Binary inside android/dist/ folder

Functions:

tint

tint.tint({
  image : img1.toBlob(), imageOverlay : img2.toBlob(), color : "#ff0000", modeColor : "overlay", modeImage : "overlay"
});

mask (mask needs to be a transparent png)

tint.mask({
  image : img1.toBlob(), mask: img2.toBlob()
});

Example:

xml:

<Alloy>
	<Window>
		<ImageView id="img1"></ImageView>
		<ImageView id="img2"></ImageView>
		<ImageView id="img_final"></ImageView>
	</Window>
</Alloy>

var tint = require("miga.tintimage");

/*
// two images and color
$.img_final.image = tint.tint({
image : $.img1.toBlob(), imageOverlay : $.img2.toBlob(), color : "#ff0000", modeColor : "overlay", modeImage : "overlay"
});
*/

/*
//mask
tint.mask({
  image : img1.toBlob(), mask: img2.toBlob()
});
*/

// color overlay
$.img_final.image = tint.tint({
    image : $.img1.toBlob(), color : "#ff0000", modeColor : "multiply"
});

$.index.open();
