decodeRegion()

abstract android.graphics.Bitmap com.navigine.idl.java.BitmapRegionDecoder.decodeRegion ( Rectangle rect, float sampleSize )

abstract

Method is used to decode rectangle region in the image specified by rect.

Parameters

rect	area to render Rectangle
sampleSize	if set to a value > 1, requests the decoder to subsample the original image, returning a smaller image to save memory.

Returns

constructed bitmap

Java code snippet:

        // Decode region with sample size 1 (full resolution)
        ImageWrapper decodedImage = decoder.decodeRegion(sampleRect, 1);
        System.out.println("Decoded region: " + sampleRect.getWidth() + "x" + sampleRect.getHeight() + " at sample size 1");

Kotlin code snippet:

        // Decode region with sample size 1 (full resolution)
        val decodedImage = decoder.decodeRegion(sampleRect, 1)
        println("Decoded region: ${sampleRect.width}x${sampleRect.height} at sample size 1")

newInstance()

static BitmapRegionDecoder com.navigine.idl.java.BitmapRegionDecoder.newInstance ( byte[] data )

inlinestatic

Method is used to create instance of BitmapRegionDecoder.

Parameters

data	raw image data (could be raw svg string)

Returns

nstance of decoder, which could be used for decoding byte array to bitmap.

Java code snippet:

        // Create new instance of BitmapRegionDecoder
        decoder = BitmapRegionDecoder.newInstance(imageData);
        System.out.println("Created BitmapRegionDecoder instance");

Kotlin code snippet:

        // Create new instance of BitmapRegionDecoder
        decoder = BitmapRegionDecoder.newInstance(imageData!!)
        println("Created BitmapRegionDecoder instance")
