Since I haven't found out how to report bugs for this package, I am posting
this here.
Changing the color of Text elements in a Hieroglyph image like this:
text {attributes = plain {strokeRGBA = opaque blue}}
does not work correctly. Instead, the color used for the text is the one of the
previously drawn element. With the little knowledge I have about cairo, it
seems that the bug is in the renderPrimitive function in Cairo.hs where the
order of Cairo.setSourceRGBA and Cairo.showText is wrong. Something like this
seems to work:
renderPrimitive _ s0 (Text str (Point ox oy) state) = do
applyAttributeDelta s0 state
Cairo.moveTo ox oy
let (sr,sg,sb,sa) = colourToTuple . strokeRGBA $ state
when (outlined state) $
Cairo.setSourceRGBA sr sg sb sa
Cairo.showText str
when (clipped state) $ Cairo.clip
return state
By the way, for the complete newbie that I am, is there a standard way to
report bugs for a package from Hackage?
