Dear All,

I am using mapfish to print WMS layers from Geoserver 2.4.0. While printing WMS layers, Error appears in PDF file for some WMS layers.

The Error is:

java.io.IOException: The byte array is not a recognized imageformat.

If I am using the format “application/pdf”, everything is printed correctly but quality is very poor.

I am using below code to get print:

http://localhost:8080/geoserver/pdf/print.pdf?spec={

    items:
  • !map
    width: 500

A complete stab in the dark here, but does it work when you remove the backgroundPDF from the config.yaml?

Although if it only happens with some WMS layers you say? Are you sure the WMS requests that MFP is sending are actually being responded to with images and not exception reports? Might be worth trying them as stand-alone URL’s.
Cheers,
