Re: [ccp4bb] X-ray diffraction image --> .jpg

[Jim Pflugrath]

A JPEG has fixed colors for the pixel values.  A diffraction image has to
use a viewer to convert the pixel values (counts) to a color.
One problem with just using a converter to jpeg is how to convert
intensities to color (i.e. computer display values).

A demo version of d*TREK is freely available.  It contains dtdisplay which
can display most known diffraction image formats (including Rigaku and ADSC)
and allow you to get what you want to see.  Then you can use a screen
capture.

I guess that one should have an option to output a TIFF or JPEG in
full-resolution of the detector for use with pixel peeping photo programs
like Photoshop.  There has not been much demand for such a program, but
maybe times have changed.

Subject: [ccp4bb] X-ray diffraction image --> .jpg

Hi everyone,

        Is there a free utility that can convert an x-ray diffraction image
collected with an ADSC detector to a standard image file format e.g. 
.jpg, png, etc.?  I'm looking for something more elegant than a
screen-capture that will yield a higher (graphics) resolution image. 
I'm sure someone must have done this, but I haven't been able to find one.


Thanks,
Andy Torelli
