* Fix GDI+ image loading by file nameEli Zaretskii2020-04-251-1/+0
| | | | | | | | | | 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.
* Remove workaround from w32image.cEli Zaretskii2020-04-201-2/+0
| | | | | | * src/w32image.c (w32_load_image): Remove a workaround for a bug that is not needed anymore. This error was happening because GDI+ functions were called as CDECL, not as STDCALL.
* Rework how GDI+ functions are loaded dynamically in w32image.cEli Zaretskii2020-04-191-43/+102
| | | | | | | | | | * src/w32image.c: Define correct WINGDIPAPI typedefs for GDI+ functions. We cannot use DEF_DLL_FN, since that is for functions with C calling conventions, whereas GDI+ functions are __stdcall. (gdiplus_init): Load functions from DLL manually, not via LOAD_DLL_FN, as the latter is for __cdecl functions. (w32_frame_delay): Initialize delay with a negative value, as zero is a valid delay.
* Don't abort when using GDI+ for imagesEli Zaretskii2020-04-181-7/+14
| | | | | | * src/w32image.c (decode_delay): Instead of aborting when the type of delay value is unrecognized, return an invalid negative value.
* Fix loading multi-frame TIFF images via GDI+Juan José García-Ripoll2020-04-181-18/+24
| | | | | | | * src/w32image.c (w32_frame_delay): Don't try to compute frame delay if GdipGetPropertyItemSize fails for PropertyTagFrameDelay. (w32_load_image): Don't add 'delay' member to metadata if the delay could not be determined.
* ; * src/w32image.c (w32_select_active_frame): Comment about GUID values.Eli Zaretskii2020-04-161-0/+5

* File-handling cleanup in w32image.cEli Zaretskii2020-04-161-11/+8
| | | | | | | | | * src/w32image.c (w32_load_image): Encode the image file name and convert it via 'map_w32_filename'. No need to do anything special when 'w32_unicode_filenames' is zero, since file names are in UTF-8 internally, and this code will never run on Windows 9X. * src/w32.h (map_w32_filename): Add prototype; removed prototypes from all *.c files.
* Fix retrieval of frame delay when using GDI+Eli Zaretskii2020-04-151-3/+41
| | | | | | | * src/w32image.c (enum PropertyItem_type): New enumeration. (decode_delay): New function. (w32_frame_delay): Call 'decode_delay' to retrieve the frame delay from image data.
* Make use of MS-Windows native image API be selectable at run timeEli Zaretskii2020-04-141-81/+143
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | * 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. (syms_of_image): New symbol 'native-image'. (parse_image_spec): Accept native-image "type" for any image type. * src/w32term.c (syms_of_w32term): New variable '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.
* Initial version of native image API support for MS-WindowsJuan José García-Ripoll2020-04-141-0/+306
* 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_types) [HAVE_NATIVE_IMAGE_API]: Add settings for native image API. (lookup_image_type) [HAVE_NATIVE_IMAGE_API]: Initialize native functions if needed. * lisp/term/w32-win.el (dynamic-library-alist): Add gdiplus and shlwapi. * etc/NEWS: Announce the new feature. * configure.ac (native-image-api): New option, OFF by default. (HAVE_NATIVE_IMAGE_API): If native-image-api is selected, add w32image.o to W32_OBJ.
