Hi Joost,

About the white bitmap, this usually happens if there is a problem reading the graphic from the file. I am really not sure on how the ScanLinep property helps with the memory leak you are encountering. If you really want to access the raw data without even loading the data in a TDibGraphic, look at EnTifGr.Pas, SingleLoadFromStream. You should be able to figure it out from there to load just the raw tif data in any structure you want.

For version 1.1, I cannot maintain both version, but if you email me (michel@intervalsoftware.com) I will send you the latest EnDiGrph.Pas which you may need to adapt slightly to work in version 1.

Best regards,
