Ross, thanks for pointing out!
I haven't found FOR-413 and I still believe this may be fixed in FOP, will try to investigate ... where is image scaling done in PDF output for image width? Anybody knows?
FOR-296 would be a Cocoon/Forrest solution for the problem if implemented, right. We still work around by resizing the images :-(
Cheers Johannes

Hi!
We have some difficulties with high images in PDF output. This is probably FOP related, maybe someone may forward mail this to their list, thanks!
Images higher than about 600px (basically part of screenshots) that are not scaled down because of width will produce errors: 1. FOPException: No meaningful layout ... 2. java.lang.OutOfMemoryError 3. endless swapping (if forrest.maxmemory is high)
The first one is still somewhat legible but the 2nd and 3rd take some time to discover. They happen e.g. if the image is enclosed in a table. See example code below. This happens for PNG and GIF images.
The only workaround we found usable is to decrease the height of the image upfront. Setting height="400px" works, too, but the HTML quality is very poor.
Since scaling for wide images works well I hope that there's a fix for this.
Shall I file a forrest bug for this?
See http://issues.cocoondev.org/browse/FOR-413 and http://issues.cocoondev.org/browse/FOR-296 and add any comments you have.
With respect to the latter (which you created by the way ;-) there was some recent talk on the Cocoon dev list about enhancements to the image generator to do scaling. I've not revisited to see if anything has been implemented.
