Generating PDF labels.

1) Start with diffraction pattern diffpattern2s1.jpg
   Scale it to be 732x732 pixels:
     mogrify -scale 732x732 diffpattern2s1.jpg
   Use gimp to set it to 150 pixels/inch
   Use gimp to erase center hub space
   
2) (0,0) is UL corner. 
   cp diffpattern2s1.jpg tests2.jpg
   
  mogrify -draw 'text 200,200 "starts at 200,200" ' tests2.jpg 
  draws text starting in UL quadrant
  mogrify -pointsize 24 -font Arial.ttf \ 
      -draw 'text 100,240 "Arial.ttf" ' tests2.jpg
  sets pointsize! 
  
2.5) Build an image which must be annotated by text:
a. create a 722x722 jpg with white background and big blue disc
     convert -size 722x722 xc:white -stroke lightblue -fill lightblue \
             -draw 'circle 361,361 0,361' mask1.jpg
b. create a slightly smaller black disc inside it, leaving a blue rim
     mogrify -fill black -draw 'circle 361,361 3,361' mask1.jpg
c. Create a blue disc in the center, where the hub will be, with a slightly
   smaller white mask inside.
     mogrify -fill lightblue -draw 'circle 361,361 436,361' mask1.jpg
     mogrify -fill white -draw 'circle 361,361 431,361' mask1.jpg
d. Combine the diffraction pattern or other image with the mask
   to make base1.jpg, the template to which we will add text
     composite -compose Plus dp2.jpg mask1.jpg base1.jpg



3) diffpat-masked.jpg is the image template to which we will add stuff
   perl script to use mogrify to add annotation file to image file
   usage:
     buildlabel1 annotation_file template.jpg annotated.jpg
     annotation file is in form:
       x,y^size^color^font^text 
         x,y   -- offset in pixels (150px/in) from UL
	 size  -- pointsize of font
	 color -- eg, red, blue, plum, black
	 font  -- eg, Arial, Helvetica, Times, Candice, Ravie, Gecko
	              (I don't know what else)
   Using command of the form:
     mogrify -pointsize 14 -fill blue -font Candace \
       -draw 'text 50,360 "middle of disc"' tests2.jpg	 
   (font spec does not work in this form)

4) Add the fixed part of the label:
  ./buildlabel1 xray-label-fixed-01.ann base1.jpg test1.jpg
  
5) Add the variable part of the label
    ./buildlabel1 example1.ann test1.jpg ex1.jpg
  Re-apply the mask:
    composite -compose Plus test1.jpg mask1.jpg test1f.jpg
  Convert to PDF
  convert  -density 150 -units PixelsPerInch test1f.jpg test1f.pdf

6) When sendinf test1f to elijah to be printed, use binary ode for the ftp
transfer.
