What are you doing in '//SOME ACTIONS'?

Nothing. Source code run as is.
I found one the solve:


MagickImage img = new MagickImage(@"d:\TEST\brightness\tiles\32-1-470-109-25.tif");
byte[] color = new byte[3];

for (int y = 0; y < img.Height; y++)
{
PixelCollection pc = img.GetReadOnlyPixels ...

Does that help?

No, I modified my code:

MagickImage img = new MagickImage(@"d:\TEST\brightness\tiles\32-1-470-109-25.tif");

for (int y = 0; y < img.Height; y++)
{
PixelCollection pc = img.GetReadOnlyPixels(0, y, img.Width, 1);

for (int x = 0; x < pc.Width; x++)
{
byte[] color = pc ...

If the first loop by x, the second loop by y, I received next result:
start load -> 14:51:34
start loop -> 14:51:46
end loop -> 14:58:53

If the first loop by y, the second loop by x, I received next result:
start load -> 15:05:56
start loop -> 15:06:08
end loop -> 15:12:56

I need to precess each pixel on image:

MagickImage img = new MagickImage(@"d:\TEST\110706M01000509.jpg");
PixelCollection pc = img.GetReadOnlyPixels(0, 0, img.Width, img.Height);

for (int x = 0; x < pc.Width; x++)
for(int y = 0; y < pc.Height; y++)
{
byte[] color = pc.GetValue(x,y);

Please, help me. How to change pixel color on the image. I use the following code:

MagickImage img = new MagickImage(@"d:\TEST\110706M01000509.jpg");
WritablePixelCollection pc = img.GetWritablePixels(100, 100, 50, 50);

foreach (Pixel p in pc)
{
p.SetChannel(0, 255);
p.SetChannel(1, 0);
p ...
