In landscape orientation, I using
myImageView.setImageBitmap(myBitmap) and using an
ontouch listener to
getY and adjust for location of
myImageView (same as
getRawY). I then use
bitmapToMat to build a MAT to process the image more with OpenCV. I found two resizing scenarios where the
onTouch location will draw a circle exactly where I touched but at times the location will be outside the Mat and cause a NPE and fail during processing.
resize(myImageView.getHeight(), myImageView.getWidth()) and
x = x(myImage.getHeight()/myImageView.getWidth())
y = y(myImage.getWidth()/myImageView.getHeight())
If I dont change the x,y I can click everywhere in image w/o the NPE but the circle drawn is nowhere near where I touched.
After processing I
matToBitmap(myMAT, newBitmap) and
I am obviously missing something but is there there a simple way to get the touch location and use that location in a MAT? Any help would be awesome!
