Re: [Qgis-developer] Raster colours
Hi all, I'm the maintainer of cpt-city, mentioned above. Perhaps of interest is the API for the full package of gradients. I quote API because it is really just an XML file which lists the current version and names of the package files -- the idea being that software which want to keep an up-to-date copy of the archive can check this file and download the latest version if it is newer than the version it has already.

Re: [Qgis-developer] Raster colours
Hi Paolo, Thanks for stepping in. This seems the way to go. As for the licences, are we OK including all your sources in QGIS? Any of *my* sources, yes (GPL or public domain), but the gradients on cpt-city are under various licences (as listed in the files COPYING.xml). Many of these licences do not permit 3rd party redistribution or contain conditions which would be incompatible with GPL etc. One could select a GPL compatible subset, but it would miss some of the best ones and take quite a bit of work (volunteers invited!) This is why I have implemented the user download-friendly API, so that users can avoid the hassle of downloading and installing the gradients if they have a bit of software support, without software developers redistributing the gradients themselves (something similar was done with the MS Core Fonts) Incidentally, if you were thinking of adding support for reading SVG gradients, then I have some C code which will do that http://soliton.vm.bytemark.co.uk/pub/jjg/en/code/cptutils.html (see src/common/svg*) all GPLv2, or you can have a copy under any reasonable free licence if you prefer Cheers Jim -- View this message in context: http://osgeo-org.1560.n6.nabble.com/Raster-colours-tp4991140p4992375.html Sent from the Quantum GIS - Developer mailing list archive at Nabble.com. ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer

Re: [Qgis-developer] Raster colours
OK will merge, unless someone dissagrees today. For the meantime, integration of this work with Arun's will be identical to other color ramps. It is based on the ColorBrewer ramps - the cpt-city color ramp dialog creates a new color ramp, after which it is available in the Style Manager. It could be better integrated with Arun's work by managing the available color ramps, instead of the saved color ramps.

[Qgis-developer] New Plugin - Edit Any Layer
Hi All, It seemed a little bit odd to me that QGIS is able to open many file types but you can only edit a couple of them. Being new to the world of GIS and therefore not understanding any of its history, this seemed as odd as photoshop being able to open but not edit jpeg files! In part of my work looking at adapting fTools / SEXTANTE to write to memory layer / any ogr format, I have created a standalone plugin that converts any vector layer to a memory layer (and therefore allows you to edit the layer). This plugin is hosted at [1], if you like I will move it to a more permanent location. Notes: * Filters for just vector layers (but could be further filtered to vector layers that cannot be edited in their current format). * No progress bar at the moment (at 1000's of features the plugin can take a little while so will add a progress bar at a later date).

Re: [Qgis-developer] SVG-Icons instead of PNGs?
Hi, Well, after lots more testing and head-scratching, I came to realize the QSvgIconEngine plugin was not being bundled with the Mac builds. This was why SVG icons were being rendered but scaled like rasters. This skewed my previous SVG icon Qt scaling test. Sorry for that. I've included the plugin for Mac bundling [0]. This changes my previous results in two ways: - I no longer see any issues with down- or up-scaling with any of the test SVG icons on Mac. - Robert's 24x24 SVG icons scale OK to 32x32. I have not tested the scaling up to 48x48. Since it is a straight 200% I expect it will render even better. To test up-scaling, I have reverted mActionPanToSelected.svg back to Robert's original 24x24 design [1]. Set the icon preference to 32x32 to test. Since my testing on Mac was not up-scaling SVG icons before I did not notice the issue with the Default theme's switched-out SVGs with embedded rasters. They are now up-scaling very poorly to 32x32, where such embedded rasters were originally PNGs at 24x24 (mActionPanToSelected and mActionRotateLabel). Second Test Conclusions - 48x48 base icon size would probably still be ideal as a single icon set base size, since it could be rasterized at that size (or lower) if PNGs are required for something. However, 24x24 base size may work well when scaled and rasterized (further tests needed here). - Embedding rasters in SVGs (for having Default theme available while moving to an SVG-only theme) is not a good idea. The rasters up-scale poorly. I suggest a clean move to a SVG-only set, if QSvgIconEngine is to be leveraged to solve scaling problems for core icons. PNGs could still be supported once the getThemeIcon() method is removed, since it currently chooses the icon based upon file name and extension.

