PaintOnGraphics does not preserve Graphics.Transform

In an application we show barcodes on screen and print them on labels.
When printing, we normally do this by rotating the Graphics 180 degrees about the centre.
Since PaintOnGraphics apparently creates a new transform, rather than using the current transform, barcode elements are printed rotated 180 degrees about the centre. Any items printed after the barcode are also rotated about the page - this is a serious problem

Try the following:

Matrix matrix = g.Transform;

// do the font painting

g.Transform = matrix;

matrix.dispose;

Basically capture what the tranform settings are before the font is painted and then reset the transform. It looks like the paint operation is doing a transform on the Graphics object and is not resetting it when it's done.

Hope that helps,

Gary
