PVM Archive

A PVM archive is an archive that contains only PVR textures.

Format Description

Header

Offset	Length (bytes)	Description
0x0	4	"PVMH" magic code
0x4	4	Offset of the first texture in the archive minus 8
0x8	2	Flags: 0x1: Global Index 0x2: Texture Dimensions 0x4: Pixel & Data Format 0x8: Filenames
0xA	2	Number of textures in the archive

Entries

• The entry table starts at 0xC in the archive.
• The following is repeated for every entry in the archive.

Offset	Length (bytes)	Description	Only present if ...
0x0	2	Entry number in the archive (starts at 0)	Always
Varies	28	Filename	Filename flag is set
Varies	2	The texture's pixel format, followed by its data format	Pixel & Data Format flag is set
Varies	2	The texture's width (lower 4 bits) and height (upper 4 bits). Only the lower byte is used. Retrieve dimension using (1 << (value + 2)).	Texture Dimensions flag is set
Varies	4	Global Index	Global Index flag is set

Data

• Each texture is always aligned at a 16 byte offset.
• Each texture never contains a GBIX chunk (as its global index is defined above in the entry table), and as such always starts with a PVRT chunk.

Offset	Length (bytes)	Description
0x0	4	"PVRT" magic code
0x4	4	Length of the texture minus 8
0x8	...	PVR texture data not relevant to the archive
