[vtkusers] Code for graphics file read/modify/write. Warp. Images to 3-d.

[Robert Caldwell]

Dear Group,
      I was using PAINTLIB for manipulating bitmap graphic files (and the 
2-d data they represent) alongside VTK, but decided to remove PAINTLIB and 
use VTK throughout. I'm not yet up to speed on the details of VTK's classes 
so I would appreciate your sending me (mailto:rcaldwell1 at unl.edu) code 
examples for how to:

         -- Read standard graphics files: PNG, JPEG, TIFF, BMP 
(vtkImageReader2Factory?).
         -- Get the array of pixel information, for analysis and 
modification (vtkImageCanvasSource2DPixel?).
         -- Place the modified pixel information back into the object.
         -- Write the updated information in a user-selected graphics file 
format.

     I also need to become familiar with classes and functions for warping 
images, e.g., calibrating and removing camera lens distortion (vtkCamera? 
vtkWarpLens? vtkGridTransform?), and I would like to evaluate methods for 
extracting 3-d representations from a series of pictures taken from 
different view directions (??). Code for these things -- especially in C++ 
-- would be very helpful.
