Local fontsize renders inconsistentl on diffrent backends

[jeffreyrosenbluth]

Local font scaling on svg, cairo, rasterific and canvas produced different results.
rasterific and canvas are similar.

eff = text "F" <> square 1

 example = hcat
   [eff, eff # scale 2, eff # scaleX 2, eff # scaleY 2, eff # rotateBy (1/12)]
         # fontSize (Local 1)

I'm getting reasonably consistent results:

svg

rasterific

pgf

html5

Note that the fontSize (local 1) doesn't have the scales applied because it's applied after the transforms (I think this is different from old behaviour). If the font size is transformed too I get these:

svg

rasterific

pgf

html5

I haven't got Cairo installed here so I haven't tested it. What are you seeing?

Sorry, I'm blind -- SVG is clearly wrong. I even made an issue about it diagrams/diagrams-svg#66. I think it has something to do with the weird way SVG handles font-size precedence. I didn't look at it properly.

Ah, I didn't realize the semantics changed. Thanks for putting together this comparison.
So the only thing broken is diagrams-svg. I guess we should change the user manual example to

eff = text "F" <> square 1 # fontSize (Local 1)
 example = hcat
   [eff, eff # scale 2, eff # scaleX 2, eff # scaleY 2, eff # rotateBy (1/12)]

In you're example you're only changing the font size of the square :)

Note that the default font size is local 1 anyway, but it seems like a good idea to make it explicit in case it ever changes.

Aha, I was confused, thanks all!

Still not sure his is correct. What should this look like?

eff = text "F" <> square 1 # fontSize (Normalized 0.1)
 example = hcat
   [eff, eff # scale 2, eff # scaleX 2, eff # scaleY 2, eff # rotateBy (1/12)]

Never mind, I was missing the parenthesis.
eff = (text "F" <> square 1) # fontSize (Normalized 0.1)
