CreateImageFromDIB Method

Hi,

I need the opposite of this method.

I have to pass the handler of a DIB to an OCR control that can handle only file or DIB handler (and i don't want to use a file).

So there is a way to get an handler of a DIB structure created from current GDPicture image ?

Like CreateDIBFromImage :)

You know if there is some way to get the exact DPI corresponding to this enumerator (i mean... Draft quality how many DPI is ??). I suppose that is depend on printer driver...

[For Sarzan] Hi Sarzan, I got your image. It is a special image because the first line of the top of your image are not totaly white... The autocrop algorithm consider it not like a white band so it doesn't want to remove it. The better way with this kind of image is to use the CropWhiteBands metho...

Hi Loic, In the meanwhile i implement an "hand made" routine to do the crop on the same image. The routine work fine and use gdPicture object with same "confidence" level of the .Cropborder2 routine.
