Function Documentation

BOOLEAN STB_IMGConvertJPEG	(	U8BIT *	image_data,
		U32BIT	image_data_size,
		U8BIT **	output_data,
		U32BIT *	output_data_size,
		U16BIT *	pixel_width,
		U16BIT *	pixel_height
	)

Converts the given JPEG image data to a bitmap image that can be displayed on-screen, but no scaling is applied.

Parameters

image_data	- PNG image data
image_data_size	- number of PNG image data bytes
output_data	- address of pointer to buffer allocated for output data
output_data_size	- pointer to number of bytes in output bitmap
pixel_width	- pointer to returned width in pixels
pixel_height	- pointer to returned height in pixels

Returns

TRUE if image data is a valid PNG and conversion succeeds, FALSE otherwise
