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. bytes required = lines * ((Width + 3) * 2). Pass a null reference to runBuffer if you do not want to use a work buffer.
runBuffer
The output buffer, which will be filled with 1-bit compressed image data.
runBufferOffset
Offset into runBuffer where the copy operation should start.
row
The number of the row to retrieve. The first row is 0, and the last row is 1 less than the image height.
lines
Number of rows to retrieve.
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.
