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 BytesPerLine property. Pass a null reference (Nothing in Visual Basic) 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. Calculate the required size of this buffer as follows: bytes required = (Width + 3) * 2.

runBufferOffset

Index into runBuffer where the get 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.

column

The column offset within the row to retrieve. 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

This method is available in the (Document/Medical only).

This method is useful for working with 1-bit images that are loaded in their compressed formats for faster loading and display.
