}Snapshot builds
Snapshot versions are available at Sonatype OSSRH's snapshot repository. These are updated on every commit to main.
To use it:
repositories {
maven("https://s01.oss.sonatype.org/content/repositories/snapshots") // build.gradle.kts
maven { url 'https://s01.oss.sonatype.org/content/repositories/snapshots' } // build.gradle
}
dependencies {
implementation("com.mxalbert.zoomable:zoomable:<version>-SNAPSHOT")
}Zoomable {
val painter = painterResource(R.drawable.image)
val size = painter.intrinsicSize
Image(
painter = painter,
contentDescription = null,
modifier = Modifier
.aspectRatio(size.width / size.height)
.fillMaxSize()
)
}Note that Modifier.aspectRatio() is needed in order to remove the extra space around the image
when the image is zoomed.
For how to use Zoomable with Coil, see
the sample.
Improvements and behavior changes compared to the original version:
- This version is mainly intended to be used to show images. If the image is larger than the screen, when zoomed, the original version will show the upscaled version of the downscaled image, while this version will directly scale the image to the zoomed size, which has higher quality.
- Contents will follow finger position when zooming with two fingers.
- Supports animating scale level and translation at the same time.
- Other features
