Property Documentation

ULONG RW AlphaBlend

Specifies an alpha transparency value to be used for drawing.

If you set value to 0, it is assumed that the option is not used. Minumum value: 0. Maximum value: 255. Default value: 0.

Since:

1.1.12.

ULONG RW CopyMode

Specifies the copy mode for the control.

These mode defines how the color data for the source is to be combined with the color data for the destination to calculate the final color.

This parameter can be a one of the following values (dest - the color of the destination, source - the color of the source):

• SRCCOPY dest = source
• SRCPAINT dest = source OR dest
• SRCAND dest = source AND dest
• SRCINVERT dest = source XOR dest
• SRCERASE dest = source AND (NOT dest)
• NOTSRCCOPY dest = (NOT source)
• NOTSRCERASE dest = (NOT src) AND (NOT dest)
• MERGECOPY dest = (source AND pattern)
• MERGEPAINT dest = (NOT source) OR dest
• PATCOPY dest = pattern
• PATPAINT dest = DPSnoo
• PATINVERT dest = pattern XOR dest
• DSTINVERT dest = (NOT dest)
• BLACKNESS dest = BLACK
• WHITENESS dest = WHITE

Default value: SRCCOPY.

ULONG RW DrawType

Specifies the draw mode for the control.

This parameter can be a one of the following values:

• DI_DRAW Draw the image using image size.
• DI_STRETCH Draw the image stretched in the control.
• DI_CENTER Draw the image centered in the control.
• DI_PROPORTIONAL_STRETCH Draw the image proportially stretched in the control.

Default value: DI_DRAW.

ULONG R ImageHeight

Returns source image height.

Since:

1.1.10.

ULONG R ImageWidth

Returns source image width.

Since:

1.1.10.
