Vectors are good - just wasn't sure what you were trying to accomplish. The problem is that you've exceed the maximum size of a standard PDF page (200in in each direction). You can try using the UserUnits key on the Page dictionary to extend the page size large enough for your content. You can try to apply an appropriate CTM in order to get it to render correctly. You can break it across multiple pages.

We know that the exported vector graphics have indeed very strange dimensions, but this is intended, since this is the figure of a data matrix with 40 columns and about 6000 rows. Other pdf viewers display the figure as expected. We want the figure to be vector graphics for further scaling or printing. Do you suggest to combine it with raster data (is it even possible? how would this work?)? Thanks Jan Concerning the "imageConsumer": This is just a class providing a Java Swing Component and a dimension.
