- workBuffer
- Pointer to unmanaged memory 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 IntPtr.Zero to runBuffer if you do not want to use a work buffer.
- runBuffer
- Input buffer, which contains 1-bit compressed image data.
- row
- Number of the first row to update.
- lines
- Number of rows to update.

Parameters
- workBuffer
- Pointer to unmanaged memory 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 IntPtr.Zero to runBuffer if you do not want to use a work buffer.
- runBuffer
- Input buffer, which contains 1-bit compressed image data.
- row
- Number of the first row to update.
- lines
- Number of rows to update.
For an example, refer to GetRowCompressed(IntPtr,IntPtr,Int32,Int32).
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.
