Hi MIchael, I apologize for my late answer. > There are a little bit hidden (not documented), especially the one for sextante as you have to use a plugin to create the Warping Vectors (unless you know you just have to create a layer with this name) and another tool to apply the transformation.
Yes. This tool (warping from vectors) is become deprecated as last year I reworked Warp toolbox in order to add "Affine transformation" (which is exactly what warping from vector does - but only for vector Layer not RasterImageLayer neither ReferenceImageLayer). Maybe I need to extend a bit original Jump documentation. > The only problem I found is with the resolution. If the transform increases the image size, the resolution of the resulting image decreases (see image attached). You added a checkbox to get a lower definition, but I did not find an option to keep a resolution similar to the input one. I used the javax.media.jai.Warp class fro transformation. This class can do translate/rotation/share of an image on the same time but possibly ithas some limits (even using different interpolation method). I should have to study the case. Originally my need was only to use on scanned maps where the topographic base map was already projected (and the scan more accurate as possible), so the warp should have only correct minimal rotation, scale (if any) and save the translation to original coordinates (creating a world file). The lower definition was only to rescale the resolution to half if the "reprojecting process" was requiring a huge ammount of memory. I will give a look in the next month. As I wrote these were experimental tools Best regards Peppe Il giorno lun 11 feb 2019 alle ore 22:34 Michaël Michaud < m.michael.mich...@orange.fr> ha scritto: > > Hi Peppe, > > Just a quick feedback. Firstly, the tools you added work fine. Thanks a lot for that. There are a little bit hidden (not documented), especially the one for sextante as you have to use a plugin to create the Warping Vectors (unless you know you just have to create a layer with this name) and another tool to apply the transformation. The only problem I found is with the resolution. If the transform increases the image size, the resolution of the resulting image decreases (see image attached).

Michaël Le 06/02/2019 à 12:45, Giuseppe Aruta a écrit : Hi MIchael, Nicolas During the last years I added two experimantal tools for images on OpenJUMP, available on the standard Affine transformation one: 1) if the image is loaded via Sextante Raster Image (File>Open>Sextante..) Tools>Warp>Affine transformation (from warping vectors). Note that this requires at maximun 3 warping vectors on the view (Tools<Warp>Warpimg to get the tool to draw warping vectors) 2) if the image is loaded via Referenced Image or similar (File>Open>File) Tools>Warp>Affine Transformation (from parameters) At the end of the dialog there is a check box "Force affine transformation of image". If it is checked the affine transformation acts also on the bufferedimage (and not only on the geometry). The option "Resize image to half size" should help if the process takes too much time (and too much CPU) I wrote a small tutorial here: http://ojwiki.soldin.de/index.php?title=Warp#Applying_an_affine_transformation_to_an_image_layer Both methods work made only affine trasformation. And they create new GeoTIFF image files rather then "write/rewrite" a world file. Rewriting a world file rather then rewrite the all image should be preferible and "less memory consuming". Unfortunatelly OpenJUMP still cannot read and use the rotation/skewing lines on a worldfile. Both methods should work if the image is not huge. There is no way to control possible errors Peppe Il giorno mer 6 feb 2019 alle ore 09:23 Nicolas Ribot < nicolas.ri...@gmail.com> ha scritto: > Hello, > > QGIS can do that with Raster georeferencing.
