How To Use Gimp On Iphone Xr
So you installed GIMP on your computer, congratulations! GIMP is a very powerful image manipulation software, but don’t let that intimidate you. Even if you don’t have time to learn advanced computer graphics, GIMP can still be a very useful and handy tool for quick image modifications.
It is my hope that these few examples will help to solve those small, quick modifications that you may need to apply to an image. Hopefully this will lead to learning even more powerful image editing capabilities that GIMP is capable of as well.
For quick access, these are the four main points I’ll cover in this quick tutorial:
In keeping with the spirit of the predecessor to this page, I will be using images from the Astronomy Picture of the Day (APOD), provided by NASA. App store web content.

All you need to know to follow these quick examples is to be able to find your image and open it:
- Use the File Open method to open the image in GIMP. Then, as mentioned before, the first step involves adding an alpha channel. Right-click on the layer in the right sidebar and select Add Alpha.
- In this video I will be showing you how to use GIMP, which is an image manipulation program and a great free alternative to Photoshop. This video will just b.
Changing the Size (Dimensions) of an Image (Scale)¶
You can also use this function on a Mac to save documents as a PDF by choosing the ‘Export to PDF’ option in the File menu. If you’re having issues sending MMS (multi-media texts) to Android users from your iPhone and converting the files isn’t working, there are a few things to try. Use Gimp How To Use GIMP. More importantly, these individuals put in the hard work to learn how to use GIMP. We reckon itll take about a month of occasional use to become competent and relaxed enough to actually enjoy using GIMP. And if you can do that then, bugs and lacklustre performance set aside, GIMP can become an incredibly powerful bit.
It’s a common problem that you may have an image that is too large for a particular purpose (embedding in a webpage, posting somewhere online, or including in an email for instance). In this case you will often want to scale the image down to a smaller size more suitable for your use.
This is a very simple task to accomplish in GIMP easily.
The image we’ll be using to illustrate this with is The Horsehead Nebula in Infrared.
When you first open your image in GIMP, chances are that the image will be zoomed so that the entire image fits in your canvas. The thing to notice for this example is that by default the window decoration at the top of GIMP will show you some information about the image.
Notice that the information at the top of the window shows the current pixel dimensions of the image (in this case, the pixel size is 1225×1280).
To resize the image to new dimensions, we need only invoke the Scale Image dialog:
Image → Scale Image…
This will then open the Scale Image dialog:
In the Scale Image dialog, you’ll find a place to enter new values for Width and Height. If you know one of the new dimensions you’d like for the image, fill in the appropriate one here.
You’ll also notice a small chain just to the right of the Width and Height entry boxes. This icon shows that the Width and Height values are locked with respect to each other, meaning that changing one value will cause the other to change in order to keep the same aspect ratio (no strange compression or stretching in the image).
For example, if you knew that you wanted your image to have a new width of 600px, you can enter that value in the Width input, and the Height will automatically change to maintain the aspect ratio of the image:
As you can see, entering 600px for the width automatically changes the height to 627px.
Also notice I have shown a different option under Quality → Interpolation. The default value for this is Cubic, but to retain the best quality it would better to use Sinc (Lanczos3).
If you want to specify a new size using a different type of value (other than Pixel size), you can change the type by clicking on the “px” spinner:
A common use for this could be if you wanted to specify a new size as a percentage of the old one. In this case you could change to “percent”, and then enter 50 in either field to scale the image in half.
Once you are done scaling the image, don’t forget to export the changes you’ve made:
to export as a new filename, or:
File → Overwrite {FILENAME}
to overwrite the original file (use caution).
For more detail about using Scale Image, you can see the documentation.
Changing the Size (Filesize) of a JPEG¶
You can also modify the filesize of an image when exporting it to a format like JPEG. JPEG is a lossy compression algorithm, meaning that when saving images to the JPEG format, you will sacrifice some image quality to gain a smaller filesize.
Using the same Horsehead Nebula image from above, I have resized it to 200px wide (see above), and exported it using different levels of JPEG compression:
As you can see, even at a quality setting of 80, the image is significantly smaller in filesize (77% size reduction), while the image quality is still quite reasonable.
When you’ve finished any image modifications you are doing, and are ready to export, simply invoke the export dialog with:
This will invoke the Export Image dialog:
You can now enter a new name for your file here. If you include the filetype extension (in this case, .jpg), GIMP will automatically try to export in that file format for you. Here I am exporting the image as a JPEG file.
You can also navigate to a new location on your computer through the Places pane, if you need to export the file to a different location. When you are ready to export the image, just hit the Export button.
This will then bring up the Export Image as JPEG dialog, where you can change the quality of the export:
From this dialog you can now change the quality of the export. If you also have the “Show preview in image window” option checked, the image on the canvas will update to reflect the quality value you input. This will also enable the “File size:” information to tell you what the resulting file size will be. (You may need to move some windows around to view the preview on the canvas in the background).
When you are happy with the results, hit the Export button to export.

Crop an Image¶
How To Use Gimp
There are numerous reasons you may want to crop an image. You may want to remove useless borders or information for aesthetic reasons, or you may want the focus of the final image to be of some particular detail for instance.
In a nutshell, cropping is just an operation to trim the image down to a smaller region than what you started with:
The procedure to crop an image is straightforward. You can either get to the Crop Tool through the tools palette:
Or you can access the crop tool through the menus:
Tools → Transform Tools → Crop
Once the tool is activated, you’ll notice that your mouse cursor on the canvas will change to indicate the Crop Tool is being used.

Now you can Left-Click anywhere on your image canvas, and drag the mouse to a new location to highlight an initial selection to crop. You don’t have to worry about being exact at this point, as you will be able to modify the final selection before actually cropping.
The Save as command displays the “Save Image” dialog. Since GIMP-2.8, the file is automatically saved in the XCF format and you can't save in another file format (for this, you have to export the file). The Save as dialog allows you to save with another name and/or to another folder.
- You can access this command from the image menubar through File → Save As…,
- or by using the keyboard shortcut Shift+Ctrl+S.
Figure 16.13. The “Save Image” dialog
- The left panel is divided into two parts. The upper part lists your main directories and your storage devices; you cannot modify this list. The lower part lists your bookmarks; you can add or remove bookmarks. To add a bookmark, select a directory or a file in the middle panel and click on the button at the bottom of the left panel. You can also use the Add to bookmarks command in the context menu, which you get by clicking the right mouse button. You can delete a bookmark by selecting it and clicking on the button.
- The middle panel displays a list of the files in the current directory. Change your current directory by double left-clicking on a directory in this panel. Select a file with a single left click. You can then save to the file you have selected by clicking on the button. Note that a double left click saves the file directly.You can right click on the middle panel to access the Show Hidden Files command.
- The selected image is displayed in the Preview window. File size, resolution and image composition are displayed below the preview window.If your image has been modified by another program, click on the preview to update it.
- Enter the filename of the new image file here.
Note If the image has already been saved, GIMP suggests the same filename to you. If you click on Save, the file is overwritten. - Above the middle panel, the path of the current directory is displayed. You can navigate along this path by clicking on one of the buttons.
- If you want to save the image into a folder that doesn't yet exist, you can create it by clicking on Create Folder and following the instructions.
- This button shows All Images by default. This means that all images will be displayed in the middle panel, whatever their file type. By developing this list, you can choose to show only one type of file.
- At Select File Type, you can select a compressed format for your XCF file.
