Hi Robert! In fact, it was the same for me. That's why I used the setScale() method to resize the print preview. I don't know why this problem appeared. It's quite strange! Here is the code sample:
printPage.setScale(printProvider.scales.getAt(2)); //In my yaml file, the second scale is for the 1:300 000 I hope it will help. But no explanations! :s Geoffrey On Wed, 24 Aug 2011 09:03:59 +0200, Robert Buckley <robertdbuck...@yahoo.com> wrote: > Hi, > > after reading your mail I tried out the printpreview code in a test app. > This is > something I have been meaning to do for a while now but haven´t had the > time. > > Anyway, I copied the code from the printpreview example > (http://api.geoext.org/1.0/examples/print-preview.html) > > and set an osm baselayer to see whether my config.yaml file works with > OpenStreetMap.
