Hi, Some more Veusz requests.
(1) Fits Import & WCS. As a follow-up to Christian Ambrose's query on fits file imports, I would find it useful to have a function, either on the import step or later, to reset the WCS header data on 2d datasets, I.e. Set the CRPIX1/2, CRVAL1/2 and CDELT1/2 values to 1. This means that each pixel co-ordinates is just the matrix position. This would obviously be useful mainly for data that has square pixels. (2) Expanding operations to include 2D datasets. As far as I can see, Operations only happen on 1d datasets, is this correct? If so, I would like to be able to expand this to 2D dataset where appropriate. For example, I would like to be able to filter images to mask out low values, setting them to Nan, so they are not plotted. You can do this with Transparent data, but it's a pain. You would probably need a generic value name for the data for the filter function, e.g. '($DATA<10)' (3) Graph Axis Sizes. At the moment, the size of the plotting area is controlled by the page size less the margins, in both directions - this can be a computational pain. It would be good to be able to set the axis lengths absolutely, especially for 2–d plotting of square pixels where the matrix dimensions are not the same. I would presume that the margins would then be recomputed automatically.
