Question

I have an image that has portions of it that are fully transparent and then some portions that are at like 50 alpha Is there any way to make the 50 alpha portion of the Image fully opaque but still keep the portion of the image that s fully transparent The only thing I can think of is if there is some sort of blend mode I can do to blend my image with a fully black background or something but I kind of don t know where to start

```Image colorFilter = ColorFilter ColorMatrix floatArrayOf 1f 0f 0f 0f 0f 0f 1f 0f 0f 0f 0f 0f 1f 0f 0f 0f 0f 0f 2f 0f ```

Ended up getting this to compile but it didn t work The Image didn t change at all I ll try to look up the color filter + color matrix docs and play around with those values a bit ```colorFilter = ColorFilter colorMatrix ColorMatrix floatArrayOf 1f 0f 0f 0f 0f 0f 1f 0f 0f 0f 0f 0f 1f 0f 0f 0f 0f 0f 2f 0f ```

black opaque is different than just opaque

Oh If I can just make it opauqe then that s fine too I thought I HAD to mix it with another color

the matrix I wrote should translate 50 to 100 in the alpha component but maybe it doesn t work with the painter that image sets up not sure

Colton Idle · Answer

is that matrix only targetting 50 alpha pixels if so then maybe thats the issue Maybe my example I gave was misleading in the way that I m trying to take any pixel that aren t fully opaque or fully transparent and make those fully opaque

well 255f instead of 2f would cause any level of non transparent to become opaque but I wonder if the blending is using the original alpha

Colton Idle · Answer

Hm yeah i increased it to 255 and still get the same result

wait maybe im an idiot maybe border in compose draw above all children elements

Colton Idle · Answer

Now I just gotta figure out how to draw over a border hm ```Box modifier = modifier fillMaxWidth height IntrinsicSize Min border 4 dp Color Magenta RoundedCornerShape 20 dp background Color Green RoundedCornerShape 20 dp AsyncImage model = ImageRequest Builder LocalContext current data <https i imgur com VZrnePC png> crossfade true build contentDescription = null contentScale = ContentScale FillHeight modifier = Modifier height 100 dp fillMaxWidth align TopCenter offset y = 44 dp ```
