SetRowColumnCompressed(IntPtr,IntPtr,int,int,int) Method

Summary
Puts a row (or part of a row) of 1-bit compressed data from an unmanaged memory buffer to an image that is maintained in its compressed format.
Syntax
C#
C++/CLI
Java
Python
public int SetRowColumnCompressed( 
   IntPtr workBuffer, 
   IntPtr runBuffer, 
   int row, 
   int column, 
   int width 
) 
public int setRowColumnCompressed( 
  byte workBuffer[],  
  short runBuffer[],  
  int row,  
  int column,  
  int width 
) 
public: 
int SetRowColumnCompressed(  
   IntPtr workBuffer, 
   IntPtr runBuffer, 
   int row, 
   int column, 
   int width 
)  
def SetRowColumnCompressed(self,workBuffer,runBuffer,row,column,width): 

Parameters

workBuffer
Pointer to optional work unmanaged memory buffer. Allocating the work buffer speeds processing if you call this method more than once, because if you do not allocate a work buffer, the method allocates and frees a temporary buffer each time it is called. The size of this buffer should be the same as the image's BytesPerLine property. Pass IntPtr.Zero for  workBuffer if you do not want to use the work buffer

runBuffer
Pointer to input unmanaged memory buffer, which contains 1-bit compressed image data.

row
The number of the row to update. The first row is 0, and the last row is 1 less than the image height.

column
The column offset within the row to update. The first column offset is 0, and the last column offset is 1 less than the image width.

width
The number of pixels to retrieve.

Return Value

The number of pixels processed.

Remarks

This method is available in the (Document/Medical only) Toolkits.

This method is useful for working with 1-bit images that are loaded in their compressed formats for faster loading and display.
