Convert pdf command issue with colors

[b-ilic-levi9-com]

Hi,

We are developing solutions for our client, that includes usage of MuPDF.NET library and two functionalities – recolor and convert to pdf functions.
Our license and engineering code is 370.

If we convert attached svg file, converted pdf won't have any colors (it will be in black and white).
Do you have an idea what could be causing the issue?

Here are also code snippets how we are using the recolor and convert methods.

private byte[] ConvertCommand(byte[] byteArray)
{
var muPDFDocument = new MuPDF.NET.Document(stream: byteArray);
return muPDFDocument.Convert2Pdf();
}

private byte[] RecolorCommand(byte[] byteArray)
{
var muPDFDocument = new MuPDF.NET.Document(stream: byteArray);
muPDFDocument.Recolor(0, "CMYK");
return muPDFDocument.Write();
}

Kind regards,
Bojan

This is not a Mupdf.net related issue:
When executing the base library's CLI command the resulting pdf os grayscale as well, e.g. mutool convert -o test.pdf test.svg.

So we need to pass this on to MuPDF's issue system.

Thanks for your confirmation.

Yes, good spot, I checked out the SVG in a text editor and could see the class references, did a find and replace on those to replace with fill= and ran the file again. Then it retained the colors faithfully. We will report this issue upstream to the core MuPDF team. However, I suppose it could be theoretically possible to do a find and replace in code for class= to fill= and try to match the colours for the data within the file?

I attach my SVG which I modified.
