[ccp4bb] [SUMMARY] X-ray diffraction image --> .jpg

[Andy Torelli]

To the CCP4 community.

	As always, I have received a number of very helpful suggestions to my 
query.  I am grateful to all those who replied.  My best summary of the 
suggestions is below.

Best Regards,
-Andy Torelli

	A notable consideration (provided by Jim Pflugrath) is that "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)."
	Additionally, Morten Kjeldgaard noted that opening saved images 
(particularly TIFF images) in Photoshop will require "Image -> 
Adjustments -> Equalize" to see anything other than black.

Specific program suggestions:

 - diff2jpeg - a CCP4 utility within the "DiffractionImage" library for 
handling different diffraction file formats.  See: 
http://www.ccp4.ac.uk/html/DiffractionImage.html

 - idiffdisp - a CCP4 utility.  See also CCP4wiki page: 
http://ccp4wiki.org/~ccp4wiki/wiki/index.php?title=CCP4i_diffraction_image_display_%28idiffdisp%29

 - ipdisp - a CCP4 utility.  See also:
http://www.ccp4.ac.uk/dist/html/ipdisp.html

 - Mosflm has capability including control over gr[e|a]yscale.  See FAQ 
section for details.

 - ADXV - reportedly easy to install and can save in TIFF format.  Also 
will save image to match coloring in view window:

 - Marview - can be installed using Linux_glibc-2.3.3 (RedHat9, WS3, 
etc).  Just download it, unpack (gunzip marView.gz).  See also 
http://www.marresearch.com/download.html#Utilities
        # chmod a+x marView

        a) to run the program from terminal
        # ./marView     or

        # kate .bashrc:
            alias marview=/home/user/Desktop/marview/./marView

	b) alternativelly, place the program in the Desktop and just 
double-click to start it up.

 - demo version of d*TREK is freely available from Rigaku and has 
dtdisplay for this purpose.

 - Labelit - see http://cci.lbl.gov/labelit

 - ImageMagick - part of most linux distros.  See also James Holton's 
helpful and detailed reply to my original post.
