[Octave-bug-tracker] [bug #45881] Diagonal lines visible in PNG image created using pcolor

[anonymous]

Follow-up Comment #3, bug #45881 (project octave):

This is a ghostscript wrapper that solves the problem


#!/bin/bash

ARGS=()
ARGS+=("-dGraphicsAlphaBits=1")
for var in "$@"; do
        [ "$var" != '-dGraphicsAlphaBits=4' ] && ARGS+=("$var")
done
gs "address@hidden"


It basically turns of anti-aliasing for graphics but it is a hack. It should
also be added that the gnuplot backend is also affected.

This bug is similar to the infamous `sound` bug. The bug here is that
ghostscript cannot be used to rasterize the vector graphics. With the MESA
support in 4.0, it is perhaps possible to render to a file directly, without
an external program.
