Masked Transform with 32bppArgb

I am using Aurigma graphicmills with C# ,

Aurigma.GraphicsMill.Transforms.Combiner combiner = new

Aurigma.GraphicsMill.Transforms.Combiner();

combiner.CombineMode = Aurigma.GraphicsMill.Transforms.CombineMode.Copy;

//Combine with the first image.

combiner.SourceBitmap = photo1;

combiner.SourceRectangle = new RectangleF(0, 0, photo1.Width, photo1.Height);

combiner.DestinationRectangle = _RectRubberband.Rectangle;

combiner.ApplyMaskTransform(background, mask);

using above code to create mask transform.. when using 24bppArgb image as background image its working fine , if using 32bppArgb Images it will make error ( message :Pixel format of mask bitmap has an unappropriate value.) .How can i solve it? please help me soon...
