URL: <https://savannah.gnu.org/bugs/?54693> Summary: Qt/FLTK - export as PNG - wrong image size and aspect ratio Project: GNU Octave Submitted by: None Submitted on: Wed 19 Sep 2018 02:43:30 PM UTC Category: Plotting Severity: 3 - Normal Priority: 5 - Normal Item Group: None Status: None Assigned to: None Originator Name: aj Originator Email: Open/Closed: Open Discussion Lock: Any Release: 4.4.1 Operating System: Any _______________________________________________________ Details: Exporting a figure from Qt/FLTK results in an image with incorrect size and aspect ratio. This does not seem to happen with Gnuplot. Tested on Arch Linux and Windows 7 with Octave 4.4.1. Example code is shown below and example results (exported images and screenshots) have been attached. Qt and FLTK seem to produce identical results. xdata=[0:0.01:4*pi]; ydata=sin(xdata); plot(xdata,ydata); _______________________________________________________ File Attachments: ------------------------------------------------------- Date: Wed 19 Sep 2018 02:43:30 PM UTC Name: plot_image_FLTK.png Size: 16KiB By: None <http://savannah.gnu.org/bugs/download.php?file_id=45051> ------------------------------------------------------- Date: Wed 19 Sep 2018 02:43:30 PM UTC Name: plot_image_Gnuplot.png Size: 7KiB By: None <http://savannah.gnu.org/bugs/download.php?file_id=45052> ------------------------------------------------------- Date: Wed 19 Sep 2018 02:43:30 PM UTC Name: plot_image_FLTK_screenshot.png Size: 25KiB By: None <http://savannah.gnu.org/bugs/download.php?file_id=45053> ------------------------------------------------------- Date: Wed 19 Sep 2018 02:43:30 PM UTC Name: plot_image_Gnuplot_screenshot.png Size: 40KiB By: None <http://savannah.gnu.org/bugs/download.php?file_id=45054> _______________________________________________________ Reply to this item at: <https://savannah.gnu.org/bugs/?54693> _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
