How can I export Text Layer as PNG?

I'm extending the Outbound sample to have each layer exported as a PNG file. I got it done for RGB layers, but it does not work for Text Layers.

For text layers I got the rectangle where the text should be drawn, but no text. That's fine. The pExportRecord->pReadLayerDesc->name brings the Text value, but I could not find where to find information about font size, font style, font name, font color, and so on.

Could someone help me on that?

Thanks
