C# : Adding Text Annotation + Signature to a PDF Document
Add a text annotation to a PDF using iTextSharp . Then add an esignature field on top of the annotation using the DocuSign Signature Appliance Local API.

The construction of the serial command has the following syntax: "#" + channel (0-31) + "P" + pulsewidth (750-1500milliseconds) + "S" + speed(milliseconds for move) You can string up to 32 commands together before you have to terminate it by appending the following: "T" + time for total move(milliseconds) + "\r" The pulsewidth is the time in milliseconds that I have simplified via the getPw() method. It will return a pulsewidth ranging from 750 to 1500 from a byte between 0 and 255. Finally, the test program uses only two servos and moves them to positions 100 and 200, respectively, during a 1-second timeframe. (See Example 3-12.) Example 3-12.

Summary

public void cmd(int ch, int pos, int spd) throws Exception { // ensure position is valid if (pos < 0 || pos > 255) { throw new Exception("position out of bounds"); } // call createCmd then append to string buffer cmds.append(createCmd(ch, pos, spd)); } // allows for raw command string to be sent public void setRawCommand(String rawCmd) { cmds.append(rawCmd); } // this is the protocol for the command string for the LM32 public static String createCmd(int ch, int pos, int spd) { String out = "#" + ch + "P" + getPw(pos) + "S" + spd; return out; } // sets the LM32 busy for specific milliseconds private void setBusy(long ms) { // the set busy function busy = true; // gets time when it should be done Date timeToRun = new Date(System.currentTimeMillis() + ms); Timer timer = new Timer(); // schedules time to be run so busy can be set to false timer.schedule(new TimerTask() { public void run() { busy = false; } }, timeToRun); } // accessor public boolean isBusy() { return busy; } // static utility method public static int getPw(int pos) { int pulsewidth; double percent = (double) pos / 255; double pwfactor = percent * 1500;
