Hi Stefan 1 vector: only translation 2 vectors: translation, scale and rotation 3 vectors: translation, scale, rotation and shear
I will add a page on the wiki about the usage (and the limits). Regarding including adjustment calculations, it requires probably more space and panels than the small Afine Transformation plugin. It is in my list to have a dedicate raster plugin with more options (dx and dy calculation and a perspective transformation of the image) Peppe 2015-06-18 18:30 GMT+02:00 sstein <sst...@geo.uzh.ch>: > Hi Peepe, > > sounds like a nice feature! 1 vector means translation only, or? > > With three i guess you need to inlude adjustment calculations as eg QGis > does in the georeferencing tool. > > > > How about making a little blog post? > > > > cheers, > > stefan > > > ------ Originalnachricht ------ > *Von: *Giuseppe Aruta > *Datum: *18.06.2015 11:23 > *An: *OpenJump develop and use; > *Betreff:*[JPP-Devel] Experimental Raster affine transformation on > OpenJUMP > > > Hi all, > I added to PlugIn *Tools-Warp-Affine Transform (from warping vectors)* an > experimental capability to do an affine transformation on raster images > (only loaded via Sextante Raster framework, not single band raster). > This capability uses JAI WarpPerspective.class to perform a buffered Image > transformation (see the code inside the class public static void > affineTransformRaster ). > How to use: a) Draw maximum 3 warping vectors b) Select a Sextante raster, > c) apply the plugin > The plugin is very experimental: it works fine with 1 or 2 vectors (move, > rotate, scale operations), it becomes imprecise if a 3 vector introduces a > high shear operation > Best regards > Peppe > > > ------------------------------------------------------------------------------ > > _______________________________________________ > Jump-pilot-devel mailing list > Jump-pilot-devel@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/jump-pilot-devel > >
