An instance of class PILDriver is essentially a software stack machine (Polish-notation interpreter) for sequencing PIL image transformations. The state of the instance is the interpreter stack. The only method one will normally invoke after initialization is the `execute' method. This takes an argument list of tokens, pushes them onto the instance's stack, and then tries to clear the stack by successive evaluation of PILdriver operators. Any part of the stack not cleaned off persists and is part of the evaluation context for the next call of the execute method. PILDriver doesn't catch any exceptions, on the theory that these are actually diagnostic information that should be interpreted by the calling code. When called as a script, the command-line arguments are passed to a PILDriver instance. If there are no command-line arguments, the module runs an interactive interpreter, each line of which is split into space-separated tokens and passed to the execute method. In the method descriptions below, a first line beginning with the string `usage:' means this method can be invoked with the token that follows it. Following <>-enclosed arguments describe how the method interprets the entries on the stack. Each argument specification begins with a type specification: either `int', `float', `string', or `image'. All operations consume their arguments off the stack (use `dup' to keep copies around). Use `verbose 1' to see the stack state displayed before each operation. Usage examples: `show crop 0 0 200 300 open test.png' loads test.png, crops out a portion of its upper-left-hand corner and displays the cropped portion. `save rotated.png rotate 30 open test.tiff' loads test.tiff, rotates it 30 degrees, and saves the result as rotated.png (in PNG format). iÿÿÿÿ(tprint_function(tImaget PILDrivercBs eZdZd„ZgZd„Zd„Zd„Zd„Zd„Z d„Z d„Z d „Z d „Z d „Zd „Zd „Zd„Zd„Zd„Zd„Zd„Zd„Zd„Zd„Zd„Zd„Zd„Zd„Zd„Zd„Zd„Zd„Z d„Z!d„Z"d „Z#d!„Z$d"„Z%d#„Z&d$„Z'd%„Z(d&„Z)d'„Z*d(„Z+d)„Z,d*„Z-d+„Z.d,„Z/RS(-icCst|jƒƒ|_dS(sPusage: verbose Set verbosity flag from top of stack.
