Error "Cannot determine format for"
Hi! I am trying to get transparent background in png pictures, but it is not working and I get error "Cannot determine format for". Only way to get this is by using command line? I am writing something like: save C:\Users\a\Desktop\k [ format png ] [ supersample 4 ] [ transparentBackground true ] or save C:\Users\a\Desktop\k format png supersample 4 transparentBackground true Also, I have tried different variations. Regards, Mikael
Hi Mikael, The first one is definitely wrong because you should not include the square brackets in the command. They are shown in usage descriptions to indicate optional arguments, as explained here: <http://rbvi.ucsf.edu/chimerax/docs/user/commands/usageconventions.html> Make sure the pathname is correct. Maybe you cannot specify the drive in the pathname (the "C:") ... however, I'm on Mac and can't test this directly, but the other developers would know. You could try specifying pathname without drive to see where it goes. On Mac, this works to put a file on the Desktop under my home directory: save ~/Desktop/blah.png super 4 transparent true As in my example, you can just specify format with filename suffix (e.g. "k.png") instead of using the format option, but using the format option like you did should also be OK.

Hi Mikael, Right now, if you don't provide the .png suffix, you have to use a format value of "png image" rather than just "png". Will probably change that to just "png", but right now your command should be: save C:\Users\a\Desktop\k format "png image" supersample 4 transparentBackground true --Eric Eric Pettersen UCSF Computer Graphics Lab

Hi Mikael, If I use menu File / Save... to save a PNG image it logs a command in the Log panel that looks like save C:/Users/goddard/Desktop/test.png width 746 height 466 supersample 3 The transparentBackground option is not in the save dialog but at least this gives you an idea of the format of the command. Most ChimeraX user interface actions log equivalent commands so looking at the Log is a good way to see the command syntax. Tom On 10/8/2020 9:50 AM, Eric Pettersen wrote:

FYI, I added a control for transparent background to the Save dialog for the relevant formats (PNG, TIFF). Will be in tomorrow's daily build. --Eric Eric Pettersen UCSF Computer Graphics Lab
