Hi, what do you think about the way the size of the gradient should be set (in the future)? I came up with 4 ways: 1. Edit-Box for width and height width/height is set in percentage 2. Edit-Box for width and height width/height is set absolute (mm,cm,inch,...) 3. Edit-Box for width and height width/height is set as a dot seperated value -> 1.0 would be the same width/height as parent width/height 4. NO Edit-Box for width and hight handles on the gradient(on canvas) are used to change the size (the Edit Boxes can be seen in my mockup I sent in the first mail) <a href="http://temp-share.com/show/f3Ygit6Xn">http://temp-share.com/show/f3Ygit6Xn</a> My opinion 1. cause the size of the gradient can be bigger then the parent's the value would become bigger than 100% ->weird 2. if the size is changed and one want to set it to the parent's size it's not that simple (unless there is a reset button) 3. ok, 1,0 would be the same size as the parent's 4. cause in my opinion Draw is mostly used to draw simple stuff the handles may confuse some people and it may be harder to implement (although I would like this option as well, cause that's the way Inkscape does it) btw. should the Border Edit Box(in the gradient tab) be replaced with a width/height Edit Box? I think if one can set the height and widht the border Edit Box becomes obsolete??? where can I get the latest snapshot of AOO is this one ok?: <a href="https://cwiki.apache.org/OOOUSERS/development-snapshot-builds.html#DevelopmentSnapshotBuilds-AOOSnapshotfullsets">https://cwiki.apache.org/OOOUSERS/development-snapshot-builds.html#DevelopmentSnapshotBuilds-AOOSnapshotfullsets</a> I use the LO version from here: <a href="http://dev-builds.libreoffice.org/daily/">http://dev-builds.libreoffice.org/daily/</a> On 04.06.2013 at 11:31 PM, "Andrea Pescetti" <pescetti@apache.org> wrote:<blockquote style="border-left:solid 1px #ccc;margin-left:10px;padding-left:10px;">Forwarding Armin's and Regina's answers, below, to the original poster. bugreporter99: please follow <a href="http://mail-archives.apache.org/mod_mbox/openoffice-dev/">http://mail-archives.apache.org/mod_mbox/openoffice-dev/</a> to read answers (or subscribe to this list, same link).
