Function Documentation

bitmap_enable()

void bitmap_enable	(	Environment *	_environment,
		int	_width,
		int	_height,
		int	_colors )

Emit ASM implementation for BITMAP ENABLE instruction.

This function can be called to emit the code to enable bitmap graphics on the target machine. Bitmap resolution and colors depends on hardware. Enabling the bitmap also sets the starting address in memory, for those computers that have graphics mapped in memory.

On some machine calling this instruction will define two special variables:

• BITMAPADDRESS (VT_ADDRESS) - the starting address of bitmap memory
• COLORMAPADDRESS (VT_ADDRESS) - the starting address of color map memory

Parameters

_environment

Current calling environment
