CacheTexture() [1/2]

bool CPicture::CacheTexture ( CTexture *  texture, uint32_t &  dest_width, uint32_t &  dest_height, const std::string &  dest, CPictureScalingAlgorithm::Algorithm  scalingAlgorithm = CPictureScalingAlgorithm::NoAlgorithm  )

static

Cache a texture, resizing, rotating and flipping as needed, and saving as a JPG or PNG.

Parameters

texture	a pointer to a CTexture
dest_width	[in/out] maximum width in pixels of cached version - replaced with actual cached width
dest_height	[in/out] maximum height in pixels of cached version - replaced with actual cached height
dest	the output cache file

Returns

true if successful, false otherwise
