Show images on the screen of the EV3

Postby buzz_lightzyear » Wed Mar 23, 2016 12:15 pm

Hello,

I am trying to show the stored picutures on the EV3 Screen itself. I have the official Lego EV3 documentation in front of me and it shows an example, that shows the "mindstorm"-logo on the screen. That works fine so far, the mindstorm logo is in the "UI-Folder" (ui/mindstorms.rgf):

But now i want to show other pictures on the screen like the eyes or something else... can someone tell me the name of the folder or how I can access the folder structure of the Ev3-Brick? The "xxxxxxxxx" folder includes nothing ;-)

Thx & Goodbye,

Firstly please do not post questions like this in the Development section of the forum. That section is intended for discussions about developing leJOS itself, not about using leJOS. I have moved your post to a more appropriate place.

Secondly what software are you actually using? leJOS dos not use .rgf files, nor does it have the structure that you have included with your post. Perhaps you could post the leJOS/Java code that you have been using to display an image?
