Hi, It feels a bit odd that it is not possible to re-use existing image layers stored into JML format in other projects simply by opening the catalog file from user interface. I am doing similar things pretty often with Quantum GIS and GDAL vrt files which I create with gdalbuildvrt http://www.gdal.org/gdalbuildvrt.html
Image layer manager is a sketch. For OpenJUMP user interface it is a normal vector layer and it is possible to insert new features by digitizing, copying from other layers and as WKT. All those operations are useless unless user copies features from other image layers. Fortunately nonsense features in image layer seem to lead only to Class Not Found Exception messages in the lower left corner. Possibility to hand edit attributes may be useful sometimes for changing image paths but not for anything else. And if a normal user opens a tiff file and gets layer named "image.tif" I guess that he believes that menu option "Save dataset as" means saving image to some other image format and not saving image footprint into vector file. I think that before advertising image layer tool too much we should think what would be a good way to use this nice feature and how user interface should support the usage. My opinion is that the first thing to do would be to separate the image catalogue layers somehow from the normal vector layers and make them editable only through Image Layer Manager which should have more features than it has now. -Jukka- edgar soldin wrote: > move it over to jump-devel. > > true, the OJ image loader works that way. > > a am not sure about your catalog idea though as i feel, creating a image > collection layer once and saving it with the project should be sufficient for > most use cases. > > i think: > A. we should place the image layer manager more prominently for users to > discover this mechanism (higher in layer context menu, add to layer menu). > B. replace the image layer icon with a multiple images icon > > ..ede > > > On 15.03.2013 10:14, Jukka Rahkonen wrote: > > Hi, > > > > Add image layer is much more than another name for "Open image file" > > but nobody knows it and the image layer system has never been > > programmed ready.
