Description Stef Walter 2012-09-19 12:04:01 UTC
Description of problem:

When booting up Fedora 18 Alpha boot.iso, and selecting the 'DATE & TIME' option, the map of the world is blurry, and looks scaled up. It seems that a higher resolution or resolution independent version should be used.

Version-Release number of selected component (if applicable):

Fedora 18-Alpha install CD

How reproducible:

Every time.

What is the resolution of your display?

Comment 2 Stef Walter 2012-09-21 08:57:34 UTC
It is a VM, running at 1024x768.

Screenshot of the blurry map

Here's a screenshot. All the sea borders are blurry. See the islands in the north for clear examples of the blurriness.

We are using the same map widget as gnome-control-center, which uses PNG images. I'm affraid there are no images with better resolution available. However, I'm quite sure these PNG's were exported form SVG's, so I'll try to search for the source.
Scaling doesn't seem to be an issue to me.

Comment 5 Fedora End Of Life 2013-12-21 08:53:49 UTC
This message is a reminder that Fedora 18 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 18. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '18'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 18's end of life.

Thank you for reporting this issue and we are sorry that we may not be 
able to fix it before Fedora 18 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior to Fedora 18's end of life.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Anaconda uses libtimezonemap now for the map widget, but the map still uses the same set of PNGs. There is an SVG source now, though, so there might be a way to fix it to scale better.

Comment 7 David Shea 2015-08-28 19:55:21 UTC
I don't really think it's worth changing anything for this.

I just tried anaconda with the latest libtimezonemap images on a high-dpi 2880x1800 screen to see how it looks. It doesn't look great, but it's ok. The lines aren't sharp, and as for the specific blurriness you're seeing, well, that's actually in the source. That's what inkscape does when exporting the lines from the SVG.

The images are already about 4MB at their current size, and I don't think switching to SVG versions would help: the SVG is huge, and I've been told before by gtk maintainers to avoid SVG for both performance and stability reasons.

If you'd like to start a discussion with the upstream maintainers of the map, they're at https://launchpad.net/timezonemap
