Function Documentation

bitmap_delete_rich()

void bitmap_delete_rich

(

bitmap_rich *

bmp

)

delete a rich bitmap created with bitmap_new_rich()

Parameters

bmp	The bitmap to delete

bitmap_display_pixel_r()

void bitmap_display_pixel_r	(	const bitmap_rich *	bmp,
		uint32_t	bmp_x,
		uint32_t	bmp_y,
		uint32_t	x,
		uint32_t	y
	)

display a specific rich bitmap pixel on the screen

Parameters

[in]	bmp	The bitmap
[in]	bmp_x	The bitmap x coordinate (in pixels)
[in]	bmp_y	The bitmap y coordinate (in pixels)
[in]	x	screen : x coordinate
[in]	y	screen : y coordinate

bitmap_get_pixel_r()

uint8_t bitmap_get_pixel_r ( const bitmap_rich *  bmp, uint32_t  x, uint32_t  y  )

inline

get the color of pixel from rich bitmap

Parameters

[in]	bmp	The bitmap
[in]	x	The bitmap x coordinate (in pixels)
[in]	y	The bitmap y coordinate (in pixels)

Returns

the color coded in a unsigned char : if (color >> 1) switch (color%2) { case 0: // WHITE break; case 1: // BLACK } else

bitmap_new_rich()

bitmap_rich* bitmap_new_rich	(	uint32_t	size_px_x,
		uint32_t	size_px_y,
		uint32_t *	color,
		bool	copy_color,
		uint32_t *	layout,
		bool	copy_layout
	)

{ function_description }

Parameters

[in]	size_px_x	The width in px
[in]	size_px_y	The height in px
	color	color origin
[in]	copy_color	if you want to make a copy, or only to make a link
	layout	layout origin -> can be set as 0 if it isn't needed
[in]	copy_layout	if you want to make a copy, or to make a link

Returns

a rich bitmap, ready to use !
