Function Documentation

void evas_image_cache_flush ( Evas * e )

Flush the image cache of the canvas.

Parameters

e	The given evas pointer.

This function flushes image cache of canvas.

References evas_canvas_image_cache_flush.

void evas_image_cache_reload ( Evas * e )

Reload the image cache.

Parameters

e	The given evas pointer.

This function reloads the image cache of canvas.

References evas_canvas_image_cache_reload.

void evas_image_cache_set	(	Evas *	e,
		int	size
	)

Set the image cache.

Parameters

e	The given evas pointer.
size	The cache size.

This function sets the image cache of canvas in bytes.

References evas_canvas_image_cache_set.

int evas_image_cache_get ( const Evas * e )

Get the image cache.

Parameters

e	The given evas pointer.

This function returns the image cache size of canvas in bytes.

References evas_canvas_image_cache_get.

Eina_Bool evas_image_max_size_get	(	const Evas *	e,
		int *	maxw,
		int *	maxh
	)

Get the maximum image size evas can possibly handle.

Parameters

e	The given evas pointer.
maxw	Pointer to hold the return value in pixels of the maximum width
maxh	Pointer to hold the return value in pixels of the maximum height

This function returns the larges image or surface size that evas can handle in pixels, and if there is one, returns EINA_TRUE. It returns EINA_FALSE if no extra constraint on maximum image size exists. You still should check the return values of maxw and maxh as there may still be a limit, just a much higher one.

Since: 1.1
