gla2DDrawInfo* glaBegin2DDraw	(	struct rcti *	screen_rect,
		struct rctf *	world_rect
	)

Save the current OpenGL state and initialize OpenGL for 2D rendering. glaEnd2DDraw should be called on the returned structure to free it and to return OpenGL to its previous state. The scissor rectangle is set to match the viewport.

This routine sets up an OpenGL state appropriate for drawing using both vertice (glVertex, etc) and raster (glRasterPos, glRect) commands. All coordinates should be at integer positions. There is little to no reason to use glVertex2f etc. functions during 2D rendering, and thus no reason to +-0.5 the coordinates or perform other silly tricks.

Parameters:

screen_rect	The screen rectangle to be used for 2D drawing.
world_rect	The world rectangle that the 2D area represented by screen_rect is supposed to represent. If NULL it is assumed the world has a 1 to 1 mapping to the screen.

void glaDefine2DArea

(

struct rcti *

screen_rect

)

Define a 2D area (viewport, scissor, matrices) for OpenGL rendering. This routine sets up an OpenGL state appropriate for drawing using both vertice (glVertex, etc) and raster (glRasterPos, glRect) commands. All coordinates should be at integer positions. There is little to no reason to use glVertex2f etc. functions during 2D rendering, and thus no reason to +-0.5 the coordinates or perform other silly tricks.

Parameters:

screen_rect

The screen rectangle to be defined for 2D drawing.

		float	y,
		int	img_w,

		int	row_w,
		int	format,
		int	type,
		void *	rect
	)

Functions like a limited glDrawPixels, except ensures that the image is displayed onscreen even if the x and y coordinates for would be clipped. The routine respects the glPixelZoom values, pixel unpacking parameters are _not_ respected.

Attention:

This routine makes many assumptions: the rect data is expected to be in RGBA unsigned byte format, the coordinate (0.375, 0.375) is assumed to be within the view frustum, and the modelview and projection matrices are assumed to define a 1-to-1 mapping to screen space.

Furthmore, in the case of zoomed or unpixel aligned images extending outside the view frustum, but still within the window, some portion of the image may be visible left and/or below of the given x and y coordinates. It is recommended to use the glScissor functionality if images are to be drawn with an inset view matrix.

void glaRasterPosSafe2f	(	float	x,

Functions like glRasterPos2i, except ensures that the resulting raster position is valid. known_good_x and known_good_y should be coordinates of a point known to be within the current view frustum.

Attention:

This routine should be used when the distance of x and away from the known good point is small (ie. for small icons and for bitmap characters), when drawing large+zoomed images it is possible for overflow to occur, the glaDrawPixelsSafe routine should be used instead.
