[Scilab-users] GIF with transparent color
Hello, I'm creating contour plots and it would be nice to have certain regions (colors) of a GIF file transparent. Is that possible with SCILAB? Thanks in advance. Best regards Wolfgang ___ users mailing list users@lists.scilab.org http://lists.scilab.org/mailman/listinfo/users

You've got a filled or fill_mode attribute for every object. You should set it to "off" for given objects. See for example http://help.scilab.org/docs/5.4.1/en_US/axes_properties.html Hope this helps. -- Christophe Dang Ngoc Chan Mechanical calculation engineer __ This e-mail may contain confidential and/or privileged information.

I am afraid that not, not directly. May be post-processing an export through Java from Scilab? Java has so many libraries... You may post a wish on bugzilla. PNG format may also support a transparent color. Samuel ___ users mailing list users@lists.scilab.org http://lists.scilab.org/mailman/listinfo/users

Best regards Wolfgang ___ users mailing list users@lists.scilab.org http://lists.scilab.org/mailman/listinfo/users Hi Wolfgang, I don't have a solution, but might propose a workaround: why don't you replace a certain range of values (those that you want transparent) by %nan? If I remember correctly, this should open a hole in the filled contour plot. Hope it helps, Antoine ___ users mailing list users@lists.scilab.org http://lists.scilab.org/mailman/listinfo/users

By the way, as far as i know, GIF and PNG allow to define only /one/ transparent color. So, if you want several regions of distinct colors of the same plot being transparent, PNG and GIF would not allow that. I don't know any other common image formats able to do that. If you are looking for transparency of the foreground in order to see the figure's background instead of the image's one, tricks given by Christophe and Antoine will certainly work. In the end, you may have a look at /help pixel_drawing_mode/ . This feature for instance used to help plotting stacked objects without hidding stacked parts. But Scilab 5.4 has killed it : http://bugzilla.scilab.org/show_bug.cgi?id=12017 Best regards Samuel ___ users mailing list users@lists.scilab.org http://lists.scilab.org/mailman/listinfo/users
