Hi larry, I tested the HiRes of SkyJUMP. Here is the results First of all: SkyJUMP imports only JPG so I transformed a ECW file in JPG (SkyJUMP doesn't use SIGLE plugin for ECW) I used a JPG file with standard PIXEL 5815/3895 dim. but with 400 DPI,the double DPI as required by Italian Topographic maps.
1) To export to HiRes, SkyJUMP requires at least an extra vector file with at least one feature, otherwise it doesn't export the pure raster layer 2) I exported the map at 2000 Resolution 3) Skyjump was quite fast, around 30 sec. on my Athlon 1800 (a wee bit old :-)) 4) the output image was OK (2000x1689 PIXEL. DPI is 72 5) enlarging the image to original 5815 width dim. it works fine (except that the DPI is 72-derived) I think that it is OK. Export to HiRes Image could be a good tool for OpenJUMP, better than the actual Export to image. Instead to have 2 export image tools, I tghink that Export to HiRes should substitute the Export image, saving the possibility to write a world file.
