Git master fbca2a8df42c88de193c4a2e267d98ec9f6aabd3 has:
"
   function getglyph(const abitmap: tmaskedbitmap; const achar: card32;
const acolor: colorty = cl_text): boolean;
 //empty bitmap in case of error, retruns true if ok
   function getglyph(const abitmap: tmaskedbitmap; const achar: card32;
 const aframe: framety; //padding
const acolor: colorty = cl_text): boolean;
 //empty bitmap in case of error, retruns true if ok
   function getcell(const abitmap: tmaskedbitmap; const achar: card32;
const acolor: colorty = cl_text): boolean;
 //empty bitmap in case of error, retruns true if ok
   function getcell(const abitmap: tmaskedbitmap; const achar: card32;
 const aframe: framety; //padding
const acolor: colorty = cl_text): boolean;
 //empty bitmap in case of error, retruns true if ok
"
getcell() returns a bitmap with the height of the font where the glyph is 
placed by fontmetrics.

I assume that the difference is because there are two centre roundings, one by 
placing the glyph in the imagelist and one by drawing the imagelist item in 
the button rect. I did not find different behaviour between painting and 
imagelist centring.

Re: [MSEide-MSEgui-talk] FontAwesome icons - size regression

[Krzysztof]

Could you also add "rotate" option? I think that then we can create
set of images and create sprite animation for spinners. Look at
"spinner" section https://fortawesome.github.io/Font-Awesome/icons/
BTW: Is there any component or example for sprite animation? In
mseuniverse found only blendanimation example. I guess that I can just
drop TTimer and increment imagenr of any TImageList widget

The directory glyphs are placed on the baseline of the font so probably the 
simplest is to cut the baseline:
"
f.left := 1;
f.top := 0;
f.right := 0;
f.bottom := -2;
"
or
"
glyphs.getcell(b.bitmap,ACode,makeframe(1,0,0,-2),AColor);
or
"
glyphs.getcell(b.bitmap,ACode,mf(1,0,0,-2),AColor);
"

Indeed that is better. Result same (or even better) and bitmap smaller. Thanks

[MSEide-MSEgui-talk] SQLDB - can't find bufdataset_parser

[Krzysztof]

Hi Martin,

Why can't use sqldb unit? Get error:
"bufdataset.pas(24,26) Fatal: Cannot find bufdataset_parser used by
BufDataset. Make sure all ppu files of a package are in its output
directory. ppu in wrong
directory=/usr/lib/fpc/2.6.4/units/x86_64-linux/fcl-db/bufdataset_parser.ppu.."

sqldb is FPC package, not Lazarus. Checked with empty console project
and everything is fine. Does MSE force to use own db units? I already
have a lot of units with TSqlQuery and TSQLite3Connection and such
migration is quite time consuming.

Regards
