If you find that some elements in the image are squeezed or damaged by the process, you can create a mask to prevent this from happening. To see how this can be done, I’ll take this beach image and size it down from 3571 pixels wide to 3000. You might use this, for example, where you have a rectangular image that you want to make into a square image without losing any detail. The same tool can scale an image up to make it larger in one direction – and this time it will create extra data in the image to fill the space. You might use this, for example, to remove some empty area from the middle of an image where the more interesting parts of the image are to either side of it.
This gives you basically the same looking image but smaller in one dimension. You use it to reduce an image’s size but, where the crop tool removes the data from one or more sides of an image, content aware resizing removes it from the middle of the image. This plug-in is an alternative to the crop tool. Close Gimp, install the application and then reopen Gimp and you will see the application on the Layer menu. The tool is called Liquid Rescale which you can download from here.
Today I’m going to show you a plug-in for Gimp that does pretty much the same thing. I also mentioned the online application called Rsizr.
In a previous post, I looked at content aware resizing in Photoshop CS4 which is the same as in CS5.
