SHGetImageList function (shellapi.h)
Retrieves an image list.
SHSTDAPI SHGetImageList( int iImageList, REFIID riid, void **ppvObj );
The image type contained in the list. One of the following values:
0x0. The image size is normally 32x32 pixels. However, if the Use large icons option is selected from the Effects section of the Appearance tab in Display Properties, the image is 48x48 pixels.
0x1. These images are the Shell standard small icon size of 16x16, but the size can be customized by the user.
0x2. These images are the Shell standard extra-large icon size. This is typically 48x48, but the size can be customized by the user.
0x3. These images are the size specified by GetSystemMetrics called with SM_CXSMICON and GetSystemMetrics called with SM_CYSMICON.
0x4. Windows Vista and later. The image is normally 256x256 pixels.
The largest valid flag value, for validation purposes.
Reference to the image list interface identifier, normally IID_IImageList.
When this method returns, contains the interface pointer requested in riid. This is typically IImageList.
If this function succeeds, it returns S_OK. Otherwise, it returns an HRESULT error code.
The IImageList pointer type, such as that returned in the ppv parameter, can be cast as an HIMAGELIST as needed; for example, for use in a list view. Conversely, an HIMAGELIST can be cast as a pointer to an IImageList.
As of Windows Vista, SHIL_SMALL, SHIL_LARGE, and SHIL_EXTRALARGE scale with dots per inch (dpi) if the process is marked as dpi-aware. To set these types to be dpi-aware, call SetProcessDPIAware. SHIL_JUMBO is fixed at 256 pixels regardless of the dpi-aware setting.
