Hello friends,
-
Fill an area of an image with a color.
-
The image file must be in the SdCard (root or folder). Example: file:///mnt/sdcard/kitty.png
-
A Canvas.TouchDown is necessary.
-
Each time the color changes the file:///mnt/sdcard/kitty.png is modified.
-
Using the “ CopyAssetFile ” block, you can copy a file from the asset to the SdCard.
(base destination is: /mnt/sdcard/) -
If you want to resize the image, use the “imageWidth” and “imageHeight” blocks.
