Move imagep in image.c from the debugging section

2022-09-13T14:37:31+00:00

* lisp/simple.el (imagep): Remove.
* src/image.c (Fimagep): Always define.

; * src/image.c (svg_load_image): Another minor cleanup. (Bug#51104)

2022-09-13T14:12:40+00:00

; * src/image.c (svg_load_image): Always free 'err' if non-NULL.

2022-09-13T13:38:50+00:00

Fix last change in image.c

2022-09-13T13:26:50+00:00

* src/image.c (svg_load_image): Don't call Lisp to remove trailing
whitespace from librsvg error messages, do it in C instead; this
reduces consing and is much cleaner.  Don't display empty error
reason if librsvg happens to return an empty message text.
(syms_of_image): Don't DEFSYM string-trim-right.  (Bug#57755)

Avoid double svg error reporting and segfaults

2022-09-13T11:57:44+00:00

* src/image.c (svg_load_image): Use g_error_free directly instead
of the helder g_clear_error (since we're only calling it with
non-nil values).
(svg_load_image): Avoid segfault and double reporting errors.
* test/manual/image-tests.el (image-tests-load-image/svg-too-big)
(image-tests-load-image/svg-invalid): Test it (bug#57755).

Display librsvg error when loading bad SVG

2022-09-09T01:07:44+00:00

* src/image.c (svg_load_image): Display the error message from librsvg
when parsing a bad SVG image file.
* test/manual/image-tests.el
(image-tests-load-image/svg-invalid): New test.

Prune animation cache when images are no longer reachable

2022-07-14T16:59:09+00:00

* lisp/image.el (image-animate-timeout): Eject cached animated
images that are no longer reachable (bug#56546).

* src/image.c (Fclear_image_cache): Allow specifying a cached
animated image to eject.
(gif_load, webp_load): Adjust what to use as the caching key --
the identity of the list itself is apparently changed by some
callers.

Make image-cache-size also include the animation cache

2022-07-14T16:59:09+00:00

* src/image.c (struct anim_cache, anim_create_cache): Store approx
cache size.
(gif_load, webp_load): Ditto.
(Fimage_cache_size): Also report animation cache size (bug#56546).

Pacify -Wunused-macros in --without-all builds

2022-07-14T12:02:27+00:00

* src/image.c (IMAGE_TYPE_INIT): Make conditional on image support.

Make clear-image-cache clear the animation cache

2022-07-14T09:49:47+00:00

* src/dispextern.h: Declare image_prune_animation_caches for use
in gc.

* src/image.c (Fclear_image_cache): Clear animation cache.
(anim_prune_animation_cache, anim_get_animation_cache): Allow
clearing in addition to pruning.
(imagemagick_prune_animation_cache)
(imagemagick_get_animation_cache): Ditto.
(image_prune_animation_caches): New function (bug#56546).
