FileSize when saving TIF/JPEG
Hi (again ),
Filesizes when saving TIF/JPG are 2-3 times the size we are used to.
Are you planning to support more options for TIF/JPG (Photometric & ColorSpacings?),
Look at the output for the following file:

Re: FileSize when saving TIF/JPEG
Hello,
We are already working on this YCbCr color saving for JPEG in TIFF. I think you should expect to get this option within GdPicture 10.1 or 10.2.
With best regards,
Loïc

That would be very nice.
(also in multiformat multipage tif files i assume?)

Yes also in multipage. The feature will be available next week.
Kind regards,
