URL: <http://savannah.gnu.org/bugs/?48484> Summary: gnuplot: printing figure into file results in mostly black image (Windows) Project: GNU Octave Submitted by: hardy Submitted on: Tue 12 Jul 2016 06:07:38 PM GMT Category: Plotting with gnuplot Severity: 3 - Normal Priority: 5 - Normal Item Group: Regression Status: None Assigned to: None Originator Name: Originator Email: Open/Closed: Open Discussion Lock: Any Release: 4.0.3 Operating System: Microsoft Windows _______________________________________________________ Details: This happens under Windows with the current Octave 4.0.3 release, installed via the official installer. Here is a little script to show the behavior: clear, close all graphics_toolkit gnuplot plot(1:10) print('test.png') I will attach the resulting png file. Doing this with Octave 4.0.3 results in a mostly black image with the correct axis labels. Doing this with Octave 4.0.1 produces a correct image file. So this is a regression. It might be due to the version change of gnuplot that is delivered together with the Octave Windows installer (see bug #48474). Printing a qt figure into a file works fine. Printing into a jpg file also results in the same black image. But printing into an emf image file works fine. (I haven't tested more image file formats.) Doing this with Octave 4.0.3 under Ubuntu linux works fine. (But my linux PC has gnuplot 4.6.4 installed.) _______________________________________________________ File Attachments: ------------------------------------------------------- Date: Tue 12 Jul 2016 06:07:38 PM GMT Name: test_gnuplot_401_Win.png Size: 14kB By: hardy <http://savannah.gnu.org/bugs/download.php?file_id=37825> ------------------------------------------------------- Date: Tue 12 Jul 2016 06:07:38 PM GMT Name: test_gnuplot_403_Win.png Size: 9kB By: hardy <http://savannah.gnu.org/bugs/download.php?file_id=37826> _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?48484> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
