@erikvanberkum, I've merged your question from general support to the support thread of the FieldtypePDF module. You may also want to open an issue about this in the FieldtypePDF GitHub repository. Also, please make sure that you're running the latest version of the module ?

It seems like I have a colour depth issue when trying to generate an image from an uploaded PDF file. Any clues how this can be corrected? Thanks.

Hi @kalimati, not exactly sure, but I guess it will be related to the colorspace the PDF is in? 🤔 I am no expert on this area and don't know if PDF can have different colorspace, but the field has an option to set the colorspace to be used for the image generating (on Details tab), so you can experiment with it. 

 

You can also check https://github.com/uiii/ProcessWire-FieldtypePDF/blob/9f07314883cd281e09851f149b8889c1a3e8daa0/FieldtypePDF/PDFConverter.php#L149 where is the code to generate the image, and you can find a way how to use ImageMagick to generate image for your PDF, we may reflect it in the code after.

@kalimati Also this looks useful https://imagemagick.org/discourse-server/viewtopic.php?p=80210&sid=88e589266091f18cef53b8adc6a4d0b1#p80210 Try to identify the colorspace, this way it would be useful to detect the colorspace in the code if possible.

Thanks for your reply, Richard.
I don't see the ImageMagick settings (advanced) in my installation. I am using Processwire 3.0.229 and module version 1.1.5 on Ubuntu with PHP 8.1.

It is in the field settings (Details tab) not the module settings.
