I’m looking for CCLabelTTF ’s win32 code.

It’s use windows api.

1, Dc.DrawText() to HBitmap.
2, HBitmap copy to CCImage.m_pData, Use the func GetDIBits(), And It’s return err.
3, So … CCImage.m_pData is empty. When it’s draw on the screen, no words, only a empty rect.

More help ?
Thanks.

Hava a look again.

hbitmap create by func CreateBitmap(), bitCount 32, DrawText failed.

hbitmap create by func CreateCompatibleBitmap(), DrawText succ.
But, hbitmap ’s bitCount is 1.

So, hbitmap copy to CCImage.m_pData have some mistake. CCImage ’s bitCount is 32.

ok, I find out how to fix it.

Edit win32/ccimage.cpp :

m_hBmp = CreateBitmap(nWidth, nHeight, 1, 32, NULL);
Change to :
m_hBmp = CreateCompatibleBitmap(m_hDC, nWidth, nHeight);

Add
bi.bmiHeader.biBitCount = 32;
Before
GetDIBits(dc.getDC(), dc.getBitmap(), 0, m_nHeight, m_pData, (LPBITMAPINFO)&bi, DIB_RGB_COLORS);

If you have the same bug like me.
You can try this way.

Good luck.
