-
-Select the base image you want to use.
-
-Image type: APNG
-Transparent background: Yes
-Foreground color: F2A555 (or select a color)
-Animation speed: (default value)
-Preloader size: 16 x 16
-
-(no Advanced Options changed)
-
-Additional download options:
-
-Check Download as sprites
-
-Press Download now
-
-Rename the file to base.png
-
-convert -dispose 3 -delay 10 base.png -crop 16x16 +repage update_spinner.mng
-
-If you want to use the make_spinner.py (gives worse results):
-
-In http://preloaders.net/en/circular change
-
-Preloader size: 128 x 128
-
-Press Download now
-
-Rename the file to base.png
-
-convert base.png -crop 128x128+0+0 reload_scaled.png
-
-and use the make_spinner.py . Note that the results aren't very good.
