I am trying to scan a local image through ZBar, but as ZBar don't give any documentation for Android but only give detailed documentation for iPhone I had customized camera test activity too much. But I didn't get any success.
In ZBar cameratest activity
PreviewCallback previewCb = new PreviewCallback() {
public void onPreviewFrame(byte[] data, Camera camera) {
Camera.Parameters parameters = camera.getParameters();
Size size = parameters.getPreviewSize();
Image barcode = new Image(size.width, size.height, "Y800");
barcode.setData(data);
int result = scanner.scanImage(barcode);
if (result != 0) {
previewing = false;
mCamera.setPreviewCallback(null);
mCamera.stopPreview();
SymbolSet syms = scanner.getResults();
for (Symbol sym : syms) {
scanText.setText("barcode result " + sym.getData());
barcodeScanned = true;
}
}
}
};
I want to customize this code so that it uses a local image from the gallery and gives me the result. How do I customize this code for giving a local image from the gallery and scan that image?
