Function Documentation

◆ create_sprite()

struct sprite * create_sprite	(	int	width,
		int	height,
		struct color *	pcolor
	)

Create a sprite with the given height, width and color.

Definition at line 131 of file sprite.c.

◆ crop_sprite()

struct sprite * crop_sprite	(	struct sprite *	source,
		int	x,
		int	y,
		int	width,
		int	height,
		struct sprite *	mask,
		int	mask_offset_x,
		int	mask_offset_y,
		float	scale,
		bool	smooth
	)

Create a new sprite by cropping and taking only the given portion of the image.

source gives the sprite that is to be cropped.

x,y, width, height gives the rectangle to be cropped. The pixel at position of the source sprite will be at (0,0) in the new sprite, and the new sprite will have dimensions (width, height).

mask gives an additional mask to be used for clipping the new sprite. Only the transparency value of the mask is used in crop_sprite. The formula is: dest_trans = src_trans * mask_trans. Note that because the transparency is expressed as an integer it is common to divide it by 256 afterwards.

mask_offset_x, mask_offset_y is the offset of the mask relative to the origin of the source image. The pixel at (mask_offset_x,mask_offset_y) in the mask image will be used to clip pixel (0,0) in the source image which is pixel (-x,-y) in the new image.

scale gives scale of new tileset smooth means if scaling might be bilinear, if set to false use nearest neighbor

◆ ctor_sprite()

static struct sprite * ctor_sprite ( SDL_Surface * surf )

static

Create a sprite struct and fill it with SDL_Surface pointer

Definition at line 174 of file sprite.c.

◆ free_sprite()

void free_sprite ( struct sprite * s )

Free a sprite and all associated image data.

Definition at line 164 of file sprite.c.

◆ get_sprite_dimensions()

void get_sprite_dimensions	(	struct sprite *	sprite,
		int *	width,
		int *	height
	)

Find the dimensions of the sprite.

Definition at line 155 of file sprite.c.

◆ gfx_fileextensions()

const char ** gfx_fileextensions ( void )

Return a NULL-terminated, permanently allocated array of possible graphics types extensions. Extensions listed first will be checked first.

Definition at line 40 of file sprite.c.

◆ load_gfxfile()

struct sprite * load_gfxfile	(	const char *	filename,
		bool	svgflag
	)

Load the given graphics file into a sprite. This function loads an entire image file, which may later be broken up into individual sprites with crop_sprite().

Definition at line 68 of file sprite.c.

◆ load_gfxnumber()

struct sprite * load_gfxnumber ( int num )

Return a sprite image of a number.

Definition at line 186 of file sprite.c.
