Fix GDI+ image loading by file name

2020-04-25T13:37:46+00:00

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.

Use native image API for NS

2020-04-16T18:11:05+00:00

* configure.ac (NATIVE_IMAGE_API): Move above NS definitions.
(HAVE_NATIVE_IMAGE_API): Set for NS.
(HAVE_PNG, HAVE_JPEG, HAVE_GIF, HAVE_TIFF): Enable on NS builds.
* src/image.c (HAVE_NS): Fix a number of #if's so they no longer rely
on HAVE_NS.
(PIX_MASK_DRAW): Add for HAVE_NS so libpng support will compile.
(image_can_use_native_api):
(native_image_load): Add NS support.
(png_load):
(jpeg_load):
(tiff_load):
(gif_load): Remove NS specific definitions.
* src/nsimage.m (ns_can_use_native_image_api): New function.
* src/nsterm.h: (ns_can_use_native_image_api): New function.

Avoid compiler warning in image.c

2020-04-14T19:22:07+00:00

* src/image.c (image_can_use_native_api): Avoid compiler warnings
by making this function conditioned on HAVE_NATIVE_IMAGE_API.
(initialize_image_type): Call image_can_use_native_api only if
HAVE_NATIVE_IMAGE_API is non-zero.  Reported by Basil
L. Contovounesios .

; * src/image.c: Cleanup of #ifdef's related to HAVE_NATIVE_IMAGE_API.

Make use of MS-Windows native image API be selectable at run time

2020-04-14T15:10:41+00:00

* 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-Windows

2020-04-14T06:52:55+00:00

* 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) : 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.

Pacify gcc in xpm_scan

2020-04-06T17:37:22+00:00

* src/image.c (xpm_scan): Redo a loop for clarity.
This also pacifies --enable-gcc-warnings (GCC 9.3.1 x86-64 with -Og).
