A bash script for automatically scrolling and stitching screenshots of Android apps. Detects and accounts for overlapping pixels.
- bash or a similar shell
- imagemagick
$ scrollshot.sh <filename> <iterations> <footer keep> <footer ignore> <distance> <start> <overlap> <end>| argument | default | purpose |
|---|---|---|
filename |
scrollshot | name of the output file, without .png |
iterations |
3 | number of iterations to scroll |
footer keep |
auto | bottom area to keep in output and ignore when scrolling (in pixels) |
footer ignore |
0 | additional bottom area to ignore when scrolling (in pixels) |
distance |
2 * dpi | distance to scroll per iteration (in pixels) |
start |
-4dp | initial overlap test offset (in pixels) |
overlap |
20dp | height of overlap test area (in pixels) |
end |
4dp | final overlap test offset (in pixels) |
- Keep the floating action button from repeating with
footer ignoreset to about78dp. - To preserve spacing in apps with a lot of whitespace (identical vertical pixels), increase
overlap. - Blinking cursors will fool the automatic footer detection.
