TImagingBitmap comes with the property "Canvas" (TCanvas).
Like every other Canvas, this provides methods such as TextOut, TextRect and so on.

If you use TCanvas for text output and want transparent text, you must set background mode to transparent. Using WinAPI function would look like this SetBkMode(Canvas.Handle, TRANSPARENT). There's probably some method/property in TCanvas that would do the same.
