Windows 11 ARM Support

[scott-mackenzie]

Is there any intention to complie a binary for Windows 11 ARM? Or for Apple Silicon?

Hello, first I must finish export to Flatpak (linux).

Hello, first I must finish export to Flatpak (linux).

In my humble opinion you should abandon the Flatpak format as it is too expensive. You need to install a distro inside the Linux distro. AppImage is much more optimized and practical. Investing your time and efforts in an optimized format would be the most appropriate. /\ :)

I've been able to build it using the commands below. It sort of works, except bitmap images (JPEG and PNG) are coming up blank. I'm guessing I'm either missing a library or there might be an endian-ness issue. But I'm also missing a number of options on the Tools menu (see the screenshots), so I'm probably missing something.

@bjepson, you wrote,

I'm also missing a number of options on the Tools menu (see the screenshots)

If you used or tested a previous version earlier on, you may need to reset to factory settings to get all options shown. That was my experience with PDF4QT-1.4.0.0-x86_64.AppImage on Kubuntu 22.04, after testing PDF4QT 1.3.7 and daily builds earlier on.

Thanks, @SnowballV! I found that I needed to copy the plugin folder into the Release folder, and all the plugins appeared:

mkdir build\usr\bin\Release\pdfplugins
xcopy build\usr\bin\pdfplugins\Release\*dll build\usr\bin\Release\pdfplugins

I still have a problem with images not appearing, but I clicked Tools → Rendering Errors and saw this error: "Conversion to CMYK to output device using CMS failed.", but switching the renderer to QPainter seems to fix it.

I also realized that I save a few steps by using the vcpkg_with_qt.json (#68), though I had to remove ijg-libjpeg because of the conflict with libjpeg-turbo that's installed along with qt (I also needed to add blend2d for some reason). Here's the vcpkg.json that I'm using:

{
  "name": "pdf4qt",
  "version-string": "1.3.3",
  "dependencies": [ "blend2d", "openssl", "lcms", "zlib", "openjpeg", "freetype",  "libpng", "qt" ]
}

As a result, I need to make one change (a little quick and dirty) to Pdf4QtLibCore/sources/pdfutils.cpp:

266c266,267
<     libjpegInfo.version = tr("%1.%2").arg(JPEG_LIB_VERSION_MAJOR).arg(JPEG_LIB_VERSION_MINOR);
---
>     libjpegInfo.version = tr("%1").arg(JPEG_LIB_VERSION);
>     //libjpegInfo.version = tr("%1.%2").arg(JPEG_LIB_VERSION_MAJOR).arg(JPEG_LIB_VERSION_MINOR);

Here's what I'm doing now (also using the version of windeployqt from the build directory which simplifies things):
