However, using the – resize options we have covered, it is, of course, perfectly feasible to enlarge our image. To install ImageMagick on Debian and Ubuntu, have to compile the application from the source code. It's cross-platform, and it is available for most operating systems, including any Linux, Windows, macOS, and other platforms. To conclude this section, typically, the most common way to change the size of an image is to shrink it to fit the desired size. You can use it to resize and transform images, add text overlays, draw shapes, add effects, do color edits, etc. I looked at ImageMagick for iphone (its on Cydia) but didnt get anywhere. Consequently, the actual scale may not exactly match the scaling factor we provide, but it will be very close. This works for APT-based distros: Debian, Ubuntu and derivatives (Linux Mint. This will scale the image by the amount specified: convert flower_original.jpeg -resize 50% half_flower.jpegįor most of us, this type of scaling will be perfectly fine, but we should note that the final pixel size of the image will be rounded to the nearest integer. Similarly, we can also specify a percentage value when using the resize option. In this example, we fit our original flower image into a smaller square box 64×64 pixels in size: Accepted imagemagick 8:6.9.7.4+dfsg-11+deb9u14 (source) into oldoldstable ( Andreas Rnnquist ) Accepted imagemagick 8:6. You can probably find supplementary information in the debian-release archives or in the corresponding bug. We can build on the previous example by using the -resize option of the convert command: convert flower_original.jpeg -resize 64圆4 flower_64圆4.jpeg You might want to ensure that your package is ready for it. Another typical operation is image resizing.
