Author: Adam Rofer --see readme file for contact information Description: A couple of Picture datatype hacks to illustrate the structure of the (LV 6.1 - LV 7+ is untested) picture control. -- Main VIs -- Example - Show How Picture Is Made.vi: Main example, shows (incrementally) how a specific picture is generated by displaying the picture with each packet incrementally added. Good way to see how your own pictures display information. Opcodes.csv: Comma-delimited file explicitly describing the packet types and their requirements / uses. Tool - Picture concat.vi: Given two pictures, concatenates the data to create a single overlapped picture. Tool - Packets to Picture.vi: Given an array of picture packets (cluster), generates a picture. Tool - Picture to Packets.vi: Given a picture, generates an array of picture packets. -- Utility subVIs -- sub - 8-Bit string to 32-Bit number.vi: utility VI to cast a string to a 32-bit number. Typecast might work instead but this is more explicit. sub - Find Opcode: Given a picture data string that has the size header removed, this will extract an opcode from the front. sub - Strip top of and check picture.vi: Utility VI to strip the header (size) from a picture data string so that it can be scanned for packets. Change Log: 1.0.1: (11/13/06) Cleaned up code for LAVA requirements: - Renamed VIs for clarification of purpose - Fixed coercion dots - Added 0ms delays in all loops - Added error encapsulation in some subvis - Replaced local variable for cluster to constant in order to limit thread swapping between the user interface and code threads 1.0.0: (11/07/06) Cleaned up code from 6i 2001 version for submission.
