Hi there,

while appreciating the changes in the imagemanager in reducing the amount of needed handles for storing all the content i�m missing some functionality.
In Toolkit 10.4 it was possible to extract the hbitmap or hicon from the imagemanager, depending on the way the image was stored in the imagemanger, with the following code.

    CXTPImageManagerIcon icon = XTPImageManager()->GetImage(IDC_MYICON, 16);
    CXTPImageManagerIconHandle xtphIcon = icon.GetIcon();
    HBITMAP hBitmap = xtphIcon.GetBitmap();
    HICON hIcon = xtphIcon.GetIcon();

Now it is absolutly impossible to get these informations from the imagemanager. This leads to the need of storing hbitmaps and hicons in seperate stores having the side effect of even more handle allocations.

Why doesn�t the Imagemanager store appropriate functionality to create hbitmap and hicon from it�s internal store.

Am i missing something?

Thanks for reading so far, hoping for your answers :)

Jan

Hi,

Just copy it to som fre handle:

CXTPImageManagerIconHandle xtphIcon = icon.GetIcon();

CXTPImageManagerIconHandle hIconFree;

hIconFree.CopyHandle(xtphIcon);

or don't use resources feature - pImageManager->m_bUseResources = FALSE;

Hi Oleg,

i need it the other way round. I don�t want to copy a HBITMAP to the imagemanager, i need to get a HBITMAP or HICON FROM the Imagemanager. Even telling the imagemanager not to use ressources is the opposit of what i need and want.

Your solution ist:
// Summary:
// Copies data from an HBITMAP or CXTPImageManagerIconHandle object

I need functions to get the imagemanager to create a hicon or hbitmap of it�s internal image in memory and i�m wondering why the imagemanager doesn�t offer these.

Best regards,

Jan

Sorry. Got it. Sample for others following this thread...

    CXTPImageManagerIcon* pXTPIcon = XTPImageManager()->GetImage(MYICONID, 16);
    CXTPImageManagerIconHandle cXTPIconHandle = pXTPIcon->GetIcon(xtpImageNormal);
    CXTPImageManagerIconHandle cXTPnewIconHandle;
    cXTPnewIconHandle.CopyHandle(cXTPIconHandle);
    HBITMAP hBitmap = cXTPnewIconHandle.GetBitmap();

hBitmap can be used for creating an hIcon if needed using this code:

HICON Helper::CreateAlphaIcon(HBITMAP hBitmap, const CSize& size)
{
    HICON hIcon = NULL;
    CBitmap bmpResample;
    CImageList list;

    if (XTPImageManager()->IsAlphaIconsImageListSupported())
    {
        list.Create(size.cx, size.cy, ILC_COLOR32, 0, 1);
        bmpResample.Attach(hBitmap);
        list.Add(&bmpResample, (CBitmap*)NULL);
    }
    else
    {
        list.Create(size.cx, size.cy, ILC_MASK | ILC_COLOR24, 0, 1);
        bmpResample.Attach(CXTPImageManager::ResampleAlphaLayer(hBitmap, RGB(255,255,255)));
        list.Add(&bmpResample, RGB(255,255,255));
    }
    hIcon = list.ExtractIcon(0);
    bmpResample.Detach();

    return hIcon;
}

Thanks oleg :)
