The problem with both of these solutions is that I need the bounding
rectangle to be in a Graphics[] expression because I'm creating several
of these text filled boxes at arbitrary offsets. I'm trying to create
something similar to Graph[] (hopefully using it's embedding functions)
but instead of vertexes I want to create collections of boxes containing
text. However Mathematica seems to render text independently of the
coordinate range of the graphic. For example, these two expressions
produce identical output:
Graphics[{
Text[Style["Test", 12]],
Circle[{0, 0}, 1]
}
]
Graphics[{
Text[Style["Test", 12]],
Circle[{0, 0}, 100]
}
]
I found something close to what I want to do, but it's ugly because the
graphics don't scale nicely:
Graphics[{
FaceForm[], EdgeForm[Black],
Raster[Reverse[Rasterize["Hello", "Data"]], {{0, 0}, {100, 16}}],
Rectangle[{0, 0}, {100, 16}]
}
]
But I would have to hope that surely there is some way to put Text[] in
Graphics[] such that the size of the text is proportional to the visible
coordinate range of the Graphics[]. Even if I could only find the size
of the text in a given image I could then scale it as needed. I tried
using Rasterize[string,"RasterSize"] but I couldn't figure out how to
make it work. Any ideas along that line? I'm hoping that I'm just
missing something obvious that I've overlooked in Mathematica's big API...
Thanks,
Michael
