Hi,
I need to use a 2-d ploting widget for my image processing app... preferably, this widget should take a matrix input, and should take as little time as possible for displaying itself... any suggestions?:confused:

For my understanding, a 2x2-Matrix is a transformation. What type of data do you want to transform? If you want to plot data, you might want to have a look at QWT.
I you are using qt4 look at examples/itemviews/pixelator, maybe is what you're looking for...
Hi
I am trying to plot the frequency components of a grayscale image... i also need to know if any fourier transform (FFT) libraries are available.Quote:

I am using Qt4... i have already considered qwt.. I havent tried Qwt yet, but the qwt 5 release is unstable, i hear... i also dont know how to install it and use the qwt classes.Quote:

i wonder why you don't try to use ImageMagick and basic QCanvas... it might also help a lot
I just started using fftw and its great, specially since you can use it both under linux and windows.Quote:

Note, that under windows I got bad results when compiling whit VS6.
Dev-C++ solved the problem, and fftw comes as a module in its database.
Hey...
Thanks for the fftw thing.... it seems to be what i'm looking for. Also, i'm working in linux, so i dont think i'll have the windows problem u stated.
