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

[Thomas S. <t.s...@fz...>]

the hard limits for terminals which produce pixel graphics are based
on the graphics file format:
GIF: 2 Bytes unsigned for width and height, must be <2^16 (=65536)
PNG: 4 Bytes signed for width and height, must be <2^31 (=2147483648)

so there is no ~65k limit for PNG files. just check this with 'size
100000,100',
it should work. but you may run into memory problems with a large image
with reasonable aspect ratio, e.g. 100000*75000 pixels with 48bit each
require ~42GByte, this may cause problems...
