EmfAlphaBlend Class

Summary: The EMR_ALPHABLEND record specifies a block transfer of pixels from a source bitmap to a
destination rectangle, including alpha transparency data, according to a specified blending operation.

Properties

NameTypeAccessDescription
bk_src_argb_32_colorintr/wGets or sets a WMF ColorRef object ([MS-WMF] section 2.2.2.8 that specifies the
background color of the source bitmap.
blend_functionEmfBlendFunctionr/wGets or sets a structure that specifies the blending operations for source and
destination bitmaps
boundsRectangler/wGets or sets a WMF RectL object ([MS-WMF] section 2.2.2.19) that defines the
destination bounding rectangle in device units.
cx_destintr/wGets or sets a 32-bit signed integer that specifies the logical width of the destination
rectangle. This value MUST be greater than zero.
cx_srcintr/wGets or sets a 32-bit signed integer that specifies the logical width of the source rectangle.
This value MUST be greater than zero.
cy_destintr/wGets or sets a 32-bit signed integer that specifies the logical height of the destination
rectangle. This value MUST be greater than zero.
cy_srcintr/wGets or sets a 32-bit signed integer that specifies the logical height of the source
rectangle. This value MUST be greater than zero.
sizeintr/wGets or sets the size of the record
source_bitmapWmfDeviceIndependentBitmapr/wGets or sets a buffer containing the source bitmap, which is not required to be
contiguous with the fixed portion of the EMR_ALPHABLEND record. Accordingly, fields in this
buffer that are labeled “UndefinedSpace” are optional and MUST be ignored.
typeEmfRecordTyper/wGets or sets the type.
usage_srcEmfDibColorsr/wGets or sets a 32-bit unsigned integer that specifies how to interpret values in the
color table in the source bitmap header. This value MUST be in the DIBColors enumeration (section 2.1.9).
x_destintr/wGets or sets a 32-bit signed integer that specifies the logical x-coordinate of the upper-left
corner of the destination rectangle.
x_srcintr/wGets or sets a 32-bit signed integer that specifies the logical x-coordinate of the upper-left
corner of the source rectangle.
xform_srMatrixr/wGets or sets an XForm object (section 2.2.28) that specifies a world-space to page-space transform to apply to the source bitmap.
y_destintr/wGets or sets a 32-bit signed integer that specifies the logical y-coordinate of the upper-left
corner of the destination rectangle.
y_srcintr/wGets or sets a 32-bit signed integer that specifies the logical y-coordinate of the upper-left
corner of the source rectangle.
