[Pipmak-Users] File IO with Pipmak and image manipulation.

[Andrea V. <and...@gm...>]

Hi Chris,

I have two questions for you.

The first:
I need to write and to read info from external file, I tried standard Lue IO lib
without success:

  for line in io.lines(filename) do ... end

and

  for line in file:lines() do ... end

How I can do that?


Second one:
It would be difficult implement in pipmak a method to distort a patch in a
perspective manner?
That is, a function which deform a rectangular patch in a
trapezial one,
passing 4 arbitrary points that lie on the surface of a cubic face.

This think would be very usefull,
so I haven't to create with photoshop a lot of different views of the same
patch, but I could generate those with script.

Another useful method would be a function to crop a patch.


Thank you for your answers

Ciao.

Andrea
