ResizeBuffer(IntPtr,int,int) Method

Summary

Resizes an unmanaged buffer to the new size specified with the Start method.

Syntax

C++

public void ResizeBuffer( 
   IntPtr buffer, 
   int row, 
   int bitsPerPixel 
)

Public Overloads Sub ResizeBuffer( _ 
   ByVal buffer As IntPtr, _ 
   ByVal row As Integer, _ 
   ByVal bitsPerPixel As Integer _ 
)

public: 
void ResizeBuffer(  
   IntPtr buffer, 
   int row, 
   int bitsPerPixel 
)

Parameters

buffer
The unmanaged buffer containing the original scanline to be resized.

row
Current row of the original bitmap.

bitsPerPixel
Bits per pixel, which is the same for the original and the resized bitmap.

Remarks

buffer contains the buffer containing a line from the original image to be resized. Your code must allocate the buffer and copy the data into it before calling this method.

The same buffer holds the data before and after it is resized. Therefore, the buffer must be big enough to hold whichever is larger. (The original line is larger when reducing an image; the resulting line is larger when enlarging the image.)

Before calling this function, you must call the Start method.

When all lines have been processed, you must call the Stop method.
