Bug 916204 – app-editors/emacs-29.1.9999: USE="svg imagemagick" should pull in media-gfx/imagemagick[svg]

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Pascal Jäger 2023-10-24 06:54:01 UTC]

When emacs is compiled with USE=svg and USE=imagemagick and imagemagick is compiled with USE="-svg" it still wont display svg images and will display 'imagemagick error' in the messages buffer. 

When imagemagick is compiled with USE=svg svg-images are displayed properly in emacs. 

I think when emacs is compiled with svg support and imagemagick support it should depend on the svg USE-flag of imagemagick. 

Same goes for the jpeg and png I guess, but I haven't tested.

    app-editors/emacs: Add use-dependency on imagemagick
    
    Propagate the flags for the jpeg, png, svg and tiff backends. Otherwise,
    when visiting an image file, the following error will occur for svg:
    
    ImageMagick error: Document is empty
     `No such file or directory` @ error/svg.c/SVGError/3370
    
    For jpeg, png and TIFF, a different error message is printed:
    
    ImageMagick error: no decode delegate for this image format `PNG' @ error/constitute.c/ReadImage/746 [8 times]
    
    No error occurs for webp.

Same problem for the jpeg, png and tiff backends.

I've committed a fix for slots 29, 29-vcs and 30-vcs. Leaving this bug open: when there are no new issues introduced by this, I'll backport it to stable.
