Detailed Description

[Impl] image implementation (encapsulates system resources).

Member Function Documentation

virtual

reads and init an image from a file.

the filetype can be one of "gif" "jpeg" "xpm" or null in which case the type is deduced from the filename suffix. returns the UFileStat.

virtual void ubit::UHardIma::setRaster	(	int	width,
		int	height,
		int	alpha_hint
	)

pure virtual

inits the raster with this size (previous data is destroyed if any).

the pixel raster is created if width AND height are > 0. It is null otherwise. The previous pixel raster is always destroyed, if any.

'alpha_hint' specifies if the buffer has an alpha channel. it can be 0 (no alpha) or 1 (bitmask) for X11 and 8 (8 alpha bits) for GL.
