Print Page - pipine svg results in differing output from passing filename as arg

Title: pipine svg results in differing output from passing filename as arg
Post by: richardmonette on October 14, 2022, 11:33:46 AM

Running

main> exiftool test.svg

reports

File Type : SVG
File Type Extension : svg
MIME Type : image/svg+xml

which is what I would expect, however running (as a pipe)

main> cat test.svg | exiftool -

reports

File Type : XMP
File Type Extension : xmp
MIME Type : application/rdf+xml

which I believe is unexpected (and arguably incorrect), one would have expected the same result as when opening via filename.

Is there a way to have the piped version also report the expected SVG info?

Thank you!

If the file begins with "<svg" then it should be identified as SVG when read via a pipe.

How does your file start?

Hi Phil,

Thank you for taking the time to look at my bug report!

Here is a more complete reproduction case:

Code Select

main> cat circle.svg
<svg height="100" width="100">
  <circle cx="50" cy="50" r="40" stroke="black" stroke-width="3" fill="red" />
  Sorry, your browser does not support inline SVG.
</svg>
main> cat circle.svg | exiftool -

Svg Circle Stroke              : black
Svg Circle Stroke-width        : 3
Svg Circle Fill                : red
main> exiftool -ver
12.30
main>

I've also reproduced the same troublesome behaviour with

Code Select

<svg width="215" height="61" viewBox="0 0 215 61" fill="none" xmlns="http://www.w3.org/2000/svg">
as my first line.

Code Select Expand
ExifTool Version Number : 12.30

That's likely your problem right there. Try the current version.
