Leadtools Namespace > RasterImage Class > SetRowCompressed Method : SetRowCompressed(Byte[],UInt16[],Int32,Int32,Int32) Method



workBuffer
Optional work 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 a null reference (Nothing in Visual Basic) to runBuffer if you do not want to use a work buffer.
runBuffer
Input buffer, which contains 1-bit compressed image data.
runBufferOffset
Offset into runBuffer where the set operation shoule start.
row
Number of the first row to update.
lines
Number of rows to update.
Puts one or more rows of 1-bit compressed data from a buffer into an image that is maintained in its compressed format.

Parameters

workBuffer
Optional work 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 a null reference (Nothing in Visual Basic) to runBuffer if you do not want to use a work buffer.
runBuffer

runBufferOffset
Offset into runBuffer where the set operation shoule start.
row
Number of the first row to update.
lines
Number of rows to update.

Example

For an example, refer to GetRowCompressed.

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.

For more information, refer to Speeding Up 1-Bit Documents.

Requirements

Target Platforms: Microsoft .NET Framework 3.0, Windows XP, Windows Server 2003 family, Windows Server 2008 family
