Hello,
Can anyone tell me the algorithm pmview uses when resizing with the resampling option? Best of all would be if someone who knows could describe the entire algorithm and/or send me some code, but it would be extremely useful to know whether it's a simple bilinear resampling scheme, or bicubic, or sinc, or put through a low-pass filter and then something else.
Any info greatfully received -- I'm using pmview in a research project and I ought to include this information in my paper.
Thanks,
Andrew
Hello,
The "Standard" resampling uses a Triangle filter (Bartlett window, 2nd order b-spline)
The "High Quality" resampling uses Mitchell & Netravali's two-param cubic filter (See Mitchell&Netravali, "Reconstruction Filters in Computer Graphics", SIGGRAPH 88).
Thanks,
Peter
The Transform menu always uses the "High Quality" filter, i.e. Mitchell.
