Instead of using scanLine() to get single rows, you could use bits() to get a
pointer to the entire image. It is equivalent to scanLine(0), but bits() is
more self-explanatory when accessing the whole image. The result is an array of
width() * height() tuples, each of type QRgb (after the correct cast has been
applied). To get a border around the entire image, try:
QRgb* bits = reinterpret_cast<QRgb*>(photoImg.bits());
QRgb black = qRgba(0, 0, 0, 255);
int width = photoImg.width();
int height = photoImg.height();
// Top border
for (int i = 0; i < width; ++i)
bits[i] = black;
// Bottom border
for (int i = width * (height - 1); i < width * height; ++i)
bits[i] = black;
// Left border
for (int i = 0; i < width * height; i += width)
bits[i] = black;
// Right border
for (int i = width - 1; i < width * height; i += width)
bits[i] = black;
This is all off the top of my head and I have not tried compiling it - so it
might need some massaging to get it past the sturdy compiler ;).
