Slow conversion for some files

[mmettey]

Hi,

I've found some performance issue when converting a specific file today.
It took about 300 seconds to convert this one page PDF to SVG, using CLI :

page5.pdf

This one is part of a 124 pages PDF, and every page of this full document is converted slowly, but this page is the slowest one.
I tested with pdf2svg library, and for the same file it takes 2 seconds.
Is there anything in that PDF file that is increasing processing time in pdftosvg.net ?

I tried to optimize the document with Adobe before conversion, but it doesn't help. The only thing that helps is to rewrite the PDF file with Ghostscript, but I'd like to avoid this.

Thanks in advance for your help !

Thanks for reporting this issue. The performance has been improved in version 1.6.0.

The PDF format supports many types of gradients, where some of them are not supported in SVG. For those types, PdfToSvg.NET will render them as raster graphics. In this case, the raster graphics were rendered at a too high resolution for how they were used. Version 1.6.0 will render them at a lower resolution where appropriate.
