Follow-up on #11 -- Goocanvas issue? ============================== http://developer.gnome.org/goocanvas/unstable/goocanvas-coordinates.html -- Coordinate Limits
<< GooCanvas uses the Cairo graphics library to render canvas items. For performance reasons Cairo uses 32-bit fixed point integers internally when rendering graphics, with 24 bits used for the integer part of values and 8 bits used for the fractional part. This means that values are limited to roughly +/- 8,388,608. >> Since there is also a decimal part on 8 bits, which encompasses the range from 00 to 99 (but not to 999), Goocanvas can work with coordinates ranging from -8,388,608.00 to +8,388,607.99 . Assuming that a desired time-line precision would be 1/100 sec, Goocanvas should be able to accommodate a time-line of 16,777,216 seconds, which is ... 4660 hours (and a handful of additional minutes, around 20)!! And even if one wanted to go for a 1/1000 sec precision, Goocanvas would accommodate a time-line of 466 hours. The 2-hour video projects that we are speaking about should fit in, couldn't they? -- You received this bug notification because you are a member of UBUNTU - AL - BR, which is subscribed to OpenShot Video Editor. https://bugs.launchpad.net/bugs/722285 Title: timeline only shows 320 times the zoom slider setting Status in libcairo - cairo vector graphics library: Confirmed Status in OpenShot Video Editor: Confirmed Bug description: The timeline only shows the first (320*zoom seeting) seconds of a project. So if the zoom slider setting is set to 1 s, the timeline stops at 5'20'' (=320'') if it set to 2 s, it stops at 10'40'' (=640''), 4 s it stops at 21'20'' (=1280''), etc. How to reproduce: -launch OpenShot and create a new project of 60 min -with the default 8 s zoom setting you can only move the timeline up to 42'40'' (=2560 = 320*8) -try zooming in and see the timeline shorten as you zoom more 1.
