Hi,

I have an app with an roScreen, and I can do a DrawRect, DrawObject, and DrawScaledObject successfully, however when I try DrawText, I get no output from that call.

    screen = CreateObject("roScreen", true, 1280, 720)
    fontReg = CreateObject("roFontRegistry")
    font = fontReg.GetDefaultFont()
    screen.DrawText("Hello", 100, 100, &hFF00FF00, font)
    screen.SwapBuffers()

also tried drawing text into a region (like the simple2D example) but still no output.

    drawingRegion = dfSetupDisplayRegions(screen, 100, 100, 400, 60)
    s = drawingRegion.main
    s.DrawText("Hello", 100, 100, &hFF00FF00, font)

It's odd that the font and fontReg variables don't seem to contain anything when printing with printAA. However I get the same output from the simple2d sample code -- which does display text correctly.

---- AA ----
Nothing from for each. Looks like : ?roFontRegistry?
------------
---- AA ----

Any suggestions for getting DrawText to work?

Colors are specified in RGBA order. So your color &hFF00FF00 is completely transparent. Try using FF in the low order byte.

--Mark

It's worth pointing out that this is the opposite of colors used on an roImageCanvas, which is ARGB.

Thanks! I was porting my layout code from roImageCanvas (which was too slow for my application). changing the color format fixed it.
