1 | # ScratchCardCompose
2 | A customizable scratch card component built with Jetpack Compose, based on masking techniques, which allows users to "scratch" an overlay image to reveal a base image underneath. For a real-world usage example, see this component in the full project [here](https://github.com/AdamDawi/Popcorn-Picks).
3 |
4 | ## ⭐️Features
5 | ### Main Screen
6 | - **Scratch Overlay Masking:** The overlay image uses masking with transparency and blend modes to simulate scratching effects.
7 | - The ``BlendMode.Clear`` ensures the scratched pixels are completely erased.
8 | - ``CompositingStrategy.Offscreen`` ensures that the base image remains unaffected by masking.
9 |
10 | - **Threshold Control:** Define the percentage of the overlay that needs to be scratched to reveal the base image.
11 |
12 | - **State Management:** The component tracks whether the card has been fully scratched and triggers a callback when it's complete.
13 |
14 | ## 🎥Here are some overview videos:
15 | 
16 | 
17 |
18 | ## ⚙️Installation
19 | To use this component in your Jetpack Compose project, simply copy the ``ScratchCard`` composable into your project and customize it with your own images and configurations.
20 |
21 | ## 📝Usage Example
22 | Here’s an example of how to use the ScratchCard component:
23 | ```kotlin
24 | ScratchCard(
25 | modifier = Modifier
26 | .height(200.dp)
27 | .width(300.dp),
28 | overlayImage = ImageBitmap.imageResource(R.drawable.overlay_image),
29 | baseImage = painterResource(R.drawable.base_image),
30 | onScratchComplete = {
31 | // Handle when the card is completely scratched
32 | },
33 | isScratched = false,
34 | shape = RoundedCornerShape(12.dp),
35 | scratchLineWidth = 32.dp,
36 | scratchingThresholdPercentage = 0.7f
37 | )
38 | ```
39 |
40 | ## 🔍How it works
41 | The scratch card uses a layered rendering approach:
42 | 1. Base Image: Displayed at the bottom of the stack.
43 | 2. Overlay Image: Rendered above the base image and acts as a mask.
44 | 3. Scratch Lines: Drawn using Canvas and rendered with BlendMode.Clear to erase parts of the overlay image.
45 |
46 | ## 🎨Customize Options
47 |
48 | | Parameter | Description | Default |
49 | |-------------------------------|---------------------------------------------------------------------------------------------------------------|-----------------------|
50 | | `modifier` | Modifier to be applied to the ScratchCard. | `Modifier` |
51 | | `overlayImage` | The image that will be scratched off by the user, typically a texture or effect to reveal the base image. | _None_ |
52 | | `baseImage` | The base image that will be revealed after the overlay is scratched off. | _None_ |
53 | | `scratchingThresholdPercentage` | The percentage of the area that needs to be scratched off to show the base image. | `0.8` |
54 | | `scratchLineWidth` | The width of the scratch lines drawn when the user drags their finger across the overlay. | `32.dp` |
55 | | `scratchLineCap` | The shape of the stroke cap applied to the scratch lines. | `StrokeCap.Round` |
56 | | `isScratched` | Flag to determine if the scratch card is fully scratched. If true, no further scratching is possible. | `false` |
57 | | `onScratchComplete` | Callback triggered when the scratch card is fully scratched, meaning the threshold has been reached. | `{}` (empty lambda) |
58 | | `shape` | The shape of the scratch card, typically a rounded rectangle or custom shape. | `RoundedCornerShape(12.dp)` |
59 |
