Hello dear Psychopyers,
I am new and need your kind help and knowledge sharing.
I try to make a visual search Exp, by adapting a template provided by @colinquirk (thank you!!) using the Psychopy library (in spyder).
In the code, the stimuli are used from a folder. I have created a line stimulus file and it works fine when vertical, but not when presented tilted (not vertical), as intended. The following problem arises: the line is jagged and the pixels are messed up.
Is there a way to avoid this ? e.g. by using specialized software for high-quality stimuli ? I tried some changes in size (400x400, 32x226) adapting also the stim_size = (0.25,1) to get it to work, while I tried also the code with the author’s original stimulus (450x450, with stim_size =1) and still got jagged lines.
Any suggestion ?
Dear @colinquirk how did you make the stimuli and what would you suggest ?
Thank you very much in advance
