将纹理数组加载到单个图像组件中，并放入Unity 4.6中的网格布局中（使用uGUI）

Question

I'm having a lot of trouble trying to develop a loader that grabs a group of textures located in an array and populates them into a grid layout. Could anyone share some code insight or a snippet that might do the trick?

Lets say you want to show your images in the format below. What you can do is merging your images into a 1 big Texture2D (But as I know image size should not exceed 2048x2048)

The function below should do the work:

private Texture2D ConcatTexture(Texture2D[,] textures, int imageWidth, int imageHeight)
{
    int rowCount = textures.GetLength(0);
    int columnCount = textures.GetLength(1);

    //Space allocation for the final texture
    Texture2D finalTexture = new Texture2D(columnCount * imageWidth, rowCount * imageHeight);

    for (int i = 0; i < rowCount; i++)
        for(int j=0 ; j < columnCount ; j++)
            finalTexture.SetPixels(j * imageWidth, (rowCount-i-1) * imageHeight, imageWidth, imageHeight, textures[i, j].GetPixels());

    return finalTexture;
}

You can also edit this code and put some spaces between images if it is what you are looking for.
