Parameters
himl
Handle to the
image list
i
Index of the
image to draw.
hdcDst
Handle to the
destination device context.
x
Specifies the
x-coordinate at which to draw within the specified device context.
y
Specifies the
y-coordinate at which to draw within the specified device context.
dx
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
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
Background
color of the image. This parameter can be an application-defined RGB value or one of the following
values:
|
Value |
Meaning |
|
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
Foreground
color of the image. This parameter can be an application-defined RGB value or one of the following
values:
|
Value |
Meaning |
|
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
Flag
specifying the drawing style. This parameter can be one or more of the
following values:
|
Value |
Meaning |
|
ILD_BLEND25,
|
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,
|
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
If the
function succeeds, the return value is nonzero.
If the
function fails, the return value is zero.
