Member Function Documentation

allocAndCreatePixels()

virtual Byte * PngImage::allocAndCreatePixels ( )

virtual

Creates a new array of pixels on the heap. Caller must delete as this data is not managed.

Returns

Byte array.

Implements Image.

error()

static void PngImage::error ( png_struct * pHeader, png_const_charp error )

static

isValid()

static bool PngImage::isValid ( const char * filename )

static

read()

static void PngImage::read ( png_struct * pHeader, png_byte * pData, png_size_t length )

static

save() [1/2]

virtual void PngImage::save ( const char * file )

virtual

Saves a texture to the filesystem.

Parameters

Pointer	to texture.
The	texture's target-data to save. If not specified the QUAD target will be selected.

Implements Image.

save() [2/2]

static void PngImage::save ( const char * file, Texture * pTexture, TextureType target = QUAD_MAP )

static

warning()

static void PngImage::warning ( png_struct * pHeader, png_const_charp error )

static

write()

static void PngImage::write ( png_struct * pHeader, png_byte * pData, png_size_t length )

static

writeImageToFile()
