Public Method write1D2DRunLengthEncodedScanLine

static void write1D2DRunLengthEncodedScanLine(int prevLineOffset, int noOfPixels, int noOfRleBytes, byte[] data)

Throws:

• ILCDException

_INSERT_METHOD_SIGNATURE_HERE_

Parameter	Range	Description
prevLineOffset	-8 ... 8	y-offset of scanline referred to (0 = none = 1D encoded)
noOfPixels	1 ... display width	number of pixels to write
noOfRleBytes	2 ... display width + 2	length of encoded data in bytes
data	0x00 ... 0xFF	array storing run length encoded data

Writes a horizontal scan line consisting of noOfPixels pixels onto the screen. The noOfRleBytes long data is sent with run-length encoding.

• The location where the pixels are written to (where the horizontal line begins) is determined by the current cursor position.
• The column address is incremented after every pixel. Even so, the scan line is drawn correctly until it hits the screen margin.
• When prevLineOffset is 0 or prevLineOffset + the current row is negative, only 1D encoded data will be accepted.
• When prevLineOffset is other than 0 and prevLineOffset + the current row is 0 or higher, the data can include sequences for 2D encoding with reference to the relatively specified row.
• Color values in the reported data are made up as 16-Bit Color Values.
• For detailed information about the encoding algorithm and its usage, please refer to the 2D Run-Length Encoding Application Note.

Example

byte[] data = new byte[] { (byte) 0xB1 , 0x1F, 0x00 };

Draw.write1D2DRunLengthEncodedScanLine(0, 50, 3, data);

This example will write 50 blue pixels to the screen, starting from the current cursor position. The encoded data consists of 3 bytes: 0xB1 indicates a horizontal repetition (bit 7 set) of 50 pixels and 0x1F00 is the 16-bit color value for pure blue.
