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.

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.
