Implementations

impl AndroidBitmap

pub unsafe fn from_jni(env: *mut JNIEnv, bitmap: jobject) -> Self

Safety

This function should be called with a healthy JVM pointer and with a non-null android.graphics.Bitmap, which must be kept alive on the Java/Kotlin side.

pub fn get_info(&self) -> BitmapResult<AndroidBitmapInfo>

pub fn lock_pixels(&self) -> BitmapResult<*mut c_void>

pub fn unlock_pixels(&self) -> BitmapResult<()>

pub fn get_hardware_buffer(&self) -> BitmapResult<HardwareBufferRef>

Available on crate feature api-level-30 only.

Retrieve the native object associated with a HARDWARE AndroidBitmap.

Client must not modify it while an AndroidBitmap is wrapping it.
