They say that small jars keep the best essences, and that could be said to be the case of Phocasa, a tiny free program that works as an image editor, and that computer programmers can use in the creation of their own programs.
If you need to create an image editor, take advantage of the occasion, because Phocasa allows you to rotate, resize, flip, etc. You can include it in your program and make it work through a command line. After clicking on Edit Picture, Phocasa will open a window and display that image, which you can edit at your leisure, after which you can contemplate.
Then the image will be saved and returned to your program, also having other functions such as undo, Revert (to return the image to its original state), Delete (delete the image from the hard disk), zoom (to enlarge or decrease the vision of the images) etc.
You can free download Phocasa 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
