Did anyone see something similar happen :
I use write_tiff to save arrays as true color image.

array_1=bytarr(512,512)
array_2=bytarr(512,512)
array_3=bytarr(512,512)
array_1[*,*]=255
array_2[*,*]=10
array_3[*,*]=10
WRITE_TIFF, 'test.tif',
RED=array_1,GREEN=array_2,BLUE=array_2,PLANARCONFIG = 2

Now, when I open the test.tif image with an image processing soft (PSP,
v4.0), the image size is 491*491 ! Saving a 512*512 byte array as a
grayscale image doesn't produce a similar artefact ! (I suppose the
problem does not come from IDL.)
