I am trying to achieve a result similar to the photo below. I want to display the file information, address, and logo in the top right corner of the image. I have developed an application that allows users to take a photo and add the file name, address, and a logo to it, but the result is not what I expected. The text takes up too much space on the captured photo.
If you have a solution to achieve a result similar to the desired photo, I would greatly appreciate it.
Thanks,
Nicolas
Output from my application
Expected result
I’m using opencv library on Android Studio to archieve the request I tried this code to
public static Bitmap addTextToImage(Bitmap bitmap, String filename, String address) {
Mat mat = new Mat();
Utils.bitmapToMat(bitmap, mat);
Scalar textColor = new Scalar(120,156,181);
int fontFace = Imgproc.FONT_HERSHEY_SIMPLEX;
double fontScale = 0.21;
int thickness = 1;
int padding = 5;
String text = filename + " Adresse: " + address;
Size textSize = Imgproc.getTextSize(text, fontFace, fontScale, thickness, new int[1]);
// Position du texte : en bas à droite
Point textPosition = new Point(
mat.cols() - textSize.width - padding,
mat.rows() - padding
);
// Dessiner un rectangle semi-transparent derrière le texte
Rect textBackground = new Rect(
(int) (textPosition.x - padding),
(int) (textPosition.y - textSize.height - padding),
(int) (textSize.width + padding * 2),
(int) (textSize.height + padding)
);
Scalar backgroundColor = new Scalar(255, 255, 255, 150);
Imgproc.rectangle(mat, textBackground.tl(), textBackground.br(), backgroundColor, Imgproc.FILLED);
Imgproc.putText(mat, text, textPosition, fontFace, fontScale, textColor, thickness);
// Convertir à nouveau Mat en Bitmap
Bitmap resultBitmap = Bitmap.createBitmap(mat.cols(), mat.rows(), Bitmap.Config.ARGB_8888);
Utils.matToBitmap(mat, resultBitmap);
return resultBitmap;
}
Picture code taken:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == Camera.REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
Location lastLoc = loc.getLastLoc();
if(lastLoc == null)
{
return;
}
String filename = generateFileName();
Bundle extras = data.getExtras();
Bitmap imageBitmap = (Bitmap) extras.get("data");
Bitmap finalBitmap = PhotoAnnotator.addTextToImage(imageBitmap, filename, mSelectedAddress);
saveImageToGallery(filename, finalBitmap, lastLoc);
}
}
