Syntax
BOOL WINAPI ImageList_DrawEx(HIMAGELIST himl, int i,
HDC hdcDst, int x, int y, int dx, int dy, COLORREF rgbBk,
COLORREF rgbFg, UINT fStyle);
Parameters
himl
[in] Handle to the image list.
i
[in] Index of the image to draw.
hdcDst
[in] Handle to the destination device context.
x
[in] Specifies the x-coordinate at which to draw within the specified device context.
y
[in] Specifies the y-coordinate at which to draw within the specified device context.
dx
[in] Specifies the width of the portion of the image to draw relative to the upper-left corner of the image. If dx and dy are zero, the function draws the entire image. The function does not ensure that the parameters are valid.
dy
[in] Specifies the height of the portion of the image to draw, relative to the upper-left corner of the image. If dx and dy are zero, the function draws the entire image. The function does not ensure that the parameters are valid.
rgbBk
[in] Background color of the image. This parameter can be an application-defined RGB value or one of the following values:
| Value | Description |
| CLR_NONE | No background color. The image is drawn transparently. |
| CLR_DEFAULT | Default background color. The image is drawn using the background color of the image list. |
This parameter is used only if the image list identified by himl was created with the ILC_MASK value.
rgbFg
[in] Foreground color of the image. This parameter can be an application-defined RGB value or one of the following values:
| Value | Description |
| CLR_NONE | No blend color. The image is blended with the color of the destination device context. |
| CLR_DEFAULT | Default foreground color. The image is drawn using the system highlight color as the foreground color. |
This parameter is used only if fStyle includes the ILD_BLEND25 or ILD_BLEND50 value.
fStyle
[in] Specifies the drawing style and, optionally, the overlay image. For information about specifying an overlay image index, see the comments section at the end of this topic. This parameter can be a combination of an overlay image index and one or more of the following values:
| Value | Description |
| ILD_BLEND25, ILD_FOCUS | Draws the image, blending 25 percent with the blend color specified by rgbFG. This value has no effect if the image list does not contain a mask. |
| ILD_BLEND50, ILD_SELECTED, ILD_BLEND | Draws the image, blending 50 percent with the blend color specified by rgbFG. This value has no effect if the image list does not contain a mask. |
| ILD_MASK | Draws the mask. |
| ILD_NORMAL | Draws the image using the background color for the image list. If the background color is the CLR_NONE value, the image is drawn transparently using the mask. |
| ILD_TRANSPARENT | Draws the image transparently using the mask, regardless of the background color. This value has no effect if the image list does not contain a mask. |
Return Values
Nonzero indicates success. Zero indicates failure.
Remarks
An overlay image is drawn transparently over the primary image specified in the i parameter. To specify an overlay image in the fStyle parameter, use the INDEXTOOVERLAYMASK macro to shift the one-based index of the overlay image. Use the OR operator to logically combine the return value of the macro with the drawing style flags specified in the fStyle parameter. You must first specify this image as an overlay image by using the ImageList_SetOverlayImage function.
