Units rehash
by Tavmjong Bah 05 Dec '14

05 Dec '14

Hi, I have been living, breathing, and even dreaming units the past couple of weeks. My understanding of what Inkscape does and what it should do has evolved over the time period but now I think it has pretty much solidified. I thank all those that have given feedback. I've tried to put all this knowledge at one place: wiki.inkscape.org/wiki/index.php/Units_In_Inkscape Conclusions: 1. There are only three attributes that matter: * The SVG root 'width' * The SVG root 'height' * The 'viewBox' Together they define a mapping of the real world to 'user units', in particular they define a scaling factor. Introducing an additional attribute 'svgUnit' is probably unwise. The document class should have a member function that returns the scale based on the above attributes. Note: the SVG spec allows non-uniform scaling and an offset which Inkscape handles without problem so a Geom::Affine should really be returned. 2. The user should be offered the possibility of changing these attributes in a simple way that makes sense to a non-expert: * Change page size: The 'width' and/or 'height' are changed to the new page size with the 'viewBox' changing to keep the same scaling factor. This is what Inkscape does now and has in the past. * Change page scale: The 'viewBox' is changed to set the a new scale factor (the page remains the same size). The GUI should offer the ability to pick a suitable scale factor (e.g. 1 mm == 1 'user unit') from a drop-down menu as well as allow the knowledgeable user to pick a custom scale by setting the 'viewBox' directly (via an expandable section that is normally hidden, like the as is done with the margin settings). Changing the scale factor will result in already existing objects (shapes, paths, text) changing size relative to the page. (Trying to keep the relative sizes constant is difficult and error prone except in the one possible case of wrapping all the content in a group and applying an inverse transform to the group.) With these transforms in mind, it is easy to see what should be done with the 90 dpi to 96 dpi transition. The main problem is for drawings of a specific size like A4 where the width and height are defined in pixels using 90 dpi. To 'fix' these files, change the width and height to use 'mm' or 'in' and then add an appropriate 'viewBox' to set the scale of the 'user unit' to 90 dpi. 3. Guides/Grids/3D Box Tool Guides, grids and the 3D box tool coordinates should be stored as 'user units'. This can be seen by the simple exercise of asking what one would expect to happen under the above transformations: Consider drawing a rectangle, duplicate it and then covert the duplicate to guides. As the page is resized and rescaled one expects the guides to stick to the rectangle's edges. Trunk already has code to define guides in terms of 'user units'. This code should be back-ported to 0.91. It should be relatively easy to handle the 3D box tool coordinates the same way. Grids are a bit more problematic because they allow (actually require) the use of unit identifiers (which are not allowed for guides and 3d box tool coordinates). If the unit identifier is not 'px' then there will be a problem between 0.91 (90dpi) and trunk (96dpi). We can offer an extension to make this conversion for grids and 3D box tool coordinates. Tav

is 48.5 changing?
by john Culleton 03 Dec '14

03 Dec '14

If I refer to inkscape 48.5 in a book about cover design, am I OK with using the current version of 48.5 or are there still changes being made? I update 0.91 nightly but not 48.5 However in the world of Scribus I update both 1.4.x and 1.5.0 nightly because changes are still being made in the "stable" product. -- John Culleton Wexford Press Free list of books for self-publishers: http://wexfordpress.net/shortlist.html Updated PDF e-book: "Create Book Covers with Scribus 1.4.5" coming soon at http://www.booklocker.com/!

Downloads Exception
by Martin Owens 02 Dec '14

02 Dec '14

Devs, Launchpad have allowed my request for a downlaods size exception to expire. (which I'm not happy about) But this does leave us with an important todo item, we must find a new home for our downloads before the 0.91 release because of the very unsafe nature that sourceforge has become. We do know these things: * Launchpad can only host our windows and source packages, Max OSX is too large. * Our website would not cope with our download traffic. * We have no mirrors, official or otherwise. If you have any ideas how we can solve this problem, please discuss here. Martin Owens,

Visual Align interaction proposal
by Jared Meidal 02 Dec '14

02 Dec '14

Hi Martin, I love seeing this alignment video reemerge, I'm looking forward to easier alignment on the canvas. Thanks for pushing for good UI for this. I recently tried out the newest Paint.NET and found their manipulation UI interesting. When moving a mouse cursor out on the edge/margin of an object the courser icon changes and rotation is possible automatically. Could something like this be a consideration if you are wanting to keep the number of layers of interaction (three click-cycles) down? Perhaps moving to the margin or waving around the cursor of a selection of objects would force a hovering alignment tool to appear? Just putting this out there as if you need more ideas. (I haven't seen Fernando's attachment that was scrubbed for me in the mailing list) --Jared

0.91pre3 crash on OS X importing of graphics
by Jared Meidal 02 Dec '14

02 Dec '14

I'm happy to see a dmg build for 0.91! Thanks for packaging this. So far I feel it is operating in parity of performance with the 0.48.5 X-11 app I've been using. Very glad to see the performance has not digressed. However I filed a bug because of the consistent crash I receive on two Yosemite Macs when attempting to import a raster file, or copy/paste from the desktop or GIMP. https://bugs.launchpad.net/inkscape/+bug/1398521 I'd like to see this be fixed before release, so happy to do any more package testing if needed. --Jared

Contest
by Jabier Arraiza 02 Dec '14

02 Dec '14

Hi to all. I get some interesting info about a contest to use Europeana Cataloge of art. Here are the link: http://pro.europeana.eu/web/europeana-creative/news/-/blogs/design-challeng… Im thinking on expand open-clip art import to allow europeana content. Im not sure if is allowed by licensing, etc. and if seems a good proyect to Inkscape. Also if anyone want to join on this proyect, specialy Open Clipart imports devs -sure i reuse a lot of code- are greatly welcome. Regards, Jabier.

remove of DPISWITCH extension from tunk
by Jabiertxo Arraiza Cenoz 30 Nov '14

30 Nov '14

Hello i want to remove the DPISWITCH extension from trunk. Why? I find displacements problems in clip-mask, -inverse displacement-. So because we are thinking to handle the DPI on export/print... If DPI is customizable on export, maybe is a good point to allow by default 96 but a free input box. Regards.
