Color issues withusing CImageList in a Tree control

I've created an 8 bit bmp with some shading for use in a tree control. BMP looks good in the editor but when displayed/used it looks terrible. The color is there but the shading is not

I loaded it like this. I've tried various values besides ILC_COLOR4, including ILC_COLOR but doesn't help

	// Load the status bitmaps
	g_pStatusImageList = new CImageList();
	if (!g_pStatusImageList->Create(IDB_STATUS, 16, 16, ILC_COLOR4))

Open in new window

I used it like this

	
if (!m_ctlTree.Create(
           TVS_HASLINES | TVS_LINESATROOT | TVS_HASBUTTONS | 
           TVS_DISABLEDRAGDROP | TVS_SHOWSELALWAYS,
		   CRect(0, 0, 0, 0), this, IDC_TREECTRL)) {
		g_pError->Add("Problem creating tree control!");      
		return 0;
	}

	m_ctlTree.SetBkColor(GetSysColor(COLOR_WINDOW));
	m_ctlTree.SetImageList(g_pStatusImageList, TVSIL_NORMAL);

Hi newbie-netter,

IMO you should use ILC_COLOR24 instead. Using ILC_COLOR4 means theimage list uses4 bit per pixel thus it can only have 16 different colors. With ILC_COLOR8 there are 8 bit per pixel which address entries of a 256-color palette. Here you can find a little bit more info about this: http://www.ucancode.net/Visual_C_MFC_Samples/Add-bitmap-to-CImageList-VC-Example.htm

Hope that helps,

That would have been nice if that was it, but that didn't work. I tried ILC_COLOR32 as well. I added a picture of what it looks like in my editor and in my application

Here's how I'm loading the bitmap, forgot to include that the first time

	m_StatusBitmap.LoadBitmap(IDB_STATUS);
	m_pStatusDC->SelectObject( &m_StatusBitmap );
