[Freeciv-Dev] [bug #20534] Worklist glitch: unit icons bleed past their boundaries
Follow-up Comment #3, bug #20534 (project freeciv): My guess would be you're hitting following documented case: When the destination rectangle contains parts not in the source image, the data at the edges of the source image is replicated to infinity. (documented for instance here https://developer.gnome.org/gdk-pixbuf/2.22/gdk-pixbuf-scaling.html#gdk-pixbuf-composite) Thanks, yes, that's almost certainly it. So the trick is to avoid doing that. ___ Reply to this item at: http://gna.org/bugs/?20534 ___ Message sent via/by Gna! http://gna.org/ ___ Freeciv-dev mailing list Freeciv-dev@gna.org https://mail.gna.org/listinfo/freeciv-dev

Follow-up Comment #2, bug #20534 (project freeciv): Going deeper into the code, it could hint to a problem with gdk_pixbuf_composite in canvas_put_sprite, but hard to tell without more testing. My guess would be you're hitting following documented case: When the destination rectangle contains parts not in the source image, the data at the edges of the source image is replicated to infinity. Unless there an off-by-one somewhere in that gdk-pixbuf code. ___ Reply to this item at: http://gna.org/bugs/?20534 ___ Message sent via/by Gna! http://gna.org/ ___ Freeciv-dev mailing list Freeciv-dev@gna.org https://mail.gna.org/listinfo/freeciv-dev

URL: http://gna.org/bugs/?20534 Summary: Worklist glitch: unit icons bleed past their boundaries Project: Freeciv Submitted by: jtn Submitted on: Tue Feb 19 22:47:35 2013 Category: client-gtk-2.0 Severity: 2 - Minor Priority: 3 - Low Status: None Assigned to: None Originator Email: Open/Closed: Open Release: Discussion Lock: Any Operating System: GNU/Linux Planned Release: ___ Details: This is very cosmetic, but it's been bothering me for years. In the worklist, unit icons which have pixels set at their vertical edges have those pixel columns bled out into bands horizontally. See attached screenshot of Freight, and also bug #15777's file #8785 for a previous example. In Amplio/2 I think unit icons are a little narrower than building/wonder icons, which force column width; I'm guessing that something is extending the unit icon to match the containing cell in a sub-optimal way. Really we just want whitespace padding. Dunno if this is specific to OS (Ubuntu 10.04.4), window environment (GNOME, Compiz), theme (Freeciv for client, Ambiance for desktop), ... It's been with me with the gtk2 client for at least three years, probably longer. ___ File Attachments: --- Date: Tue Feb 19 22:47:35 2013 Name: worklist_glitch_freight.png Size: 10kB By: jtn Glitch in city worklist, trunk r22387 http://gna.org/bugs/download.php?file_id=17267 ___ Reply to this item at: http://gna.org/bugs/?20534 ___ Message sent via/by Gna! http://gna.org/ ___ Freeciv-dev mailing list Freeciv-dev@gna.org https://mail.gna.org/listinfo/freeciv-dev

Follow-up Comment #1, bug #20534 (project freeciv): (FWIW, my previous notes on the issue in their entirety: client/gui-gtk-2.0/wldlg.c:cell_render_func(). Make of that what you will.) ___ Reply to this item at: http://gna.org/bugs/?20534 ___ Message sent via/by Gna! http://gna.org/ ___ Freeciv-dev mailing list Freeciv-dev@gna.org https://mail.gna.org/listinfo/freeciv-dev
