Feature Description

Hello,

kimageformats package contains optional support of HEIF/HEIC format.

However, following piece of code prevents to use it:

I understand what is the intention. Macheif plug-in from Qt declare it supports both image/heic and image/heif mime types.

Technically the image/heic is the same (alias) as image/heif and it leads in glitch in save dialog, because the entry is doubled.

For this reason, the plugin from kimageformats declares support only for image/heif and not for the alias. Unfortunately, the image/heif mime type is filtered out by the flameshot code in screenshotsaver.cpp and the plugin from kimageformats is not used as result.

I guess it would be better to filter image/heic alias instead of image/heif

BTW, there is also another HEIF plug-in for Qt. It uses also other aliases: https://github.com/jakar/qt-heif-image-plugin/blob/master/src/heif.json

I suggest to filter aliases (image/heic, image/heic-sequence, image/heif-sequence) but to leave main image/heif unfiltered.
