ImageMagick and subprocess

[Mahmoodreza Aarabi]

Hello guys

There is a command based software for converting images and formats named ImageMagick

i created an ui to give artist to use commands of imageMagick easily, when i run command for converting my images, it works until a file has problem, in this way magick give an error that i can’t get it as an exception to handle it.
error: magick: Incompatible type for "RichTIFFIPTC"; tag ignored.TIFFFetchNormalTag’ @ warning/tiff.c/TIFFWarnings/905.`

there is any experience to help?
or using other modules is better than this?
for example OpenImageIO of sony picture, it have module for python?

thanks

Hi,
You have check imagemagick/whatever-app return codes by getting its stdin/stdout/stderr pipes (check subprocess docs, it is straight forward).

Cheers!

If you're running this from python, take a look at http://docs.wand-py.org/en/0.4.3/ .

I've not used it myself, but I've had a few people I trust recommend it.

Yes, OpenImageIO comes with python bindings. We use them at Weta in python, C++,  Go, and command line form.

And yea, that output you are seeing from the ImageMagick binary is a warning on stderr
