Hi! This constantly happens when saving screenshot images:

Code: Select all

[Tools >> Screenshot tool@addOnScript:info] Select the camera or vision sensor you wish to generate a high resolution screenshot for. This model is courtesy of Ulrich Schwesinger.

Hello,

can you tell me how to reproduce the error?

What version/revision of CoppeliaSim are you running?

Cheers

Hi,

I can't reproduce the error...

Yesterday I restarted the Coppeliaism for several times, the error still existed. But today after I reboot the computer, the error is gone.

I use the latest v4.9 rev6.

I know why the error occurred. When saving the screenshot, ​​all the text in the "file name" input box is selected by default​​. If you enter a file name without including the image format suffix before saving, it will trigger the following error:
