Crop Texture2D in XNA
I needed to crop an image in XNA, but I didn't find a solution (Ok i really didn't search much :) ) and so I had to do it by myself. Here is the code in case you need it too. (XNA 4.0)
public static Texture2D Crop(Texture2D source, Rectangle area)
{
if (source == null)
return null;
Texture2D cropped = new Texture2D(source.GraphicsDevice, area.Width, area.Height);
Color[] data = new Color[source.Width * source.Height];
Color[] cropData = new Color[cropped.Width * cropped.Height];
source.GetData(data);
int index = 0;
for (int y = area.Y; y < area.Y + area.Height; y++)
{
for (int x = area.X; x < area.X + area.Width; x++)
{
cropData[index] = data[x + (y * source.Width)];
index++;
}
}
cropped.SetData(cropData);
return cropped;
}
