Wikipedia
ILBM
Interleaved Bitmap (ILBM) is an image file format conforming to the Interchange File Format (IFF) standard. The format originated on the Amiga platform, and on IBM-compatible systems, files in this format or the related PBM (Planar Bitmap) format are typically encountered in games from late 1980s and early 1990s that were either Amiga ports or had their graphical assets designed on Amiga machines.A characteristic feature of the format is that it stores bitmaps in the form of interleaved bit planes, which gives the format its name; this reflects the way the Amiga graphics hardware natively reads graphics data from memory. A simple form of compression is supported to make ILBM files more compact.On the Amiga, these files are not associated with a particular file extension, though as they started being used on PC systems where extensions are systematically used, they employed a .lbm or occasionally a .bbm extension.

ILBM
ILBM is a subtype of the Interchange File Format used for storing picture data. ILBM stands for InterLeaved BitMap which refers to the way the pictures are stored. The image data is stored as a varying number of bitplanes, each storing one bit of data for each pixel in the image. The format supports horizontal and vertical RLE compression. Besides supporting TrueColor with or without an 8-bit alpha channel, the format is capable of closely matching the abilities and expectations of the original Amiga chipsets, of which three major revisions existed. On the OCS/ECS chipsets up to 6 bitplanes are supported, which would normally limit the number of colors to 64. However only 32 palette registers are available. Usage of one to five bitplanes is straightforward, according to binary progression. The first bitplane provides 2 colors, the second one doubles that to 4 colors, the third again doubles that to 8 colors, the fourth provides 16, and five bitplanes allows for 32 colors. With six bitplanes there are two display modes. Extra Half-Bright mode provides 64 colors, the last 32 being half as bright as the first. And more interestingly the Hold And Modify mode which while only making use of 16 palette colors, allowed the display of 4096 colors with some restrictions.
