Re: [Gnuplot-info] looking for max terminal sizes for png, jpg, and other file output terminals

[Ben L. <be...@bl...>]

My png's were short and wide (500 pixels x 80k pixels x 4 bytes) so there were no real memory issues.

I was using html/php as a front end for my work and it turned out to be a browser limitation.

Thank you vary much Thomas.
