SetRowColumnCompressed(IntPtr,IntPtr,Int32,Int32,Int32) 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
public int SetRowColumnCompressed(IntPtr workBuffer,IntPtr runBuffer,int row,int column,int width)
Public Overloads Function SetRowColumnCompressed( _ByVal workBuffer As IntPtr, _ByVal runBuffer As IntPtr, _ByVal row As Integer, _ByVal column As Integer, _ByVal width As Integer _) As Integer
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)
function Leadtools.RasterImage.SetRowColumnCompressed(IntPtr,IntPtr,Int32,Int32,Int32)(workBuffer ,runBuffer ,row ,column ,width)
public:int SetRowColumnCompressed(IntPtr workBuffer,IntPtr runBuffer,int row,int column,int 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.
