Hello,
is there any function in Igor how can I blur pixels (squares) in the Image plot. Similar like in attached screenshot (there is it made by another program).
Thanks in advance,
Petr
Check out the ImageFilter command with the avg algorithm. There are other algorithms available, too.

We have had this request in the past but I have alway been reluctant to do it because I feel it presents a distorted and misleading view when used for scientific data.

However, just recently I have given in and the next beta of 6.2 will support a new ModifyImage keyword:

Added new but undocumented keyword to ModifyImage; interpolate= 1
Turns on smoothing of the boundaries between pixels.
Since this is implemented via the system graphics calls and not by Igor actually doing the interpolation, it will not affect PDF, EPS or EMF export on Windows and will not affect EPS export on Mac.
