ExpandRow(ushort[],IntPtr,int,int) Method

Summary

Performs buffer-to-buffer RLE decompression of unmanaged 1-bit image data.

Syntax

C++

[CLSCompliantAttribute(false)] 
public static void ExpandRow( 
   ushort[] runBuffer, 
   IntPtr buffer, 
   int column, 
   int width 
)

<CLSCompliantAttribute(False)> 
Public Overloads Shared Sub ExpandRow( _ 
   ByVal runBuffer() As UShort, _ 
   ByVal buffer As IntPtr, _ 
   ByVal column As Integer, _ 
   ByVal width As Integer _ 
)

[CLSCompliantAttribute(false)] 
public: 
static void ExpandRow(  
   array<ushort>^ runBuffer, 
   IntPtr buffer, 
   int column, 
   int width 
)

Parameters

runBuffer
The input buffer containing 1-bit compressed image data.

buffer
The unmanaged output buffer, which is to be filled with 1-bit image data.

column
Column offset within the row to be processed. The method skips this many pixels before it begins processing.

width
The number of pixels to process.

Remarks

Use this method to process all or part of a single line of image data. This method is available in the Document/Medical Toolkits.

This function is useful for working with 1-bit images that are loaded in their compressed formats for faster loading and display. For more information, refer to Speeding Up 1-Bit Documents.

Example

For an example, refer to SetRowColumnCompressed.
