//! - *.bmp - bitmap image, lossless format without compression.
//! - *.ppm - PPM (Portable Pixmap Format), lossless format without compression.
//! - *.png - PNG (Portable Network Graphics) lossless format with compression.
//! - *.jpg, *.jpe, *.jpeg - JPEG/JIFF (Joint Photographic Experts Group) lossy format (compressed with quality losses). YUV color space used (automatically converted from/to RGB).
//! - *.tif, *.tiff - TIFF (Tagged Image File Format).
//! - *.tga - TGA (Truevision Targa Graphic), lossless format.
//! - *.gif - GIF (Graphical Interchange Format), lossy format. Color stored using pallete (up to 256 distinct colors).
//! - *.exr - OpenEXR high dynamic-range format (supports float pixel formats).
