layer edge. For both select and crop tools, when the Highlight checkbox is checked, the darkening effect shall not be displayed during rubber-banding and moving. This will be quite a brief tutorial, but I see that a lot of users are searching Google with this question, so let’s help them out. When you resize your image, you are resizing the entire composition – including all of the layers within that composition (if you have more than one layer). site design / logo © 2021 Stack Exchange Inc; user contributions licensed under cc by-sa. GIMP's Scale Tool has always produced a floated selection if there is a selection existing when it is used. Also there shall be a 2-pixel line along the perimeter of the side handle itself. How do I tell the dimensions of the current selection in GIMP? for all images, for the rest of the session; the default value shall be displayed and used for this mode; anything else is ambiguous; no state or value change shall be undertaken; the value displayed before users' text input shall be restored. The two corner handles on the opposite side shall be hidden: As an implication of enforcing fixed width or height in the pending state, the side handles shall highlight as shown here: When the mouse goes down inside a corner handle and dragging commences, it shall be displayed and the other 3 hidden, to achieve a minimal-obstruction display: When the mouse goes down inside a side handle and dragging commences, or whenever fixed width or fixed height is enforced, it shall display a rectangle along the whole side of the bounding rectangle with a 1-pixel line. Also the panning of the image has an influence on everything. That means that is one is typed, it shall match any other in the previous user input. Impractical question: is it possible to find the regression line using a ruler and compass? The obvious work-arounds for this (zoom in, pan in) are productivity eaters, we need a real solution. Both the entered ratio and the resulting simplified ratio shall be added as user input for auto-completion. The interaction shall reflect this by showing the bounding rectangle in whatever size and position that users take it and the effective selection marching ants along the canvas edge where clipped. Right at the moment when both rubber-banding state and fixed mode become true, the fixed constraint shall be applied, with the anchor point as origin. This is the specification for the rectangle + oval selection, and the crop tools. When you click on image with the tool the Scaling Information dialog box is opened, allowing to change separately Width and Height. Open the GIMP application by double-clicking the shortcut or searching it through the Windows search feature. How to set a custom sized rectangle select area in gimp? The mouse position deltas from mouse-down are then used to control the non-contrained parameter (that is position for fixed size). The interaction shall reflect this by showing the bounding rectangle in the newly aligned position. Thank you. When the mouse is over one of the corner or side handles, and one of the up/down/right/left cursor keys is pressed, the rectangle shall be resized by one (shift: 15), When the mouse is over the move handle, and one of the up/down/right/left cursor keys is pressed, the rectangle shall be moved by one (shift: 15). This is necessary to achieve a stable cause-and-effect relationship between the position of the sprite, and the size of the bounding rectangle. Resizing an Image using GIMP You use the "Scale Image" feature to resize images in GIMP. The rest of the bounding rectangle area shall be the move handle: When users are enforcing fixed size in the pending state, the rectangle handles shall reflect this. Before going to explain each Gimp selection tool and its usage, let's see some standard properties: each Gimp selection tool can be drawn with left mouse button, generally held down. For fixed ratio/width/height: see selection tools above. In the sidebar, which is located on the left side of the screen by default, you can notice that there are quite a few selection tools. The change will be applied to all of the layers and not just the active layer. Without further ado, let’s get started! Who was listening to Bach's compositions in his lifetime? Step 2. of the top and bottom handles and the width of the left and right handles shall be calculated as usual. Areas between two adjacent corner handles are called side handles. In that case the rectangle (without handles) shall only be moved. This modification speeds up the setting of size or ratio to click–type–return. This will work for bounding rectangles down to a size of 45 pixels. Now click on the File menu in the menu bar and choose the Open option to open the image that you want to resize. The width and height modes shall not display the icons: The size mode is most identical to the ratio mode: It is extremely important that the textfield shall be a single textfield with no up/down arrows. unambiguous user value; User override state shall be entered for this particular mode (ratio, size, etc.) The right moment to recalculate handle sizes and decide if there is a narrow situation shall be after through zooming, panning or actual bounding rectangle size change, the on-screen pixel size of the bounding rectangle has changed. This is to prevent accidental move when trying to resize, or accidental resize when trying to move: the gray area shown here is purely for illustration in this spec and shall not be rendered in GIMP In the implementation the dead areas shall be used as ‘bumpers’ to reconcile the rounding-off effects in the sizes of the corner … I'm currently using Gimp to resize some images. gimp / gutenprint prob: gimp does not print bitpicker Linux - Software 0 04-08-2005 08:38 AM reposition gimp selection area without moving contents mrtwice Linux - Software 6 12-19-2003 05:26 PM gimp (1.3.21) and gimp-perl 0 Move the handles outside. this just leads to unnecessary noise in the interface. No state shall be reflected by the icons. 