Re: Is it possible to Get back the original Image?

Hi Guru, I have seen, that nobody has replied to any of your posts - terrible :( So I will try to help a little bit. When you reduce the colordepth you have lost all informations about the original image, so you have no chance to get it back. Also the most compression-types are not lossless. What ki...

Nikon RAW is not using whitebalance information of the .nef

we are using Version 10 of GDPicture.NET. Opening a Nikon RAW file (CreateGdPictureImageFromFile), the result doesn't look fine. It seems that informations of the .nef file like whitebalance etc. are not used to show the image. in the preview of Windows and other Image-Viewer the file is looking muc...

ThumbnailEX not using EXIF Orientation Flag

The thumbnailEX does not rotate a thumbnail depending on the given EXIF flag of a JPEG-file. Most of digital cameras only give you the EXIF orientation flag to rotate the JPEG file in the right way. For an example, the Windows Explorer is able to show the thumbnails ok, but with ThumbnailEx it is ro...

TIF wrong Resolution

Hi Loïc,

after loading a TIF File (300 DPI) with CreateGdPictureImageFromFileICM and saving the File with SaveAsTIFF, the File has a wrong resolution (120 DPI). What I'm doing wrong?

Thanks forward,

TIF Tag Orientation

Hi Loic,

the Tiff Tag "Orientation" seems not to be supported in the GDViewer. DisplayFromFile is not using the flag to show the image in the right direction. :?: :!: :?:

Re: Using in 64bit app

Hi Loïc, hi edlemus,

most of new graphic boards can't work with the /3GB option of XP. In some cases you get a bluescreen. Using two monitors, you can get many trouble with the /3GB option. I'm looking for a solution for this problem.

Best regards,
Harry
