// Function Name: ImageList_LoadImageAndMirror
|
|
//
|
|
// Purpose: This function creates an image list from the specified bitmap or icon resource.
|
|
//
|
|
// Arguments:
|
|
// hi [in] Handle to the instance of an application or DLL that contains an image.
|
|
// lpbmp [in] Long pointer to the image to load.
|
|
// If the uFlags parameter includes LR_LOADFROMFILE, lpbmp is the address
|
|
// of a null-terminated string that names the file containing the image to load.
|
|
//
|
|
// If the hi parameter is non-NULL and LR_LOADFROMFILE is not specified, lpbmp is the
|
|
// address of a null-terminated string that contains the name of the image resource in the hi module.
|
|
//
|
|
// If hi is NULL and LR_LOADFROMFILE is not specified, the low-order word of this
|
|
// parameter must be the identifier of an OEM image to load. To create this value, use the
|
|
// MAKEINTRESOURCE macro with one of the OEM image identifiers defined in Winuser.h.
|
|
// These identifiers have the following prefixes:
|
|
// OBM_ for OEM bitmaps
|
|
// OIC_ for OEM icons
|
|
//
|
|
// cx [in] Width of each image. The height of each image and the initial number of images are inferred
|
|
// by the dimensions of the specified resource.
|
|
// cGrow [in] Number of images by which the image list can grow when the system needs to make room for new
|
|
// images. This parameter represents the number of new images that the resized image list can contain.
|
|
// crMask [in] Color used to generate a mask. Each pixel of this color in the specified bitmap or icon is changed to
|
|
// black, and the corresponding bit in the mask is set to 1. If this parameter is the CLR_NONE value,
|
|
// no mask is generated. If this parameter is the CLR_DEFAULT value, the color of the pixel at the
|
|
// upper-left corner of the image is treated as the mask color.
|
|
// uType [in] Flag that specifies the type of image to load. This parameter can be one of the following values:
|
|
// IMAGE_BITMAP Loads a bitmap.
|
|
// IMAGE_ICON Loads an icon.
|
|
// uFlags [in] Unsupported; set to 0.
|
|
//
|
|
// Returns:
|
|
// The handle to the image list indicates success. NULL indicates failure.
