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 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 should start.

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

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.
