Dear Hanna,
each call to rlpoin writes a rect fill tag to the SVG file with nearly 80 bytes for each call. I think that
you have about 50 millions of rlpoin calls in your program for creating a 4 GB SVG file.There is
no routine in Dislin that you can use instead of rlpoin for reducing the size of the SVG file. Perhaps,
you can create an image format such as PNG, where the size of the PNG file is independently from the
number of rlpoin calls, or from any other plot vectors. It's also easy to include a PNG file into a SVG file
with the image tag.
With best regards,
Helmut
