The projection parameters: category=UTM,System=Zone 31 N, Datum=WGS1984. When I re-import it in didger, I can’t have the same coordinate. I didn’t changer the projection parameters when I import it. I can reproduce the problem where the coordinates are slightly different from exporting a WMF file and importing it again. I will forward it to programming. Another probleme with the format /EPS/. I have exported a map from arcview en format EPS and I can edit all objets in corel draw by using the command dissociate, but when I exported a vector image from didger en format EPS, that’s a raster image, I can’t dissociate it in corel draw.I would like to know it’s normal or I have done somthing wrong? You did not do anything wrong. The EPS files that Didger exports are raster-based. I will add your vote to the request on the suggestion file for Didger to export vector EPS files. Source.
