示例1: TestClearBitmap
public void TestClearBitmap()
{

// Loop through the image checking the pixels now
for (int y = 0; y < bitmap.Height; y++)
{
for (int x = 0; x < bitmap.Width; x++)
{
if (bitmap.GetPixel(x, y).ToArgb() != Color.Red.ToArgb())
{
Assert.Fail(
"Immediately after a call to FastBitmap.Clear(), all of the bitmap's pixels must be of the provided color");
}
}
}
// Test an arbitratry color now
