When I try to run PanelDemo.py I get the following error:

Doing imports, please wait...
PathSetter.py: Parent folder added to sys.path
Traceback (most recent call last):
  File "PanelDemo.py", line 33, in <module>

Any clue? Running PanelCheck.py works just fine.

Hello ,

I am doing some test with your Examples and it's like that the program freeze/stop to run.

The animation is stuck but the Rpi isn't bugged

i have to close and rerun the script to start again the animation

The crash occur every 21min and 17sec (i try many times) on your MixedDemo.py with a 64*64 display

There is no crach on the windows simulator.

Can you reproduce this bug on your system ?

ImageDemos.py keeps crashing with the no module named matplotlib.colors.

I imported matplotlib, and it was successful, but I still get the following error when trying to run ImageDemos.py:

Starting, please wait...
PathSetter.py: Parent folder added to sys.path
Traceback (most recent call last):
  File "ImageDemos.py", line 26, in <module>

Any thoughts?

PS - I forked your project, which is why the path looks different. I'm also running this on a Pi 4.

Hello Brian ,
How are you ?

I am doing some test with differents texts and logos on a 128*128 LED panels

I notice that when there are some fixed text or logo (TextAnimations.On() method for exemple ) ,
the text or logo Flickers

I try to change FPS but no change ..

How i can resolve this problem ?

with scolling text i have not noticed any flickers problems , it's strange ..

I don't remenber but with older versions of your lib i have not seen this problem earlier ..

there is no problem on the windows simulator

can you help me please ?

Hello ,

I really like your library , thank you for your work !

I clone your repo on my local windows 10 dev pc and install pycharm and anaconda2 and i can run perfeclty your differents examples and it works like a charm.

But on my Rpi3 (i am on the same wiring Active3 with 64*64 LEDpanels) with Raspbian jessie with python lib installed from Hzeller , i also installed berryconda for the dependencies.

I have the following error when trying to play your examples :

"Traceback (most recent call last):
File "PanelDemo.py",line 50, in
videoName"./PanelDemo.avi")
File "/home/pi/libtest/LEDAnimator/Panel.py", line 144 , in init
canvas=matrix.CreateFrameBuffer()
AttributeError: 'rgbmatrix.core.RGBMatrix' object has no attribute 'CreateFrameBuffer'
"
it seems that there is no method "CreateFrameBuffer" in the rgbmatrix from hzeler.

i don't know what i have to do to debug this , Can you help me please ?

OpenCV appears to only use Hershey fonts.
Using PIL it is possible to read and render TrueType and OpenType fonts but requires converting the numpy array to a PIL image and back again.

Hello Brian ,

I don't find a way to Stop and restart the Animator

like A.stop() to stop the animator on the panel and after add new Sequence and relaunch it for exemple

Can you help me ?

Hello Brian ,

After several test on the TextDemo.py i don't find a way to scroll a text "entirely" :

the text do not complety exit from the left side of the screen

instead of that it's disappears when the end of the text reaches the right side of the screen
(when the text is larger than the screen itself otherwise it's disappears when the beginning of the text reaches the left side)

it's a bit complicated to explain but the problem makes scrolling not smooth

Hello Brian ,

I try to do a simple Programme animation with only a logo and a 2 texts message.

I want to display my logo on the all screen for 5 seconds , after that i want to play two scrolling text for 8 seconds at the same time and loop again all the sequences (Logo + texts). i want that the text is displayed alone (without any logo)

I try some possibilities to do that (with StartPause and EndPause) but isn't work for me because either the text is over the logo or the logo is over the text and it's not good for me ...

Can you help me please ?

Valentin

When calculating the length of a text message the code calls the relevant method for each font to find out the length of the message in pixels in order to create an image onto which the text is rendered before being sent to the panel.

The code handles multicolored text character by character and uses the individual character widths to place the characters. Unfortunately this results in the string being too long.

To solve the problem Multi-colored text needs to use kerning.

hello brian ,

i have an exception when i play an animation :

Hi Brian,
I am interested in your library but I do not know how to install and run the examples,
I did not find any installation instructions, It's not even clear how the simulator can be run, please correct the instructions.
Also, I wrote an simulator with pygame that has an acceptable speed.
I suggest watching the video below.

Thanks,

Hello Brian,

I have an 1px border now when playing your Examples in both Simulator and Panels.

Can you please remove this like the previous version ?

Thank you ,

This happens because the class TextAnimBase is expecting a Text() object so it creates an empty buffer at 0,0.

Changes are required to the code to make this work as expected. Currently, if you supply a Text() object to the TextAnimation.Wait animation the text will/should appear in the specified location for the duration of the Wait.

Workaround: use ImageAnimations.Wait instead.

Currently the code does not support characters beyond ascii code 255.
Need to find out how to put unicode characters into python 2 strings

Hello Brian ,

I am doing some test with differents scrolling texts on a 256*64 LED panels

I notice that when the panel is bigger than 6464 (like 25664) the scrolling is jerky ..

I try to change FPS but no change ..

How i can resolve this problem ?

on the windows simulator the problem is less visible but it's also a little bit jerky

can you help me please ?
