◆ CreateThumbnailFromSurface()

virtual bool IImage::CreateThumbnailFromSurface	(	unsigned char *	bufferin,
		unsigned int	width,
		unsigned int	height,
		unsigned int	format,
		unsigned int	pitch,
		const std::string &	destFile,
		unsigned char *&	bufferout,
		unsigned int &	bufferoutSize
	)

pure virtual

Encodes an thumbnail from raw bits of given memory location.

Remarks: Caller need to call ReleaseThumbnailBuffer() afterwards to free the output buffer

Parameters

bufferin	The memory location where the image data can be found
width	The width of the thumbnail
height	The height of the thumbnail
format	The format of the input buffer (JpegIO only)
pitch	The pitch of the input texture stored in bufferin
destFile	The destination path of the thumbnail to determine the image format from the extension
bufferout	The output buffer (will be allocated inside the method)
bufferoutSize	The output buffer size

pure virtual

Decodes the previously loaded image data to the output buffer in 32 bit raw bits.

Parameters

pixels	The output buffer
width	The width of the image
height	The height of the image
pitch	The pitch of the output buffer
format	The format of the output buffer (JpegIO only)

virtual bool IImage::LoadImageFromMemory	(	unsigned char *	buffer,
		unsigned int	bufSize,
		unsigned int	width,
		unsigned int	height
	)

pure virtual

Load an image from memory with the format m_strMimeType to determine it's size and orientation.

Parameters

buffer	The memory location where the image data can be found
bufSize	The size of the buffer
width	The ideal width of the texture
height	The ideal height of the texture
