]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.
Module: aspose.imaging.fileformats.emf.emf.records
Full Name: aspose.imaging.fileformats.emf.emf.records.EmfAlphaBlend
Inheritance: EmfBitmapRecordType
Constructors
| Name | Description |
|---|---|
| EmfAlphaBlend(source) | Initializes a new instance of the EmfAlphaBlend class. |
Properties
| Name | Type | Access | Description |
|---|---|---|---|
| bk_src_argb_32_color | int | r/w | Gets or sets a WMF ColorRef object ([MS-WMF] section 2.2.2.8 that specifies the background color of the source bitmap. |
| blend_function | EmfBlendFunction | r/w | Gets or sets a structure that specifies the blending operations for source and destination bitmaps |
| bounds | Rectangle | r/w | Gets or sets a WMF RectL object ([MS-WMF] section 2.2.2.19) that defines the destination bounding rectangle in device units. |
| cx_dest | int | r/w | Gets or sets a 32-bit signed integer that specifies the logical width of the destination rectangle. This value MUST be greater than zero. |
| cx_src | int | r/w | Gets or sets a 32-bit signed integer that specifies the logical width of the source rectangle. This value MUST be greater than zero. |
| cy_dest | int | r/w | Gets or sets a 32-bit signed integer that specifies the logical height of the destination rectangle. This value MUST be greater than zero. |
| cy_src | int | r/w | Gets or sets a 32-bit signed integer that specifies the logical height of the source rectangle. This value MUST be greater than zero. |
| size | int | r/w | Gets or sets the size of the record |
| source_bitmap | WmfDeviceIndependentBitmap | r/w | Gets 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. |
| type | EmfRecordType | r/w | Gets or sets the type. |
| usage_src | EmfDibColors | r/w | Gets 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_dest | int | r/w | Gets or sets a 32-bit signed integer that specifies the logical x-coordinate of the upper-left corner of the destination rectangle. |
| x_src | int | r/w | Gets or sets a 32-bit signed integer that specifies the logical x-coordinate of the upper-left corner of the source rectangle. |
| xform_sr | Matrix | r/w | Gets 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_dest | int | r/w | Gets or sets a 32-bit signed integer that specifies the logical y-coordinate of the upper-left corner of the destination rectangle. |
| y_src | int | r/w | Gets or sets a 32-bit signed integer that specifies the logical y-coordinate of the upper-left corner of the source rectangle. |
