Hi Mathematicians, are there any limitations as far as the size of an image is concerned to be used with the warp-algorithmus [ImageWarp] as implemented in the digital imaging add-on? There is no problem using it for small images, but for bigger ones (i.e. 1028 x 808) error messages like CompiledFunction::cfn : Numerical error encountered at instruction 34; proceeding with uncompiled evaluation which leads finally to: General::stop : Further output of CompiledFunction::cfn will be suppreessed... And my second question: Because I don't have any ideas on the warping algorithm used: For more complicated warpings is it necessary using some special sequences of the points concerned? Thanks a lot for each hint Harald -- Harald von der Osten-Woldenburg Geophysical Prospection of Archaeological Sites Landesdenkmalamt Baden-Wuerttemberg Silberburgstrasse 193 D-70178 Stuttgart Fax Office: +49-(0)711-1694-707 Fax Private: +49-(0)180 50 52 55 22 10 05 http://www.lb.netic.de/hvdosten/index.html: Geomagnetics and Geoelectrics http://www.region-lb.de/HomeSites/HvdOsten: Ground Penetrating Radar and EMI
