* src/image.c (FRAME_SCALE_FACTOR): New #define for getting frame
scale factor.
(image_set_transform):
(svg_load_image): Use FRAME_SCALE_FACTOR.
* src/nsterm.m (ns_frame_scale_factor): Get the scale factor for an NS
frame.
Implement for non-Cairo X11 and NS. Count masks as well, and
XImage objects on X11.
* src/image.c (image_size_in_bytes): New.
(image_frame_cache_size): Use image_size_in_bytes.
* src/nsterm.h:
* src/nsimage.m (ns_image_size_in_bytes, [EmacsImage sizeInBytes]):
New function and method.
* src/w32gui.h:
* src/w32term.c (w32_image_size): Update signature.
* src/image.c (svg_load): Check `:base-uri' image property to
explicitly set base_uri for images embedded into SVG
(enum svg_keyword_index):

located relative to images `:base-uri'

reporting the size of frame image cache.
(image_frame_cache_size, Fimage_cache_size): The total size is
now of the type 'size_t', not 'int'.
* src/image.c (svg_css_length_to_pixels): Pass in a DPI value instead
of using a hard coded value.
(svg_load_image): Set the DPI on the rsvg_handle, and pass it to
svg_css_length_to_pixels.
* src/dispextern.h (struct image): Add original dimension elements.
* src/image.c (image_set_transform): Store the original dimensions.
(image_get_x_image): If we're using transforms use the original
dimensions with XGetImage.
* src/image.c (equal_lists): Remove.
(search_image_cache): Use Fequal instead of equal_lists.
Benchmarking shows no measurable time difference, and this
restores the cache semantics from Emacs 27 (where file names
didn't have to be EQ for the cache to be used).
* src/image.c (rsvg_handle_get_dimensions, init_svg_functions):
Make 'rsvg_handle_get_dimensions' available and defined for all
versions of librsvg. (Bug#44655)
This is a followup to last change in image.c.
* src/image.c (rsvg_handle_get_intrinsic_dimensions): Define to
call fn_rsvg_handle_get_intrinsic_dimensions.
(svg_css_length_to_pixels): Compile only for librsvg >= 2.46.0, as
RsvgLength type was not defined before.

viewBox size and applying it to the image.
* etc/PROBLEMS: Describe the problem with librsvg 2.45 and below.
* src/image.c (lookup_image): Make sure the frame's face cache
exists and has at least the basic faces. If FACE_ID is not a
basic face, and is no longer cached, fall back on the 'default'
face. (Bug#43700)
The new code calls 'malloc' and 'free', so we can no longer
* src/image.c (struct image_type): Rename 'load' to 'load_img' and
'free' to 'free_img'. All callers changed.
(free_image) [WINDOWSNT]: Don't #undef 'free'.
* test/manual/image-transforms-tests.el: Replace hard-coded colors
with defaults.
* src/dispextern.h (struct image):
* src/image.c (search_image_cache):
(xbm_load_image):

in another SVG to set a new size and colors, etc.
(lookup_image): Use the face colors instead of the frame colors.
(search_image_cache): Add ability to ignore the face colors.
(uncache_image): Uncache all copies of the image that share the spec,
even if the face colors don't match.
* etc/NEWS: Describe the changes.
* test/src/image-tests.el (image-test-circular-specs): New file.
* src/image.c (parse_image_spec): Return failure for circular lists.
(valid_image_p): Don't look at odd-numbered list elements expecting to
find a property name.
(image_spec_value): Handle circular lists.
(equal_lists): Introduce.
(search_image_cache): Use `equal_lists' (bug#36403).

when scaling up vs scaling down.

([EmacsImage setSmoothing:]): New functions.
* src/nsterm.h: Add definitions.
* src/nsterm.m (ns_dumpglyphs_image): Disable smoothing if requested.
* src/image.c (gif_load): When unable to parse a GIF specified
via a data attribute, don't message the complete binary, because
that's not useful (bug#40850).
Without a call to image_find_image, we can get a file name that
is relative to data-directory/images/, or a file name that
starts with "~/", in which case w32_load_image would fail.
* src/image.c (native_image_load): Call image_find_image_file to
resolve and encode the image file name.
* src/w32image.c (w32_load_image): No need to encode the file
name, as it's already encoded by native_image_load.
* configure.ac (NATIVE_IMAGE_API): Move above NS definitions.
(HAVE_NATIVE_IMAGE_API): Set for NS.
(HAVE_PNG, HAVE_JPEG, HAVE_GIF, HAVE_TIFF): Enable on NS builds.

on HAVE_NS.
(PIX_MASK_DRAW): Add for HAVE_NS so libpng support will compile.

(native_image_load): Add NS support.
(png_load):
(jpeg_load):
(tiff_load):
(gif_load): Remove NS specific definitions.
* src/nsimage.m (ns_can_use_native_image_api): New function.
* src/nsterm.h: (ns_can_use_native_image_api): New function.
* src/image.c (image_can_use_native_api): Avoid compiler warnings
by making this function conditioned on HAVE_NATIVE_IMAGE_API.
(initialize_image_type): Call image_can_use_native_api only if
HAVE_NATIVE_IMAGE_API is non-zero. Reported by Basil
L. Contovounesios <contovob@tcd.ie>.
* configure.ac: Minor cleanup in how w32image.o is added to the
build when native image APIs are requested.
* src/w32gui.h (w32_load_image, w32_can_use_native_image_api)
(w32_gdiplus_shutdown): Move prototypes from w32term.h here, since
w32.c doesn't include w32term.h.
* src/image.c (struct image_type): No need to pass TYPE to the
'valid_p' method. All callers changed.
(initialize_image_type) [HAVE_NATIVE_IMAGE_API]: Call
'image_can_use_native_api' before trying image-specific methods.
(image_can_use_native_api): New function.
(image_types): Remove the native_image_type parts.

'w32-use-native-image-API'.
* src/w32image.c: (w32_can_use_native_image_api): New function.
(gdiplus_init): Rename from w32_gdiplus_startup. Simplify code.
Move the call to GdiplusStartup to a separate function. Use
ordinal number for SHCreateMemStream if cannot load it by name.
(w32_load_image): Ignore Win32Error status from
w32_select_active_frame.
Move DEFSYMs from here...
* src/image.c (syms_of_image) [HAVE_NATIVE_IMAGE_API]: ...to here.
* etc/NEWS: Update the entry about native image API use.
* src/w32image.c: New file.
* src/w32term.h: Add prototypes of 'w32_load_image',
'w32_gdiplus_startup', 'w32_gdiplus_shutdown', and
'w32_query_frame_background_color'.
* src/w32term.c (w32_query_frame_background_color): No longer
static.
* src/w32.c (term_ntproc) [HAVE_GDIPLUS]: Call
'w32_gdiplus_shutdown'.
* src/image.c (struct image_type) <valid_p>: Accept an additional
argument, the image type. All implementations changed.
(init_native_image_functions, native_image_p, native_image_load)
[HAVE_NATIVE_IMAGE_API]: New methods for "native image type".
(initialize_image_type) [HAVE_NATIVE_IMAGE_API]: Call
'init_native_image_functions'.

image API.