4.3.2. The '=' character shall not be displayed after simplification. I would rather want a way to set/modify the rectangle area explicitly, by having a dialog where I can input the size of rectangle in pixels and a way to move that area over the image using keyboard shortcuts, to make sure that I can select exactly the area I need and that I can get the selection rectangle there as soon as possible. From all three tool option panels, all the Fix buttons shall be removed. Showing corner handles does not make sense. After you have begin to draw the selection you can hold the keyboard button Shift to make it "snap" to a particular aspect ratio (perfect … So, to Focus change by means of double or single click: no change from default behaviour. Here we see rectangles with one and two dimensions of 45 pixels, also showing the side handles: If the size of one of the sides of the bounding rectangle is below 45 pixels, we have a narrow situation. In the other case: When one or more edges of the bounding rectangle is outside the canvas, then all of these edges shall be aligned with the corresponding canvas edges. Showing corner handles does not make sense, because only two of the sides can be adjusted. The algorithm for the size of the corner handles (handle height = bounding rectangle height / 4, CLAMPed by 15 and 50, handle width = bounding rectangle width / 4, CLAMPed by 15 and 50) allows fast interaction: what is black in this image shall be rendered inverted on the canvas. Therefore these two side handles shall be displayed (fixed height, left; fixed width, right): With no corner handles to compete with, the side handles shall occupy the whole side of the bounding rectangle. Learn to program BASIC with a Twitter bot, Podcast 309: Can’t stop, won’t stop, GameStop, Opt-in alpha test for a new Stacks editor, Visual design changes to the review queues. Click and drag them to resize … This interaction is not complete until the goal of keeping the sprite stable on the handle has been achieved. Only unambiguous user input shall be stored for auto completion re-use for the particular mode. What is left within the bounding rectangle are the dead areas, a drag by users starting in these shall do nothing, neither move, nor resize. By clicking “Post Your Answer”, you agree to our terms of service, privacy policy and cookie policy. This checkbox overrides that, and the layer/canvas can be size up by dragging a bigger rectangle around it. The height of the two horizontal side handles shall be exactly the corner handle height, and their width shall be the (bounding rectangle width - 3 * corner handle width), CLAMPed on the lower side by 15. This allows for precise adjustments. - Launch an image file. The interaction shall reflect this by showing the bounding rectangle in the newly calculated position; if the fixed width is greater than the actual canvas width, then the full width of the canvas shall be used; If users enforce a fixed height of the bounding rectangle and the top or bottom edge of the bounding rectangle is outside the canvas, then this edge shall be aligned with the corresponding canvas edges, and the from the resulting new bounding rectangle sizes the height enforcement shall be calculated. Only the visible part of the bounding rectangle goes into the size calculations. Under no circumstance shall GIMP itself get smart and toggle the checkbox, particularly not as a result of users entering or clearing text in the textbox. Especially with the elliptic select tool, this is part of creative workflow. The guides pop-up menu left side shall be aligned with the left sides of the checkboxes, the pop-up menu right side shall be aligned with the left sides of the textfields. This can be caused by actually narrow-sized bounding rectangles, but also by zooming out and panning out of view. for all images, for the rest of the session; the user entered value shall be used for this mode; unambiguous user clear; apart from that stripped out white space, nothing else was entered in the textfield; this shall enter the default state for this particular mode (ratio, size, etc.) The Width field shall be greyed-out when either fixed width or fixed size is enforced by the user. Making statements based on opinion; back them up with references or personal experience. The two corner handles on the opposite side shall be hidden: Corner handles shall not change in size during the rubber-banding of the size of the bounding rectangle. In plain language: the rectangle is grown/shrunk while the anchor point stays fixed. Only while rubber-banding (modifying) it shall be possible to enforce fixed ratio/widht/height/size. When the checkbox is checked, the constraint that is set by the user with the ratio/width/height/size pop-up list shall be enforced while rubber-banding a rectangle. A shall be the width, B shall be the height. If the 'Current layer only' option has been invoked by users, then all all behaviour specified above shall apply, substituting the layer (edge) for the canvas (edge). Unless you are using a very old version of gimp, you can resize the selection box after selecting by placing your mouse over one of the selected rectangle's sides: You can also set the size and position manually from the tool options tab: Thanks for contributing an answer to Super User!
