'Declaration
 
Public Overloads MustOverride Function Rasterize( _
   ByVal bitDepth As Integer, _
   ByVal resolutionX As Integer, _

'Usage
 
Dim instance As ImGearVectorPage
Dim bitDepth As Integer
Dim resolutionX As Integer
Dim resolutionY As Integer
Dim value As ImGearRasterPage
 
value = instance.Rasterize(bitDepth, resolutionX, resolutionY)

public abstract ImGearRasterPage Rasterize( 
   int bitDepth,
   int resolutionX,
   int resolutionY
)

public: abstract ImGearRasterPage* Rasterize( 
   int bitDepth,
   int resolutionX,
   int resolutionY
)

public:
abstract ImGearRasterPage^ Rasterize( 
   int bitDepth,
   int resolutionX,
   int resolutionY
)

Parameters

bitDepth: The bit depth of resulting raster page.
resolutionX: This parameter specifies the horizontal resolution in dots-per-inch during the vector page conversion into a raster image. The greater this value, the higher the quality of the raster image you get after rasterization. The DIB of the output raster image has this value as an X resolution.
resolutionY: This parameter specifies the vertical resolution in dots-per-inch during the vector page conversion into the raster image. The greater this value, the higher the quality of the raster image you get after rasterization. The DIB of the output raster image has this value as an Y resolution.

Return Value

ImGearRasterPage class instance with rasterized vector data.

The support level for parameter bitDepth depends on each particular vector format, i.e it may either just ignore it, or consider limited set of bit depths. Please see below the table of Vector formats, that describes how they handle the parameter bitDepth.
