PI defaults

[tloebl]

Hi,

two issues...

I use fit format and 16 bit sample format. I have used (Global preferences/File I/O settngs) to change the default file-type from XISF to FIT but when I process images the file option still pops up as XISF and I have to manually change each option to FIT.

Also the sample format keeps defaulting to 32 bit floating point. Is there a place to change that to permanently default to 16 bit integer?

Thanks,

Tom

Hi Tom.
If you want to save an image that has 32bits bit depth, it will load that as default  when trying to save. Is that the case?

Hi Carlos,

my imaging is all 16 bit (65k) and am looking to always use 16 bits to work on images. I'm wondering if there's an option that allows all work to default to 16 bits rather than my having to choose 16 bits each time from the default  32 bits.

Tom,

Unless its a matter of system memory, you are always better off working in 32 bit floating point during processing, otherwise you risk losing a lot of detail (images often expand well beyond 16bits during processing).  You can always convert the final image to a 16bit TIFF or JPEG once you are done processing.

Best,

Jim

Hi Jim,

thanks for the suggestion.  I'm running an I5/16Gb and saving to my server so I should gave enough memory to deal with it. I suppose I can work with 32 bits and XISF format and save to 16 bit fit. I'll give it a go.
