* src/image.c (svg_load_image): Check how many bytes were actually
written to the buffer. Don't check xmalloc return value as xmalloc
doesn't return if it fails.
* src/image.c (UINT32) [TIFFLIB_VERSION >= 20210416]: Define to
use stdint.h type for recent libtiff versions. Reported by Andy
Moreton <andrewjmoreton@gmail.com>.
* src/image.c (image_find_image_fd): Don't return an encoded filename
string.
* src/nsfns.m: ([NSString stringWithLispString:]): Clarify usage
comment.
* src/nsimage.m ([EmacsImage allocInitFromFile:]): No need to encode
the filename when converting to NSString.
* src/image.c (image_get_dimension): New function.
(compute_image_size): Use image_get_dimension to set the sizes, and
pass in the image struct instead of just the spec.
(image_set_transform):
(imagemagick_load_image):
(svg_load_image): Use the image instead of the spec in compute_image_size.
(syms_of_image): Add 'em' as a symbol.
* src/image.c: (init_svg_functions) [WINDOWSNT]: Define and load
rsvg_handle_set_stylesheet from the DLL for librsvg > 2.48.
(lookup_image): Use xmalloc.
* src/dispextern.h (struct image): Add font details required for the CSS.
* src/image.c (free_image): Free the font family string.
(search_image_cache):
(uncache_image): Make image caching understand the font details.
(lookup_image): Handle the font details when generating the image and
looking up the cache.
(svg_css_length_to_pixels): Handle 'em' when we know the font size.
(svg_load_image): Generate the CSS and apply it to the SVG.
(enum svg_keyword_index):
(svg_format):
(syms_of_image): Add ':css' attribute.
* doc/lispref/display.texi (SVG Images): Add details of new svg image
attributes.
* 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):
(svg_format): Add :base-uri.
* lisp/svg.el (svg-embed-base-uri-image): New function to embed images
located relative to images `:base-uri'
* src/image.c (rsvg_handle_set_dpi_x_y) [WINDOWSNT]: DEF_DLL_FN it.
(init_svg_functions): LOAD_DLL_FN rsvg_handle_set_dpi_x_y.
<rsvg_handle_set_dpi_x_y>: Define as a macro
* src/w32term.c (w32_image_size): New function.
* src/image.c (image_frame_cache_size) [HAVE_NTGUI]: Support
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.
