uint32_t	UploadTextureFromDDSFile (const char *filename)
	Create a new GL texture directly from DDS file Uses NvAssetLoaderRead for opening the file.
uint32_t	UploadTextureFromFile (const char *filename)
	Create a new GL texture directly from any supported file- Uses NvAssetLoaderRead for opening the file.
uint32_t	UploadTextureFromDDSData (const char *ddsData, int32_t length)
	Create a new GL texture directly from DDS file-formatted data.
void	SupportsFormatConversion (bool convert)
	Indicates whether the GL level supports converting from format to internalFormat (basically, is this GLES or GL).

Detailed Description

GL-based image loading, representation and handling Support loading of images from DDS files and data, including cube maps, arrays mipmap levels, formats, etc.

The class does NOT encapsulate a GL texture object, only the client side pixel data that could be used to create such a texture

void NvImageGL::SupportsFormatConversion

(

bool

convert

)

Indicates whether the GL level supports converting from format to internalFormat (basically, is this GLES or GL).

Parameters:

[in]

convert

true if the API supports conversion

uint32_t NvImageGL::UploadTexture

(

NvImage *

image

)

Create a new GL texture and upload the given image to it.

Parameters:

[in]

image

the image to load

Returns:

the GL texture ID on success, 0 on failure

uint32_t NvImageGL::UploadTextureFromDDSData	(	const char *	ddsData,
		int32_t	length
	)

Create a new GL texture directly from DDS file-formatted data.

Parameters:

[in]	ddsData	the pointer to the DDS file data
[in]	length	the size in bytes of the file block

Returns:

the GL texture ID on success, 0 on failure

uint32_t NvImageGL::UploadTextureFromDDSFile

(

const char *

filename

)

Create a new GL texture directly from DDS file Uses NvAssetLoaderRead for opening the file.

See the documentation for that package to understand the correct paths

Parameters:

[in]

filename

the image filename (and path) to load

Returns:

the GL texture ID on success, 0 on failure

uint32_t NvImageGL::UploadTextureFromFile

(

const char *

filename

)

Create a new GL texture directly from any supported file- Uses NvAssetLoaderRead for opening the file.

See the documentation for that package to understand the correct paths

Parameters:

[in]

filename

the image filename (and path) to load

Returns:

the GL texture ID on success, 0 on failure
