Exporting Graphic as 16 Bit

Share icon

I'm having trouble exporting a graphic as 16 bit. I'm using SavePICT with /D (whole bit is SavePICT/E=-6/RES=200/D=16). However the file that pumps out always seems to be 8bit (opened with other program). I've tried using D=1,8,16,24, and 32 and the size of the file is always the same after export, shouldn't it get larger with increasing bit size?

Please note that it would be helpful if you specify which version of Igor you are using.

/E=-6 is a JPEG file. JPEG files are not supported in any bit depth other than 8-bit/sample. If you need 16-bit output consider using TIFF format.

Hi,

I've tried in both IP6(.37) and IP7. I switched to SavePICT/E=-7/Res200/D=16. No Difference though. It always saves the graphic as 8bit. I Switched to ImageSave. That worked.


Thanks for the details on jpg. I didn't know that.
