SceGxtErrorCode sceGxtCheckData

(

const void *

gxt

)

Checks if a pointer is a valid GXT file.

Parameters:

gxt	pointer to the GXT data

Return values:

SCE_OK
SCE_GXT_ERROR_INVALID_VALUE	Magic or version invalid

const void* sceGxtGetDataAddress

(

const void *

gxt

)

Gets the start address of the texture data.

Parameters:

gxt	pointer to the GXT data

Returns:

A pointer to the start of the texture data

uint32_t sceGxtGetDataSize

(

const void *

gxt

)

Gets the size of the texture data.

Parameters:

gxt	pointer to the GXT data

Returns:

The size of the texture data in bytes

uint32_t sceGxtGetHeaderSize

(

const void *

gxt

)

Gets the header size of a GXT file.

Parameters:

gxt	pointer to the GXT data

Returns:

The size of the header in bytes

uint32_t sceGxtGetTextureCount

(

const void *

gxt

)

Gets the texture count in a GXT file.

Parameters:

gxt	pointer to the GXT data

Returns:

The number of textures.

SceGxtErrorCode sceGxtSetPalette	(	SceGxmTexture *	texture,
		const void *	gxt,
		const void *	textureData,
		uint32_t	paletteIndex
	)

Sets the palette of a given texture.

Parameters:

texture	pointer to the texture
gxt	pointer to the GXT data
textureData	pointer to the start of texture data
paletteIndex	palette index

Return values:

SCE_OK
SCE_GXT_ERROR_INVALID_ALIGNMENT
SCE_GXT_ERROR_INVALID_VALUE
SCE_GXT_ERROR_INVALID_POINTER
