This changeset also rearranges native image transform code for other platforms to make it cleaner, and also removes the support for native cropping. For the discussions, see https://lists.gnu.org/archive/html/emacs-devel/2019-06/msg00242.html * src/w32term.c (w32_image_rotations_p, transform): New functions. (w32_draw_image_foreground): If image rotation is requested and supported, call PlgBlt to transform the image. (w32_initialize): Populate the PlgBlt function pointer if it is supported. * src/w32term.h (w32_image_rotations_p): Add prototype. * src/dispextern.h (struct image) [HAVE_NTGUI]: New member xform. * src/image.c (compute_image_rotation): Renamed from image_set_rotation. Only compute and returns the rotation angle; leave the matrix calculation for later. Log an error message if the :rotation parameter is not a number. (image_set_crop): Function deleted. We no longer support native cropping, as one can display an image slice instead. (image_set_transform): Compute the transform matrix in its entirety here, in two variants: one for XRender and Cairo, the other for NS and MS-Windows. call compute_image_size and compute_image_rotation internally. (lookup_image) [HAVE_NATIVE_TRANSFORMS]: Call only image_set_transform. No need to pass the transform matrix to image_set_transform. (Fimage_transforms_p): Return a list of transform capabilities rather than a simple boolean. Support TTY frames as well. * src/nsimage.m (setTransform:): Don't invert the matrix, as it is already inverted in image.c. * test/manual/image-transforms-tests.el (test-cropping): State in the text that only ImageMagick supports cropping. * doc/lispref/display.texi (Image Descriptors): Update the documentation of native image transforms. (ImageMagick Images): Move the description of ':crop' here. * etc/NEWS: Minor copyedits of the feature announcement. |
