Tex3DS routines.

Function Documentation

__attribute__()

struct __attribute__

(

(packed)

)

Tex3DS_GetNumSubTextures()

size_t Tex3DS_GetNumSubTextures

(

const Tex3DS_Texture

texture

)

Get number of subtextures.

Parameters

[in]

texture

Tex3DS texture

Returns

Number of subtextures

Tex3DS_GetSubTexture()

const Tex3DS_SubTexture* Tex3DS_GetSubTexture	(	const Tex3DS_Texture	texture,
		size_t	index
	)

Get subtexture.

Parameters

[in]	texture	Tex3DS texture
[in]	index	Subtexture index

Returns

Subtexture info

Tex3DS_TextureFree()

void Tex3DS_TextureFree

(

Tex3DS_Texture

texture

)

Free Tex3DS texture.

Parameters

[in]

texture

Tex3DS texture to free

Tex3DS_TextureImport()

Tex3DS_Texture Tex3DS_TextureImport	(	const void *	input,
		size_t	insize,
		C3D_Tex *	tex,
		C3D_TexCube *	texcube,
		bool	vram
	)

Import Tex3DS texture.

Parameters

[in]	input	Input data
[in]	insize	Size of the input data
[out]	tex	citro3d texture
[out]	texcube	citro3d texcube
[in]	vram	Whether to store textures in VRAM

Returns

Tex3DS texture

Tex3DS_TextureImportCallback()

Tex3DS_Texture Tex3DS_TextureImportCallback	(	C3D_Tex *	tex,
		C3D_TexCube *	texcube,
		bool	vram,
		decompressCallback	callback,
		void *	userdata
	)

Import Tex3DS texture.

@description For example, use this if you want to import from a large file without pulling the entire file into memory.

Parameters

[out]	tex	citro3d texture
[out]	texcube	citro3d texcube
[in]	vram	Whether to store textures in VRAM
[in]	callback	Data callback
[in]	userdata	User data passed to callback

Returns

Tex3DS texture

Tex3DS_TextureImportFD()

Tex3DS_Texture Tex3DS_TextureImportFD	(	int	fd,
		C3D_Tex *	tex,
		C3D_TexCube *	texcube,
		bool	vram
	)

Import Tex3DS texture.

Starts reading at the current file descriptor's offset. The file descriptor's position is left at the end of the decoded data. On error, the file descriptor's position is indeterminate.

Parameters

[in]	fd	Open file descriptor
[out]	tex	citro3d texture
[out]	texcube	citro3d texcube
[in]	vram	Whether to store textures in VRAM

Returns

Tex3DS texture

Tex3DS_TextureImportStdio()

Tex3DS_Texture Tex3DS_TextureImportStdio	(	FILE *	fp,
		C3D_Tex *	tex,
		C3D_TexCube *	texcube,
		bool	vram
	)

Import Tex3DS texture.

Starts reading at the current file stream's offset. The file stream's position is left at the end of the decoded data. On error, the file stream's position is indeterminate.

Parameters

[in]	fp	Open file stream
[out]	tex	citro3d texture
[out]	texcube	citro3d texcube
[in]	vram	Whether to store textures in VRAM

Returns

Tex3DS texture

Tex3DSi_ImportCommon()

static Tex3DS_Texture Tex3DSi_ImportCommon ( C3D_Tex *  tex, C3D_TexCube *  texcube, bool  vram, decompressCallback  callback, void *  userdata, size_t  insize  )

static

Tex3DSi_ReadData()

static bool Tex3DSi_ReadData ( decompressCallback  callback, void **  userdata, void *  buffer, size_t  size, size_t *  insize  )
