I have some slight doubts that the images produced via Mapscript are really interlaced. At least with standard tools like irfanview or Gimp they do not have the tag 'interlaced'. But they have it if I create it with Gimp and the interlaced option or if I create the image with shp2img. Maybe a bug of Mapscript.
The image is created using saveImage($tmpFileNameAbs, $map); this way normally all format options of the map file should be taken into account, but this might not be the case. A good test is also always if the image can be used for PDF printing: if it works then the PNG cannot be interlaced since FPDF does not support it and you get an error message telling you this. armin On 06/03/2008 20:16, Ivan Mincik wrote: > Yes there is interlacing effect, I can clearly see it when I open the > application for the first time.
