IMAGELISTDRAWPARAMS (Windows Embedded CE 6.0)

1/6/2010

This structure contains information about an image list draw operation and is used with the ImageList_DrawIndirect function.

Syntax

typedef struct _IMAGELISTDRAWPARAMS {
  DWORD cbSize;
  HIMAGELIST himl;
  int i;
  HDC hdcDst;
  int x;
  int y;
  int cx;
  int cy;
  int xBitmap;
  int yBitmap;
  COLORREF rgbBk;
  COLORREF rgbFg;
  UINT fStyle;
  DWORD dwRop;
} IMAGELISTDRAWPARAMS, FAR * LPIMAGELISTDRAWPARAMS;

Members

  • cbSize
    Size of this structure, in bytes.
  • himl
    Handle to the image list that contains the image to be drawn.
  • i
    Zero-based index of the image to be drawn.
  • hdcDst
    Handle to the destination device context.
  • xand y
    Specify the coordinates that the image will be drawn at.
  • cxand cy
    Specify the number of pixels to be drawn, relative to the upper-left corner of the drawing operation as specified by xBitmap and yBitmap. If cx and cy are zero, ImageList_DrawIndirect draws the entire valid section. The function does not ensure that the parameters are valid.
  • xBitmapand yBitmap
    Specify the coordinates that specify the upper-left corner of the drawing operation with respect to the image itself. Pixels of the image that are to the left of xBitmap and above yBitmap are not drawn.
  • rgbBk
    Image background color. It can be an application-defined RGB value or one of the following values.

    Value Description

    CLR_DEFAULT

    Default background color. The image is drawn using the image list background color.

    CLR_NONE

    No background color. The image is drawn transparently.

    This parameter is used only if the image list identified by himl was created with the ILC_MASK value.

  • rgbFg
    Image foreground color. It is an application-defined RGB value or one of the following values.

    Value Description

    CLR_DEFAULT

    Default foreground color. The image is drawn using the system highlight color as the foreground color.

    CLR_NONE

    No blend color. The image is blended with the color of the destination device context.

    This parameter is used only if fStyle includes the ILD_BLEND25 or ILD_BLEND50 flag.

  • fStyle
    Flag that specifies the drawing style and, optionally, the overlay image. It can be a combination of one or more of the following values.

    Value Description

    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_FOCUS

    Same as ILD_BLEND25.

    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_SELECTED

    Same as ILD_BLEND50.

    ILD_BLEND

    Same as ILD_BLEND50.

    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_ROP

    Draws the image using the raster-operation code specified by the dwRop member.

    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.

  • dwRop
    Specifies a raster-operation code. These codes define how the color data for the source rectangle will be combined with the color data for the destination rectangle to achieve the final color. This member is ignored if the fStyle member does not include the ILD_ROP flag.

    Some common raster operation codes are shown in the following table.

    Value Description

    BLACKNESS

    Fills the destination rectangle using the color associated with index 0 in the physical palette. (This color is black for the default physical palette.)

    DSTINVERT

    Inverts the destination rectangle.

    MERGECOPY

    Merges the source rectangle colors with the specified pattern by using the Boolean AND operator.

    MERGEPAINT

    Merges the inverted source rectangle colors with the destination rectangle colors by using the Boolean OR operator.

    NOTSRCCOPY

    Copies the inverted source rectangle to the destination.

    NOTSRCERASE

    Combines the source and destination rectangle colors by using the Boolean OR operator. Inverts the resultant color.

    PATCOPY

    Copies the specified pattern into the destination bitmap.

    PATINVERT

    Combines the specified pattern colors with the destination rectangle colors by using the Boolean XOR operator.

    PATPAINT

    Combines the pattern colors with the inverted source rectangle colors by using the Boolean OR operator. Combines the result with the destination rectangle colors by using the Boolean OR operator.

    SRCAND

    Combines the source and destination rectangle colors by using the Boolean AND operator.

    SRCCOPY

    Copies the source rectangle directly to the destination rectangle.

    SRCERASE

    Combines the destination rectangle's inverted colors with the source rectangle colors by using the Boolean AND operator.

    SRCINVERT

    Combines the source and destination rectangle colors by using the Boolean XOR operator.

    SRCPAINT

    Combines the source and destination rectangle colors by using the Boolean OR operator.

    WHITENESS

    Fills the destination rectangle using the color associated with index 1 in the physical palette. This color is white for the default physical palette.

Remarks

An overlay image is an image that is drawn on top of the primary image specified in the imember of this structure. To specify an overlay image, logically OR the fStyle member with the INDEXTOOVERLAYMASK macro, passing the one-based index of the overlay image in the macro. This image must have been previously specified as an overlay image using the ImageList_SetOverlayImage API.

To extract the overlay image from the fStyle member, use the logical AND to combine fStyle with the ILD_OVERLAYMASK value.
