Parameters

row

The number of the row to update. The first row is 0, and the last row is 1 less than the image height.

buffer

Buffer containing the image data. The data is copied exactly as it is stored in the buffer. The buffer should contain uncompressed data regardless of whether the image is compressed or not.

bufferIndex

The zero-based index into the buffer where the set operation should start.

bufferCount

Number of bytes to set. Use the BytesPerLine property of thiss RasterImage to determine the byte count of each line.

Return Value

The image memory must be locked when you use this method. Normally, you can call Access to lock the memory before starting an operation that uses this method, then call Release when the operation is finished.

You can use the BitsPerPixel property of the image to determine the number of bytes to set the bufferCount parameter. If the image is 8-bit then each byte is an index to the palette. If the image is a 24-bit image, then each three bytes represents one pixel element. Color order is determined by the Order property of the RasterImage object. This value can be RasterByteOrder.Rgb, RasterByteOrder.Bgr, or RasterByteOrder.Romm.

RasterByteOrder.Gray is only valid for 12 and 16-bit grayscale images. Support for 12 and 16-bit grayscale images is only available in the Document/Medical Imaging editions.
