Detailed Description

Contains highlevel image related functions and mostly deals with the image caching, processing the image commands from the server, etc. It is gtk-specific as it returns gtk pixmaps.

void addsmooth	(	uint16	face,

Parameters:

face
smooth_face

Here is the caller graph for this function:

int associate_cache_entry	(	Cache_Entry *	ce,
		int	pixnum
	)

This functions associates image_data in the cache entry with the specific pixmap number. Currently, there is no failure condition, but there is the potential that in the future, we want to more closely look at the data and if it isn't valid, return the failure code.

Returns:: 0 on success, -1 on failure.

Here is the caller graph for this function:

int create_and_rescale_image_from_data	(	Cache_Entry *	ce,
		int	pixmap_num,
		uint8 *	rgba_data,
		int	width,
		int	height
	)

Takes the pixmap to put the data into, as well as the rgba data (ie, already loaded with png_to_data). Scales and stores the relevant data into the pixmap structure.

Parameters:

ce	can be NULL
pixmap_num
rgba_data
width
height

Returns:: 1 on failure.

void image_update_download_status	(	int	start,
		int	end,
		int	total
	)

Draws a status bar showing where we our in terms of downloading all the image data. A few hacks: If start is 1, this is the first batch, so it means we need to create the appropriate status window. If start = end = total, it means were finished, so destroy the gui element.

Parameters:

start	The start value just sent to the server.
end
total	The total number of images.

Here is the caller graph for this function:

void init_image_cache_data ( void )

Initializes the data for image caching Create question mark to display in each supported rendering mode when an image is not cached. When image caching is enabled, if a needed image is not yet in the cache, a question mark image is displayed instead. The image displayed is unique to the display mode. This function creates the image to use when OpenGL mode is in effect.

Here is the caller graph for this function:

void reset_image_data ( void )

Connecting to different servers, try to clear out any old images. Try to free the data to prevent memory leaks. This could be more clever, ie, if we're caching images and go to a new server and get a name, we should try to re-arrange our cache or the like.
