transform images with rotation, scaling, flipping, and shearing. The GIMP supports many common file formats: TIFF, GIF, JPEG, BMP, PPM, etc. Selections can be performed with rectangle, ellipse, and code for many platforms from the GIMP's home page (see http://www.XCF. Berkeley.EDU/~gimp/). The file will appear something like "gimp-0.54-linux-ELF-bin. tar.gz" and will be quite large. You will want "gimp" directory. You'll see README files and a file called "gimprc". You should execute "cp gimprc ~/.gimprc" to make a copy of your own gimp configuration file. You'll need to edit ~/.gimprc to add the path

lossless compression than BMP and GIF. TIF (or TIFF) Tagged Image File Format Store one or multiple images in the same file. Have an extensive set of options (which are outside the scope of this this book). RAW, CR2, etc… Raw image formats. (They are referred as RAW despite having other file extensions.) A good digital camera can store files in raw image formats, having minimal processing software Image processing software can store extra information, such as text and layers, in its own file format. If you save the image in these formats, you can open your image later and continue processing
