This method retrieves the RGB values and palette number of the specified pixel in the Device Independent Bitmap (DIB). This method is equivalent to the GetDibPixel method but can be used in scripting languages that require variant types.
Parameters
| Name | Explanation |
|---|---|
| DibNo | The identification number of the DIB as retrieved from the StartDibAccessVariant method. |
| x, y | The x,y coordinates of the specified pixel |
| PalNo | The palette number of the specified pixel |
| Red | The red component of the RGB value of the specified pixel |
| Green | The green component of the RGB value of the specified pixel |
| Blue | The blue component of the RGB value of the specified pixel |
Return Value
Returns True (nonzero) if successful, otherwise returns False (0).
Explanation
The GetDibPixelVariant method
retrieves the RGB values and palette number of the specified pixel
in the Device Independent Bitmap (DIB). This method is equivalent
to the GetDibPixel method but
can be used in scripting languages that require variant types. The
DibNo parameter value must be the same as that retrieved from the
StartDibAccessVariant
method. For 1, 4, and 8 bit images, the applicable values are set
in the PalNo parameter. For 16, 24, and 32 bit images, the
applicable values are set in the Red, Green, and Blue
parameters
To access the DIB and manipulate pixel data, you must use the
following methods as a group:
StartDibAccessVariant
|
GetDibPixelVariant, SetDibPixelVariant
|
EndDibAccessVariant
