如何增加zxing的扫描面积？

Question

I want to increase the scanning area size of ZXing , I have already added the ZXing libraries to my app, but I find the scanning area is too small. I want to scan a large barcode, and I have encountered an error:

Crop rectangle does not fit within image data.

The getFramingRectInPreview() method and getFramingRect() method does not return the same size Rect .

Answer 1

Try this one

private static final int MIN_FRAME_WIDTH = 240;  // (your desired value here)
private static final int MIN_FRAME_HEIGHT = 240; // (your desired value here)

Answer 2

To CameraPreView.java calculateFrames method and resize framingRect

framingRect.set(left,top,right,bottom);

I use this project to implement zxing scan :
