* lisp/image.el (create-image): Remove supererogatory instances
of pcase. Recognize new `lambda' values and refrain from
specifying a default transform-smoothing when it is returned.
(image--default-smoothing): Return lambda if scaling is default.
* lisp/tool-bar.el (tool-bar--image-expression): Revert this
portion of last change.
* doc/lispref/display.texi (Image Descriptors): Document new
value of QCscale.
* lisp/cus-start.el (standard) <image-scaling-factor>: New
definition.
* lisp/image.el (image-scaling-factor): Move to C.
(create-image): Provide `default' as the default scaling factor.
(image--default-smoothing): Accept non-integer scaling factors.
(image-compute-scaling-factor): Document that this function
is no longer invoked by Emacs.
* lisp/tool-bar.el (tool-bar--image-expression): Disable
transform smoothing for tool-bar icons.
* src/dispextern.h (clear_image_cache): New definition.
* src/frame.c (gui_set_font): Clear such image cache entries as
derive their scales from the default font width.
* src/image.c (clear_image_cache): Export function.
(compute_image_size): Implement `default' by reading
Vimage_scaling_factor and/or computing a scale factor from the
frame's column width, as the case may be.
New argument F. All callers changed.
(syms_of_image) <Vimage_scaling_factor>: Move from image.el.
* lisp/image.el (image--compute-rotation): New function.
(image--compute-map, image--compute-original-map): Use it.
Ensure all transformations are applied or undone according to what
Emacs does internally. Call a transformation function only when
needed. Fix doc string.
(image--scale-map, image--rotate-map): Assume effective scale
argument.
(image--rotate-coord): Improve doc string.
(image--flip-map): Remove no more used argument FLIP.
* test/lisp/image-tests.el (image-create-image-with-map): Use a
valid SVG image otherwise `image-size' will not return a valid
value and calculation of scale could fail.
(image-transform-map): Update according to changed signature of
`image--flip-map'.
Now, when transforming an image, its :map is recomputed to fit.
Image map coordinates are integers, so when computing :map,
coordinates are rounded. To prevent an image from drifting from
its map after repeated transformations, 'create-image' now adds
a new image property :original-map, which is combined with the
image's transformation parameters to recompute :map.
* lisp/image.el (image-recompute-map-p): Add user option to
control whether :map is recomputed when an image is transformed.
(create-image): Create :map from :original-map and vice versa.
(image--delayed-change-size): Fix comment.
(image--change-size, image-rotate, image-flip-horizontally,
image-flip-vertically): Recompute image map after transformation
and mention 'image-recompute-map-p' in docstring.
(image--compute-map): Add function to compute a map from original
map.
(image--compute-original-map): Add function to compute an
original map from map.
(image--scale-map): Add function to scale a map based on :scale.
(image--rotate-map): Add function to rotate a map based on
:rotation.
(image--rotate-coord): Add function to rotate a map coordinate
pair.
(image--flip-map): Add function to flip a map based on :flip.
(image-increase-size, image-decrease-size, image-mouse-increase-size)
(image-mouse-decrease-size): Mention 'image-recompute-map-p' in
docstrings.
* etc/NEWS: Add NEWS entry.
* doc/lispref/display.texi (Image Descriptors): Document :original-map
and new user option 'image-recompute-map-p'.
* test/lisp/image-tests.el (image--compute-map-and-original-map):
Test 'image--compute-map' and 'image--compute-original-map'.
(image-tests--map-equal): Add equality predicate to compare image maps.
(image-create-image-with-map): Test that 'create-image' adds :map
and/or :original-map as appropriate.
(image-transform-map): Test functions related to transforming maps.
(Bug#69602)
* lisp/image.el (create-image, image-property): Add to do strings
link to description of image properties in ELisp manual.
* doc/lispref/display.texi (Defining Images): Fix example and add
cross-reference to where image properties are described.
(Image Descriptors): Add index entry.
* lisp/iimage.el (iimage-mode-buffer): Set context-menu-functions
text property to '(image-context-menu)'.
* lisp/image.el (image-context-menu): New function.
(put-image): Set context-menu-functions overlay property
to '(image-context-menu)'.
(insert-image, insert-sliced-image): Set context-menu-functions
text property to '(image-context-menu)'.
* lisp/mouse.el (context-menu-map): Use mouse-posn-property
'context-menu-functions' and call its funs at the end.