Here's what I've done: - Several PNG icons were switched out with SVG counterparts to test Qt scaling on different platforms - Added SVG icons to Default theme that are comprised of the regular PNG embedded within - Added SVG icons to GIS theme, mostly @ 32x32 and one @ 48x48 (note: commit message is incorrect about 24x24) - Testing with the supplied GIS theme allows for contrasting against other similarly designed, preexisting PNG icons. GIS theme Icons to test (with document, or page, size and description noted): mActionPanToSelected.svg - @32x32 (Pan Map to Selection tool) mActionRotateLabel.svg - @32x32 (Advanced labeling Rotate Label tool) mActionSelectPolygon.svg - @32x32 (Select Feature by Polygon tool) mActionSplitFeatures.svg - @48x48 (Split Feature tool) To test: 1) Set your icon theme to Default. View whether each test icon looks as it did before. This will verify whether SVG with embedded PNGs of the original icons works with your version of Qt. (QIcon notes Qt 4.2 or icon engine supports SVG.) If we wanted to move to all SVG source files right now, this would provide an intermediate step for existing PNGs that don't have SVG counterparts. 2) Switch to GIS theme and individually test the above noted icons at the 16, 24, and 32 sizes. - Test mActionPanToSelected by viewing in main menu, and as a toolbar button - To test mActionRotateLabel, you will need a vector layer in edit mode, and with data-defined rotation column. View toolbar button. - Test mActionSelectPolygon by viewing it in the popup menu, main menu, and as a toolbar button. - To test mActionSplitFeatures, you will need a polygon vector layer in edit mode, with two features selected. Also view in Edit menu - Compare your results against mine [1]. Please share screen snaps of any different findings. My results on Mac, with Qt 4.8.1 and 4.8.2 [1]: - Overall IMHO Qt down-scaling is better than that of PNG. - SVG document size of 32x32 scaled to 24x24 (75%) showed some blurring. - Qt will _not_ up-scale SVG toolbar buttons when setting the toolbar's icon size, without doing so preprocessing first. SVG sources used by the icon engine appear to be rasterized at their document size, then later only scaled down when the icon size of the toolbar is adjusted (just like PNGs). So, starting with an appropriate 'largest' size for the SVG source seems to be key.

Yeah, happy to add it to the repo. I posted it here first to see if anyone had initial feedback. Will upload it in the next few days. Rob On , John C.

I would not categorize the ds9 collection - the palettes are all different.
The Color Brewer case is quite simple in my (perhaps
graphically-challenged) mind - group all the Blues_xx together, the
BuPu_xx together.
I am simply talking about variants of the same palette (with varying
number of colors) rather than classification, which can be arbitrary
as you point out.
GnBu_03, GnBu_04, ... , GnBu_09 = GnBu{_03,_04,...,_09}

Again, I am talking about groupping together palettes based on similar

Being new to the world of GIS and therefore not understanding any of its history, this seemed as odd as photoshop being able to open but not edit jpeg files! In part of my work looking at adapting fTools / SEXTANTE to write to memory layer / any ogr format, I have created a standalone plugin that converts any vector layer to a memory layer (and therefore allows you to edit the layer). This plugin is hosted at [1], if you like I will move it to a more permanent location. Notes: * Filters for just vector layers (but could be further filtered to vector layers that cannot be edited in their current format). Please don't restrict it like that. It is useful to be able to make a memory layer copy of even a layer that is writeable. You might even consider renaming it to reflect that - Copy as memory layer perhaps? What would be useful is an option to only copy the selected features. And it should work even with no selected features - this would provide a quick way to create an empty memory layer with the same attribute columns. * No progress bar at the moment (at 1000's of features the plugin can take a little while so will add a progress bar at a later date). [1] http://ubuntuone.com/3Zl1ojo3ZMUJxMqj2kcZaX Regards, Rob Nice plugin - good work!
