Size of svg file

[Hanna Liashenko]

Hello, Helmut. I have one problem with creating svg file. The graph in svg format is very large (about 4 GB). I use rlpoin for create point in graph and there is a big number of points. And I think it is the problem with size (big data array). Use curve(for example) i can't, because each point should have different color and form(depending on the value). How it is possible to solve it?

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

Thanks for your help, Helmut!

My tool should create png, svg and jpg format, use for it only DISLIN or standard C++ library. It's a small challenge. But idea with including a png into svg - very helpful. I'll try it.
