This file has been authored in the style of the INTERxxy.* file list

by Ralf Brown, and uses almost the same format.

Please read the file FILEFMTS.1ST before asking me any questions. You may find
|
|
|
|
|
that they have already been addressed.

should check it carefully to make sure your program will not break with

Some file formats were not released by their creators, others are regarded

as proprietary, which means that if your programs deal with them, you might

be looking for trouble. I don't care about this.

This format description applies to both PIC and MSK files created with the
|
|
|
|
|
Autodesk Animator Pro package. The file begins with a 64-byte header defined
|
|
|
|
|
as follows:
|
|
|
|
|
|
|
|
|
|
Offset Length Name Description
|
|
|
|
|
0000h 1 dword The size of the whole file including the size
|
|
|
|
|
of this header.
|
|
|
|
|
0004h 1 word ID=9500h
|
|
|
|
|
0006h 1 word Width of the image
|
|
|
|
|
0008h 1 word Height of the image
|
|
|
|
|
000Ah 1 word X offset of image
|
|
|
|
|
000Ch 1 word Y offset of image
|
|
|
|
|
000Eh 1 dword User ID, set to zero
|
|
|
|
|
0012h 1 byte Bits per pixel (8 for PIC, 1 for MSK)
|
|
|
|
|
0013h 45 byte reserved (0)
|
|
|
|
|
|
|
|
|
|
Following the file header are the data blocks for the image. Each data block
|
|
|
|
|
within a PIC or MSK file is formatted as follows:
|
|
|
|
|
|
|
|
|
|
OFFSET Count TYPE Description
|
|
|
|
|
0000h 1 dword The size of the block, including this header.
|
|
|
|
|
0004h 1 word Data type ID :
|
|
|
|
|
0 - Color palette info
|
|
|
|
|
1 - Byte-per-pixel image data
|
|
|
|
|
2 - Bit-per-pixel mask data
|
|
|
|
|
0006h ? byte Data
|
|
|
|
|
|
|
|
|
|
The type values in the block headers indicate what type of graphics data the
|
|
|
|
|
block contains.
|
|
|
|
|
|
|
|
|
|
In a PIC_CMAP block, the first 2-byte word is a version code;
|
|
|
|
|
currently this is set to zero. Following the version word are all 256 palette
|
|
|
|
|
entries in rgb order. Each of the r, g, and b components is a single byte in the
|
|
|
|
|
range of 0-255. This type of block appears in PIC files; there will generally be
|
|
|
|
|
no color map block in a MSK file.
|
|
|
|
|
|
|
|
|
|
In a PIC_BYTEPIXELS block, the image data appears immediately following the
|
|
|
|
|
6-byte block header. The data is stored as one byte per pixel, in left-to-right,
|
|
|
|
|
topD to-bottom sequence.
|
|
|
|
|
|
|
|
|
|
In a PIC_BITPIXELS block, the bitmap data appears immediately following the
|
|
|
|
|
6-byte block header. The data is stored as bits packed into bytes such that the
|
|
|
|
|
leftmost bits appear in the high-order positions of each byte. The bits are
|
|
|
|
|
stored in left-to-right, top-to bottom sequence. When the width of the bitmap is
|
|
|
|
|
not a multiple of 8, there will be unused bits in the low order positions of the
|
|
|
|
|
last byte on each line. The number of bytes per line is ((width+7)/8). This type
|
|
|
|
|
of block appears in MSK files.
