Thanks for testing.  :)

Ok. I've updated BGRABitmap on subversion, now in TBGRAFreeTypeDrawer, you have a CreateTextEffect function.

or the font from resource stream still can be used somehow?

Ok. Here is a patch to add a font from a stream into a font collection.

Can you give it a try ?


Ok now I got some range check errors, when running LazUtils with range check option.

It appears that variable types are not consistent with loading instruction from the frame buffer.

Can you post your test program?

Hm. Note that:
1) Init procedure is redundant, since class members are auto-zeroed on construction.
2) TFreeTypeFontCollection.AddStream has 90% common code with AddFile.

I could fix both problems myself, but I need a test :)

Sorry about that.

Here is test program for AddStream.

Note that you need to copy in timesi.ttf (Times New Roman Italic) and arial.ttf (Arial Regular).

Finally, I got everything working.

Correct approach was to create a default font collection,
add several fonts into it from resource stream, set this
collection as default one, and select each font via

--- Code: ---xxx.FontName
--- End code ---
referring to its internal name (not file name nor resource name).

Also, too many ways to draw text make things a bit complicated
for beginners. These ones are:

--- Code: ---BGRABitmap.TextOut (...)
BGRAFreeTypeDrawer.DrawText (...)
BGRAVectorizedFontRenderer.TextOut (...)
BGRATextEffect.Draw (...)
--- End code ---

Now I use the 4th variant, but it could be interesting to learn
the difference. What I discovered for now:
1) can draw shadow, can't use stream font;
2) can't draw shadow, can use stream font;
3) can draw shadow, can't use stream font;
4) can draw shadow, can use stream font.

Hope it will be useful to know that for somebody.
Thank you again for your inestimable work!  8)
