Hi Peppe, thanks for you work!
By now I am not having any suggestions yet. However, a question I have is: Do we not have any TIF export in OJ that avoids use of jai? We really need to try to avoid JAI, because the OSGeo LiveDVD works only with OpenJDK (as far as I know). Can you push the code to a plugin folder or the core? to have a look at it. Maybe we should also think about a simple checkbox on the dialog that offers to save the "raw DEM data", and not the image data. Or better: make to separate functions, using the same code plugin code, but having just a boolean value set use the original DEM values? cheers, stefan Am 13.07.13 12:42, schrieb Giuseppe Aruta: > I forgot: the plugin is available on Toolbar Raster menu > > > 2013/7/13 Giuseppe Aruta <giuseppe_ar...@yahoo.it > <mailto:giuseppe_ar...@yahoo.it>> > > Hi Stefan (and others), > I worked on your code and expanded a little bit the plugin. > I came across this plugin which is an attempt to larger Save to > Raster to substitute SaveRasterImageToImagePlugin from Pirol on > Sextante Layers. > I used some codes from Kosmo and OJ, removing any external jar > depency and only using JAI and ImageIO options.
