bed files minimum track height thresholded at 40 pixels #810

Open malcook opened 4 years ago

In my hands, display of .bed files disallows setting the track height below 40 either interactively or using, e.g., maxHeightPixels=15:15:15 in the trackline.

Yes there are minimum heights for each track type that should be documented somewhere.

malcook commented 4 years ago

ok - but I can't find such documentation. The only mention of max/min heights I can find is:

Select Tracks>Fit to Window. IGV displays all tracks. If necessary, it sets the track height to 1 pixel and scrolls the data.

Regardless... can you consider dialing down the minimum to 10 or 15 across-the board. I use 15 often to good effect on other track types and would like the option for .bed files as well.

Yes but its not as simple as just changing a constant. The Bed track renders features at a constant height and needs 40 pixels for feature + name. So the rendering needs changed to adjust to height to support 10 or 15.
