Conversion Error with SVG to PNG via ImageMagick

Open StrangeRanger opened this issue 9 months ago • 0 comments

Describe the bug

When trying to convert an SVG into a PNG via ImageMagick, I get a conversion error:

convertx  | jobId set to: 26
convertx  | stderr: magick: delegate failed `'rsvg-convert' --dpi-x %x --dpi-y %y -o '%o' '%i'' @ error/delegate.c/InvokeDelegate/1919.
convertx  | magick: unable to open file '/tmp/magick-G__M7MFUgIJuchSiSBAeNkf92hBMB2Q4': No such file or directory @ error/constitute.c/ReadImage/785.

convertx  | Failed to convert ./data/uploads/1/26/logo-black.svg from svg to png using imagemagick. error: Error: Command failed: magick ./data/uploads/1/26/logo-black.svg ./data/output/1/26/logo-black.png
convertx  | magick: delegate failed `'rsvg-convert' --dpi-x %x --dpi-y %y -o '%o' '%i'' @ error/delegate.c/InvokeDelegate/1919.

What works with svg to png:

  • resvg
  • vips
  • graphicsmagick
  • inkscape
    • Though it does produce the following warnings:
    convertx  | ** (inkscape:114): WARNING **: 20:40:55.043: Failed to wrap object of type 'PangoFT2FontMap'. Hint: this error is commonly caused by failing to call a library init() function.

convertx  | ** (inkscape:114): WARNING **: 20:40:56.592: Failed to wrap object of type 'GtkRecentManager'. Hint: this error is commonly caused by failing to call a library init() function.
  • ffmpeg
    • Though it does output a notice regarding a pattern thing, which I'm sure is fine:
    convertx  | [image2 @ 0xaaaadf69aac0] The specified filename './data/output/1/29/logo-black.png' does not contain an image sequence pattern or a pattern is invalid.
convertx  | [image2 @ 0xaaaadf69aac0] Use a pattern such as %03d for an image sequence or use the -update option (with -frames:v 1 if needed) to write a single image.
