PixelAccessorAcquirePreviousScanline Method

Acquires the previous scanline in the image.

Namespace:  Atalasoft.Imaging.Memory
Assembly:  Atalasoft.dotImage (in Atalasoft.dotImage.dll) Version: (.NET 4.5.2, x86)
public byte[] AcquirePreviousScanline()

Return Value

Type: Byte
Returns an array of bytes or null if the previous scanline would be outside the image's bounds.
For the sake of efficiency many implementations of PixelAccessor may return the same byte array, but with different contents. If you need to keep the data from a previously acquired scanline, you should use multiple PixelAccessor objects or explicitly copy the data in the array.
