The Raptor PIC Format is used by Raptor to store various images, sprites and tiles. The format is raw VGA data with a custom header.

File format

Data type Name Description
UINT32LE unknown1 Always 1 when iLineCount is 0
UINT32LE unknown2 Always 1 when iLineCount is 0
UINT32LE iLineCount Number of non-transparent image lines?
UINT32LE width Width of the image, in pixels
UINT32LE height Height of the image, in pixels
UINT8 data[] 8bpp raw VGA data, one byte per pixel; or sprite layout blocks

! The first two values are unknown. Possibly they might be hotspot coordinates. If iLineCount is 0 then the two values are always 1.

If iLineCount is 0, then the rest of the file are the raw pixel values (width*height bytes total) and the image has no transparent parts.

If iLineCount is NOT 0, then the rest of the file consists of multiple blocks in the following format:

 0 | UINT32LE     | iPosX		relative to left edge of image
 4 | UINT32LE     | iPosY		relative to top edge of image
 8 | UINT32LE     | iLinearOffset	relative to top-left pixel
12 | UINT32LE     | iCount		number of pixels to write (in that row)
16 | BYTE[iCount] | bPixels		pixels to write

The iLinearOffset value can be used to speed up the drawing process to a 320x200 pixel VGA video buffer. The iLinearOffset value could also be calculated like this:

iLinearOffset = iPosX + 320*iPosY

This formula could also be used as a validity check.

The actual value of iLineCount should not be used to detect the end of the image data. The PIC files appear to always end with a terminating data block where both iLinearOffset and iCount are set to -1 (0xFFFFFFFF) with no additional pixel data following that block.
