The GNU Image Manipulation Program or “GIMP” is an excellent free and open source software created and maintained by a dedicated group of volunteer developers. This is an incredibly full-featured image editor with powerful tools to get the most out of your graphics and photos. Don’t let the complexity daunt you. Sometimes it’s just a very handy tool for doing simple tasks.
There are many reasons for resizing images. If you need a specific size for printing, or need to reduce the size to keep the file size down, or if your design uses multiple images and you want to adjust the size of different parts of your composition. may need to be changed. This article describes the various tools GIMP uses to resize images.
How to Resize Images Using Scale Images in GIMP
The easiest way to resize an image in GIMP is to use the Image Scale feature. Scale Image allows you to precisely set the image size in several units (percentages, pixels, mm, inches, etc.) and set the image resolution essential for rendering the image to screen or print.
GIMP’s image scaling feature resizes everything in the image canvas regardless of layers, so if you have multiple logos in the background image layer and the layer above the background, all these layers will scale accordingly. scaled. So it’s useful when you’ve worked with a larger design image and then need to scale it to a specific size for web applications or other size-critical uses.
1. [画像]>>[画像の拡大縮小]Click.
2. Set the width and height to resize the image. A “chain icon” can link two dimensions, so changing one will change the other, based on the aspect ratio of the image. These can be unlinked, but the image may be distorted. Image units can be changed using the px dropdown menu.
3. using the X and Y resolutions,[スケール]Click to set the image resolution. Print resolution is usually higher than screen resolution and is measured in pixels per inch (ppi).
The Tool Palette at the top left of the screen contains many useful tools, some of which are hidden. The Scale tool selects the currently active layer or any selected area and scales it in a manner similar to scaling an image.
The scale tool is especially useful when scaling an image on another layer. You can click to import the image into another layer in GIMP. File >> Open as Layer Select the image you want to add. Each layer can be selected using the layer menu (bottom right) and scaled independently of the overall image.
1. Click on the scale tool, It’s hidden in the upper left palette. Mouse over the icon to see all the tools it contains.
2. set the desired size,[スケール]Click. Note that the interface is very similar to Scale Image. Image aspect ratio Scaling can be used to scale without stretching or distorting. The unit of measure can also be changed using the drop-down menu.
3. Left-click and drag the handles around the image to scale the image interactivelyIf you select the lock icon in the scale tool dialog, you will notice that the aspect ratio of the image will be preserved and the new dimensions of the image will be updated in the associated input boxes.
Four. in the dialog box[スケール]Click to apply the scale and close the tool.
How to Crop Content in GIMP
If you use the scale tool to reduce the image size, you will notice that the canvas remains the original size of the image. This appears as a checkered section of blank canvas visible around the image.
To resize the canvas to the new image size,[画像]Click[内容に合わせてトリミング]Choose. This will automatically shrink the canvas to fit the reduced size image.
fit canvas to layer
If you use the scale tool to increase the image size, you will notice that the image is partially obscured because it does not fit on the original canvas.To fix this use File >> Image >> Fit Canvas to LayerClicking this option will automatically scale the canvas to fit larger images.
Change print size in GIMP
1. [画像]>>[印刷サイズ]Click to open the dialog.
2. Set the desired print size of the image,[OK]Click to set. Note that the unit of measure can be changed using the dropdown menu. As you change the print size, the number of pixels that make up the image remains the same, so if you reduce the size of the image for printing, you will notice that the resolution, or the number of pixels per inch or mm, increases. Similarly, increasing the size of an image will reduce its resolution. Increasing the size of an image spreads and decreases the number of pixels in a given area. This means that if you increase the image size significantly, the image quality will be degraded.
Using the techniques above gives you a variety of tools to control both the size and resolution of the images and designs you create. These are just the tip of the iceberg of GIMP’s capabilities, but they’re a great set of tools to boost your confidence as you explore this great application.
