Using a custom TextStyle

[benoitmasson]

Hi, I can't find a way to customize the TextStyle in my calls to gc.FillString().

This type (and all its field, in particular Halign which I'm interested in) do not seem to be used in any of the packages.

Am I missing something, or is there another way to have gc.FillString() draw centered text?

Hi @benoitmasson, it's not implemented yet.

OK, thanks for the quick response.

Meanwhile I wrote a small workaround for my specific needs, in anybody has the same issue:

func fillStringHCenteredAt(gc draw2d.GraphicContext, text string, x, y float64) float64 {
	// draw text outside of image, to compute width without printing
	w := gc.FillStringAt(text, 0, -1000)
	// draw centered text
	return gc.FillStringAt(text, x-w/2, y)
}

Hi @benoitmasson thanks for the function. There's a method here that can help you compute the size of the string. This method is only available in draw2dimg package. We need functions that computes metrics in draw2d base package.
