Selecting camera input

camera input selection isn't directly available via the api yet, however, in order to dynamically isolate your camera input into a bitmap, you can use the following function where previewwidth and previewheight depend on your current resolution, this means you must keep track of resolution changes //cameraresolution sd val previewwidth = 1280 val previewheight = 480 //cameraresolution md // val previewwidth = 2560 // val previewheight = 720 //cameraresolution hd // val previewwidth = 3840 // val previewheight = 1080 fun bytearraytocroppedbitmap(bytearray bytearray?) bitmap? { val yuvimage = yuvimage(bytearray, imageformat nv21, previewwidth, previewheight, null) val os = bytearrayoutputstream() yuvimage compresstojpeg(rect(0, 0, previewwidth, previewheight), 100, os) val jpegbytearray = os tobytearray() val bmp = bitmapfactory decodebytearray(jpegbytearray, 0, jpegbytearray size) return bitmap createbitmap(bmp, 0, 0, previewwidth / 2, previewheight) }
