JPEG stands for Joint Photographic Experts Group, which is the name of the committee that standardised the format. JPG is a ‘lossy’ format, meaning that it is compressed to save storage space and make it easier to share. This compression can affect quality, but this loss of quality isn’...
Before you decide to use the BMP image file format, take a moment to consider its advantages and disadvantages. BMP file advantages. Each BMP is device-independent, meaning it can be stored and displayed across different devices and screens without losing quality. ...
each of which contains the color index of a single pixel. when the second byte is 2 or less, the escape has the same meaning as in encoded mode. in absolute mode, each run must be aligned on a word boundary.
meaning bi_rgb an uncompressed format. bi_rle4 an rle format for bitmaps with 4 bits per pixel. the compression format is a two-byte format consisting of a count byte followed by two word-length color indices. for more information, see the following remarks section. bi_rle8 a run-length...
Color indices are zero based, meaning a pixel color of 0 represents the first color table entry, a pixel color of 255 (if there are that many) represents the 256th entry. For images with more than 256 colors there is no color table. Raster Data encoding for 1bit / black & white ...

//is used to account for the bitmaps which use 32bpp format (normally //meaning that they have alpha channel) but have only zeroes in it so that //without this hack they appear fully transparent -- and as this is //unlikely intentional, we consider that they don't have alpha at all...
BMP, which stands for Bitmap, is a raster graphics image format that stores pixel data as a series of bits PNG, or Portable Network Graphics, is a raster graphics file format that was developed as a more advanced and flexible alternative to the widely us
cross platform support on all the major computer operating systems. Because bmp files are raster graphics files, image resolution is constrained meaning images in this format will not scale without loss in quality. This is in contrast to vector graphics images that can scale to arbitrary ...
0x0D in hexadecimal. This nomenclature comes from mechanical typewriters where a line of physical paper is fed through the roller (line feed) and the carriage is returned to the beginning of the line (carriage return). In text editors the meaning is the same, a 0x0A tells the editor to ...
