Hi,

Is there a (documented) way to extract a glyph from the skin definition (through a specific section name)?

What I'm trying to achieve is to allow the users to define application-specific glyphs (eg. the bitmap for an “Open file” speedbutton) inside the skin itself. Just to be clear, I'm not speaking about the control's skin here, but really about the glyph it uses. The ideal for me would be to extract all those app-specific glyphs into an image list so that I just have to update it whenever the skin changes.

For now I didn't find a way to do it, maybe I missed something obvious… anyone got a hint?

Ok, I finally figured out how to achieve that.

1) Obviously, define a new section for a specific glyph
2) Code (it's C++ but you Delphi people should have no problems to port it):

CODE

// imgList is a TsAlphaImageList
imgList->AcBeginUpdate();
imgList->Clear();
imgList->Items->Clear();

// For each glyph…
std::auto_ptr bmp(sGraphUtils::CreateBmp32(imgList->Width,imgList->Height));
sGraphUtils::PaintSection(bmp.get(),”MY_GLYPH_SECTION”,””,0,skinProvider->SkinData->SkinManager,TPoint(0,0),SomeColor);
imgList->Add(bmp.get(),0);
bmp.reset();

imgList->AcEndUpdate();

Maybe there is a more efficient way, but at least that works.

Hello

You can have directly access to Bitmap (if this image was contained in separated Bmp file).
Here is a code :

CODE

const
  SectionName = 'SectionName';
var
  SkinIndex, ImgIndex : integer;
begin
  SkinIndex := sSkinManager1.GetSkinIndex(SectionName);
  if sSkinManager1.IsValidSkinIndex(SkinIndex) then begin
    ImgIndex := sSkinManager1.GetMaskIndex(SectionName, 'BORDERSMASK');
    if sSkinManager1.IsValidImgIndex(ImgIndex) then begin
      sSkinManager1.ma[ImgIndex].Bmp <- This a the image
    end;
  end;
end;

Maybe this way will be faster.

Thanks Serge, I will try that.

Hi,

I'm still stuck on this. Your solution gives me a raw bitmap, so I have to recombine the alpha mask by myself which isn't quite satisfying. Moreover, it doesn't benefit from ASkin's capability to use borders (so that the glyph is extensible), textures and what not, which would be a really neat feature to add to the glyphs. Anyway I also need those features for other uses.

And when it comes to my own solution that I already posted, it has a serious drawback : it *needs* a background color, but I want the resulting bitmap to have alpha transparency (ie. “background” color is transparent) which I can't achieve.

In other words, I'm trying to find a way to do something as simple as CreateAlphaBitmap32OrPngFromSkin(skinManager, skinSection, state, sizeX, sizeY, destinationBitmap).

Any ideas ?

I'll make a small demo soon

Hello
Here is a demo, try it please.
Options.dat changing is not required here. New way is much easier.

Thank you very much for the demo Serge, this is exactly what I need ! Perfect.

Have a nice day and keep up the good work.
