Detailed Description

The Texture class contains methods for loading textures from disk and binding textures in OpenGL.

The class also provides a mechanism for mapping textures to names (strings) for easy reference.

Currently supported formats are: TIFF.

Depends on: libtiff.

Member Function Documentation

static void Texture::FreeTextureForName

(

const char

name[]

)

[static]

Release memory occupied by a texture accosiated with a name.

Parameters:

name

The name associated with the texture.

static int Texture::GetTextureByName

(

const char

name[]

)

[static]

Get the texture id for a texture name.

Parameters:

name

The name associated with the texture.

Returns:

The texture id assocated with the specified name, -1 if name is invalid.

static int Texture::LoadAndBindTexture	(	GLuint *	tex,
		const char	path[],
		GLuint	mode
	)			[static]

Load a tiff image from disk and bind it as the current texture.

Parameters:

	tex	Pointer to an GLuint that stores the ID of the texture loaded.
	path	The path specifying where the TIFF image can be found.
	mode	The internal GL storage mode

Returns:

0 on success, -EIO on error reading the TIFF image, 1 if the image does not conform to stric openGL standard and TEXTURE_FORCE_MAX_128 was defined when compiled, 2 if the image is not a power of 2 and TEXTURE_FORCE_POWER_OF_2 was defined when compiled.

static int Texture::LoadAndBindTexture	(	GLuint *	tex,
		const char	path[]
	)			[static]

Load a tiff image from disk and bind it as the current texture.

Parameters:

	tex	Pointer to an GLuint that stores the ID of the texture loaded.
	path	The path specifying where the TIFF image can be found.

Returns:

0 on success, -EIO on error reading the TIFF image, 1 if the image does not conform to stric openGL standard and TEXTURE_FORCE_MAX_128 was defined when compiled, 2 if the image is not a power of 2 and TEXTURE_FORCE_POWER_OF_2 was defined when compiled.

static int Texture::LoadTextureForName	(	const char	name[],
		const char	path[]
	)			[static]

Load a tiff image from disk, bind it as the current texture and associate it with a name for later reference.

Note that the parameter name must be unique!

Parameters:

	name	The name that should be associated with this texture.
	path	The path specifying where the TIFF image can be found.

Returns:

0 on success, -EIO on error reading the TIFF image, 3 if the name is already taken. Any error that can be reported by LoadAndBindTexture can also occure.

static int Texture::LoadTIFFImage	(	ImageHandle &	image,
		const char	path[]
	)			[static]

Load a tiff image from disk.

Parameters:

	image	A reference to a TIFF ImageHandle to hold the image data. If the image already contains data, the memory occupied by this data is returned to the system and the data is replaced by the new image data.
	path	The path specifying where the TIFF image can be found.

Returns:

0 on success, -EIO on error reading the TIFF image.
