Hello

I want to implement zoom on an btb image . I have my array with pixels , my goal is to take the first pixel , store it in another array in a block of 4 by 4 pixels and then I need to do this with the rest of the array.

So what I want to do is this:

C#

pixelArray[1,1] =     {{2,3}       
                       {4,5}}

this:

C#

{{2,2,3,3}
 {2,2,3,3}
 {4,4,5,5}
 {4,4,5,5} }

Is there a function in C# ?
How should I solve this problem??
Thank you!

There is no function in .NET to do that AFAIK.
It wouldn't be difficult to write, but it seems a strange way to do it: why are you "zooming" an image by doublingthe size? Why not do the zoom in the paint routine, where you would only enlarge the actual bit they are viewing? You can do that by constructing a Matrix object and apply a scale factor before using it to transform the graphics object. Easy, quick and simple:
Add the Matrix to your class:

C#

using System.Drawing.Drawing2D;

Construct a new matrix:

C#

Matrix m = new Matrix();

Scale the X by 1/2 and the y by 1 1/2:

C#

m.Scale(0.5F, 1.5F);

Apply the transformation:

C#

e.Graphics.Transform = m;

Yes, you can use one or more of the static methods System.Array.Copy, http://msdn.microsoft.com/en-us/library/system.array.aspx[^].

If by any reason you find those methods too hard to understand (yes, at least they need considerable attention), you are reduced to copying one element at a time in a loop. I hope this is clear enough.
