I have created a sample how to create 3D-preview of business card using Graphics Mill. You can find a sample rendering bellow. Code: private void button1_Click(object sender, EventArgs e)
{
CreateBusinessCardPreview(@"C:\template.psd", @"C:\result.png";
}
private void CreateBusinessCardPreview(string sourcePath, string destPath)
{
//Inititally we draw on image of large size for better quality
