Emit ASM implementation for COLORMAP CLEAR instruction.

This function is called when you want to generate code that erases the entire color map, using the default foreground and background color.

Precondition

Bitmap must be enabled at least once with instruction BITMAP ENABLE.

Parameters

_environment

Current calling environment

Exceptions

EXIT_FAILURE

"CRITICAL: COLORMAP CLEAR WITH xxx AND xxx needs BITMAP ENABLED"

Definition at line 97 of file colormap_clear.c.

colormap_clear_with()

void colormap_clear_with	(	Environment *	_environment,
		int	_foreground,
		int	_background )

This function is called when you want to generate code that erases the entire color map, using a foreground and a background color. This function is useful if the color indices are given as integers.

Precondition

Bitmap must be enabled at least once with instruction BITMAP ENABLE.

Parameters

_environment	Current calling environment
_foreground	Index of foreground color
_background	Index of background color

Exceptions

EXIT_FAILURE

"COLORMAP CLEAR WITH xxx ON xxx needs BITMAP ENABLED"

Definition at line 58 of file colormap_clear.c.

colormap_clear_with_vars()

void colormap_clear_with_vars	(	Environment *	_environment,
		char *	_foreground,
		char *	_background )

Emit ASM implementation for COLORMAP CLEAR WITH [expression] ON [expression] instruction.

This function is called when you want to generate code that erases the entire color map, using a foreground and a background color. This function is useful if the color indices are given as integers.

Precondition

Bitmap must be enabled at least once with instruction BITMAP ENABLE.

Parameters

_environment	Current calling environment
_foreground	Expression for index of foreground color
_background	Expression for index of background color

Exceptions

EXIT_FAILURE

"CRITICAL: COLORMAP CLEAR WITH xxx AND xxx needs BITMAP ENABLED"
