<div dir="ltr">Hi all,<div><br></div><div>Interesting little problem when trying to read colors assigned to attributes. A Nx4 array of colors can be assigned but not properly subscripted. Given the code below:</div><div><br></div><div>ares = True</div><div>ares@cnLineColors = read_colormap_file("BlRe")</div><div><br></div><div>I then tried three different operations.</div><div>1) print(ares@cnLineColors) ----> results in full Nx4 array output on screen.</div><div>2) print(ares@cnLineColors(0:10,:) ----> Warning that attributes are only one dimension (not a true statement), no output</div><div>3) print(ares@cnLineColors(0:10) -----> Segfault, no warning received, in contrast to most other attempts to read with wrong number of subscripts.</div><div><br></div><div>Warning is received as expected if indices exceed dimensions, regardless of dimensions included/referenced in the subscripts.</div><div><br></div><div>Seems like this may have been overlooked at some point. Further, is support for any 2+ dimensioned attributes an intended feature?</div><div><br></div><div>Full output for cases 1-3 below.</div><div><br></div><div><br></div><div>Kyle</div><div><br></div><div>
