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) |

README for the Emacs Lisp Reference Manual.
* This directory contains the texinfo source files for the Emacs Lisp
Reference Manual.
* Report bugs in the Lisp Manual (or in Emacs) using M-x report-emacs-bug.
To ask questions, use the help-gnu-emacs mailing list.
* The Emacs Lisp Reference Manual is quite large. It totals around
1100 pages in smallbook format; the info files total around 3.0 megabytes.
* You can format this manual for Info, for printing hardcopy using TeX,
or for HTML.
* You can buy nicely printed copies from the Free Software Foundation.
Buying a manual from the Free Software Foundation helps support our GNU
development work. See <https://shop.fsf.org/>.
(At time of writing, this manual is out of print.)
* The master file for formatting this manual for Tex is called 'elisp.texi'.
It contains @include commands to include all the chapters that make up
the manual.
* This distribution contains a Makefile that you can use with GNU Make.
** To make an Info file, you need to install Texinfo, then run 'make info'.
** Use 'make elisp.pdf' or 'make elisp.html' to create PDF or HTML versions.
