... Templot as design quality (fast -- simple pixel shrink/stretch), and display quality (slow -- Lanczos3 resampling). More about using these options at: topic 1928 I tried adding your image (original size from the Image Gallery) to the sketchboard. I set the image width for 4mm scale to 12500mm, which was a quick guess. It's somewhere near, as this overlaid B6 crossover shows for the track centres. These are the views back on the trackpad for each quality option: design quality: 2_271730_110000001.png display quality: 2_271730_110000000.png As you can see, neither is going to be much use for detailed track planning, although you can get the general alignments. No algorithm can put back detail which has been removed. The latter is marginally better, but very much slower to zoom and pan when working over it. These images are sketchboard bitmap items, not background picture shapes. The background picture shapes function uses a simple pixel stretch only. regards, Martin. posted: 28 May 2012 02:42 from: Pierre quote ...
