Hi,
I did not write several parts of this myself. a2fFont is mainly written by
someone else.
So i agree that the next is a bit confusing.
enum a2dFontAlignment
{
// wxCENTRE
wxMINX = wxLEFT,
wxMAXX = wxRIGHT,
wxMINY = wxBOTTOM,
wxMAXY = wxTOP,
wxBBOX = 0x100,
a2dDEFAULT_ALIGNMENT = wxTOP | wxLEFT | wxBBOX
};
And i think we best make something which comes closest to SVG.
Get rid of the wxWidgets wxLEFT etc., instead make one alignment enum, with all
that is needed.
So indeed thing like:
enum a2dFontAlignment
{
a2dALIGN_LEFT
a2dALIGN_RIGHT
a2dALIGN_VERTICAL_CENTER
a2dALIGN_VERTICAL_BASELINE
a2dALIGN_VERTICAL_BOTTOM
a2dALIGN_VERTICAL_TOP
a2dALIGN_HORIZONTAL_CENTER
a2dALIGN_BBOX
}
would be better. Or whatever is more close to SVG would be oke also.
If you think you can do it, i am all for it.
But functions like this need to understand it too, so not that easy.
ic.GetDrawer2D()->DrawText( left, x, y + line * up * (GetLineHeight() +
m_linespace), m_alignment, !GetDrawFrame() && GetBackGround() );
m_font.GetTextExtent( left, ic.GetDrawer2D()->GetYaxis(), wxLEFT|wxTOP|wxBBOX,
&w );
It seems that the alignment is towards a line of text and how it is positioned
relative to the a2dText position. The rest of the lines follow from that.
I wonder ifSVG thinks like thata, or in multiple text lines alignment??

Looking over the a2dText code, the alignment uses wxLEFT, wxRIGHT,
wxCENTER, etc. for text alignment. However, this can result in the
inability to set vertical center alignment, as wxCenter is used for
both horizontal and vertical alignment. Suggested change: use
wxALIGN_LEFT, wxALIGN_RIGHT, wxALIGN_VERTICAL_CENTER, etc., while
mapping wxLEFT, wxRIGHT, etc. to these ALIGN versions (with wxCENTER =
wxALIGN_HORIZONTAL_CENTER) in SetAlignment(...).
Vertical centering doesn't seem to be actually implemented in the code
from what I've seen.
