8 years ago The drawtextplugin is for Mac/Linux only. So that is not a (new) error.
The xyL fails for me too. Not sure why. But given that I want to fix some things in the GUI and that calibration doesnt really work yet, I'd like to fix those things first and then come back to this issue...

8 years ago @bartkrekelberg Does the gui work for you currently? I don't need it working yet, but just curious.

7 years ago The gui seems a long shot now doesn't it? Do you think there would be enough time in the frame loop at typical frame rates for doing it? Simply mirroring the subject window should be possible at least, if not the rest.
What are your latest thoughts on this?

7 years ago We have a mirror monitor (the viewpixx has a hardware copy). So the software version mirroring is not a high priority for me.
Also, with the propsToInform it is relatively easy to create updates for the experimenter that are similar to what one would see in a gui. We could improve that (e.g. by calling clc between calls to put the information in the same place on the command window for a cheap gui).
A real gui with frame-level updates is likely to screw up performance…

@bartkrekelberg adamDemo works without the GUI, taking 5-9ms for the frame loop. But things go a little weird with the GUI, in several ways (see below). The frame-loop with the gui is taking around 12ms with an sd of around 2ms - so its perhaps slower if anything. I'm getting a reasonable number of frame drops even at 60Hz.
Issues: It crashes if the color mode is xyl (error copied at bottom).
If I change to RGB (and change all color properties to suitable values (e.g. gui.toleranceColor = [1 1 0]; c.screen.color.text = [1 1 1];), it works, in the sense that the gui is drawn, but the text feed formatting goes a bit awry from from around trial #5 and frame drops occur. Then again, I'm getting this issue also, which may be the cause of the weirdness:
PTB-DEBUG: DrawText: Failed to load external drawtext plugin [Unknown error]. PTB-INFO: DrawText: Failed to load external drawtext plugin 'libptbdrawtext_ftgl64.dll'. Reverting to legacy GDI text renderer. 'help DrawTextPlugin' for troubleshooting.
@bartkrekelberg do you get this msg too? I'll troubleshoot that issue when I get a chance
Running in xyl mode gives this error:
