Detailed Description

Implements an Image using experimental OpenGL.

This class contains a texture handle bound to the data given to the constructor; it draws a textured Quad to the screen.

See also: Image

Note: Width and height are not limited to powers of two; non-power of two images will be converted internally if they are not supported by the hardware (GLEE_ARB_texture_non_power_of_two).

Todo:: Check the correctness of the generateTexture function on big endian systems (ppc)

void FIFE::GLeImage::copySubimage	(	uint32_t	xoffset,
		uint32_t	yoffset,
		const ImagePtr &	img
	)

virtual

Copies given image into this one with respect to given offsets

Reimplemented from FIFE::Image.

Definition at line 384 of file gleimage.cpp.

References FIFE::Image::copySubimage().

void FIFE::GLeImage::forceLoadInternal ( )

virtual

Forces to load the image into internal memory of GPU

Implements FIFE::Image.

Definition at line 359 of file gleimage.cpp.

void FIFE::GLeImage::invalidate ( )

virtual

Invalidates the Image causing it to be reset or re-loaded

Implements FIFE::Image.

Definition at line 93 of file gleimage.cpp.

void FIFE::GLeImage::render	(	const Rect &	rect,
		uint8_t	alpha = `255`,
		uint8_t const *	rgb = `0`
	)

virtual

Renders itself to the current render target (main screen or attached destination image) at the rectangle rect. Convenience function

Parameters

rect	The position and clipping where to draw this image to.
alpha	The alpha value, with which to draw self.
rgb	The color value of overlay if any.

Implements FIFE::Image.

Definition at line 147 of file gleimage.cpp.

void FIFE::GLeImage::setSurface ( SDL_Surface * surface )

virtual

This frees the current suface and replaces it with the surface passed in the parameter (which can be NULL).

See also: Image::reset(SDL_Surface* surface)

Parameters

surface the SDL_Surface to use for this image

Implements FIFE::Image.

Definition at line 97 of file gleimage.cpp.

References FIFE::Image::reset().

void FIFE::GLeImage::useSharedImage	(	const ImagePtr &	shared,
		const Rect &	region
	)

virtual

After this call all image data will be taken from the given image and its subregion

Implements FIFE::Image.

Definition at line 340 of file gleimage.cpp.
