This means you very much better call Dispose() on those objects are you are done with them (way many paths here with UI event handlers), or put them into using blocks. Note that Bitmap inherits from Image, which implements IDisposable. If (bmp1.GetPixel(x, y) != bmp2.GetPixel(x, y)) Test to see if we have the same size of image Private bool compare(Bitmap bmp1, Bitmap bmp2)īool flag = true //Inner loop isn't broken Private void button3_Click(object sender, EventArgs e) //compare button Image2 = new Bitmap(openDialog.FileName) Private void button2_Click(object sender, EventArgs e) //second image open Image1 = new Bitmap(openDialog.FileName) If (openDialog.ShowDialog() = DialogResult.OK) OpenFileDialog openDialog = new OpenFileDialog()
Private void button1_Click(object sender, EventArgs e) //first image open Is there a more efficient and faster way to compare 2 if 2 images are the same? Bitmap image1 = null I heard that GetPixel() method may be slow. It basically uses the open dialog and opens 1 image at a time and puts it in 1 picture box. This is my program code for comparing if 2 images are the same.
