0003730: SAS，Need to perfect the direction

Notes
(0020028) zed (manager) 22-12-2020 15:48	Your screenshot is OK - JPEG doesn't support transparency (alpha channel). Describe in detail what you expect from SAS?

(0020029) mrjack (reporter) 23-12-2020 07:59	Not in JPG format, the original image is in tif format. gloabmaper has a function. According to the primitive boundary. Such as kml. It is a triangular shape. You can crop a rectangular image into a triangle. Image downloaded by SAS. Level polygon frame selection. The downloaded images, stitched together, are not polygons, but opposite sex. All around are the tile shapes of gears. Looks worse

(0020030) mrjack (reporter) 23-12-2020 08:05	Just like the picture above, the frame itself is selected as a triangle, and it is weird to splice it out by contact. If you download according to city boundaries. That's worse. Only call up other software for cutting. kind of hard. Secondly, there is another suggestion. Why download the image? First download the image tile, then download the overlay. Then stitch together, and finally cut it on other software. Very troublesome, like going back to the bedroom and needing a key. After opening it, I found that there were 3 doors behind. GOD. In fact, why can't you choose to download the tiles and overlays together when you download the tiles. Then automatically stitch and export pictures. In other words, SAS script can do it?

(0020031) mrjack (reporter) 23-12-2020 08:11	Sorry, SAS is a free software that is already very good. Just a small suggestion. Thank you

(0020032) zed (manager) 23-12-2020 08:21	I attached 2 screenshots: first from SAS, second from GlobalMapper. This is how SAS works - it can stitch tiles, but you will get transparent holes if some tiles missed (if imagery format support transparency). So, to avoid this holes you must download all tiles with rectangle selection. > In other words, SAS script can do it? No. And this will not changed in the future.
