Class EmfMaskBlt

Namespace: Aspose.Imaging.FileFormats.Emf.Emf.Records
Assembly: Aspose.Imaging.dll (25.7.0)

The EMR_MASKBLT record specifies a block transfer of pixels from a source bitmap to a destinationrectangle, optionally in combination with a brush pattern and with the application of a color maskbitmap, according to specified foreground and background raster operations.

public sealed class EmfMaskBlt : EmfBitmapRecordType
   {
       public int SrcX;
       public int SrcY;
       public int Width;
       public int Height;
       public bool Rop;
       public short BltSequence(Graphics g, Rectangle bounds)
       {
           var srcRect = new Rectangle(SrcX, SrcY, Width, Height);
           var dstRect = new Rectangle(bounds.X, bounds.Y, bounds.Width, bounds.Height);

Constructors

EmfMaskBlt(EmfRecord)

Initializes a new instance of the Aspose.Imaging.FileFormats.Emf.Emf.Records.EmfMaskBlt class.

public EmfMaskBlt(EmfRecord source)
{
}

Parameters

source EmfRecord

The source.

Properties

Argb32BkColorSrc

Gets or sets a WMF ColorRef object ([MS-WMF] section 2.2.2.8 that specifies thebackground color of the source bitmap.

public int Argb32BkColorSrc
    {
        get;
        set;
    }

Property Value

int

Bounds

Gets or sets a WMF RectL object ([MS-WMF] section 2.2.2.19) that defines thedestination bounding rectangle in device units.

public Rectangle Bounds
   {
      get;
      set;
   }

Property Value

Rectangle

CxDest

Gets or sets a 32-bit signed integer that specifies the logical width of the destination rectangle.

public int CxDest
   {
      get;
      set;
   }

Property Value

int

CyDest

Gets or sets a 32-bit signed integer that specifies the logical height of the destination rectangle.

public int CyDest
{
    get;
    set;
}

Property Value

int

MaskBitmap

Gets or sets a buffer containing the mask bitmaps, which are notrequired to be contiguous with the fixed portion of the EMR_MASKBLT record or with eachother. Accordingly, fields in this buffer that are labeled “UndefinedSpace” are optional andMUST be ignored.

public WmfDeviceIndendentBitmap MaskBitmap
   {
      get;
      set;
   }

Property Value

WmfDeviceIndependentBitmap

Rop4

Gets or sets a quaternary raster operation, which specifies ternary raster operations forthe foreground and background colors of a bitmap. These values define how the color data ofthe source rectangle is to be combined with the color data of the destination rectangle.

public EmfRop4 Rop4
   {
      get;
      set;
   }

Property Value

EmfRop4

SourceBitmap

Gets or sets a buffer containing the source bitmaps, which are notrequired to be contiguous with the fixed portion of the EMR_MASKBLT record or with eachother. Accordingly, fields in this buffer that are labeled “UndefinedSpace” are optional andMUST be ignored.

public WmfDeviceIndependentBitmap SourceBitmap
    {
        get;
        set;
    }

Property Value

WmfDeviceIndependentBitmap

UsageMask

Gets or sets a 32-bit unsigned integer that specifies how to interpret values in thecolor table in the mask bitmap header. This value MUST be in the DIBColors enumeration.

      set;
   }

Property Value

EmfDibColors

UsageSrc

Gets or sets a 32-bit unsigned integer that specifies how to interpret values in thecolor table in the source bitmap header. This value MUST be in the DIBColors enumeration (section 2.1.9).
