The automatic line breaking doesn't make very good use of the space it has available to it, often leaving lines with lots of empty space.

I would suggest letting us use a line break character (ie %13) that disables the automatic line breaking

As well as letting us set the font size to 0, and having it automatically select the biggest font size that will fit all text on screen
For when line breaks are used, it'd have to calculate that font size for each line, then pick the smallest one of them

Would it be possible to add support for this device to the web app?

I'd like to make GIFs that hold on the last frame (by setting it's time to a large number) rather than have to make multiple copies of the last frame, since at current you only honor the frame time of the second frame

When the user uploads, they should be taken back to the same tab they started from after the upload has finished.

Currently when the hardware is disconnected, you echo that error over and over until it's reconnected. But this causes a problem where the queue of error messages can go on for so long that it bogs down the window and I've had to close it and reopen it to get a response again

Instead, I suggest only echoing once on disconnection, then again when it reconnects.

The console logs that the system is looking for console\system.png or .gif but the code requires it to be consoles/default-system.(png|gif)

Looking for: /userdata/system/pixelcade/console\lightgun.png or .gif

Additionally, you should be using the os-specific filesystem separator and not hardcoded strings which are not correct on linux

I'd like to know how long it'll take for the text to scroll all the way off screen, so I know how long to wait for the next command so it doesn't interrupt the scrolling

Looks like a copy/paste issue ("p" instead of "w".) The fix is in line 73 of
PIXEL/pixel-web-enabled/src/main/java/org/onebeartoe/web/enabled/pixel/CliPixel.java

Incorrect:
WebPortOption = Integer.parseInt(cmd.getOptionValue("p"));

Fix:
WebPortOption = Integer.parseInt(cmd.getOptionValue("w"));

Am testing on the Raspberry Pi. The newly updated GIF does show up correctly in the animations pane but when clicking it, this error message occurs:

I've been unplugging my unit when I shut down my PC for the night.
I'd rather send a command similar to the blank-screen command, that stays until it gets the next command.

In some situations, I send text commands every second and that flash is very distracting.

It's not present during GIF animations, so I suspect it can be removed

Minor issue, work around is just use the Chrome browser and don't use Safari for web enabled PIXEL

The webserver makes buttons with ONCLICK="functionname('filename')", but when filename contains apostrophes or double quotes, it breaks the javascript. These need to be escaped, or replaced in the same way you replace spaces with %20

I have been using it for real time applications, specifically a clock, and showing text messages
text messages are set to show in 4 lines
the clock in 2

I sent the text message to the display, and before it was finished scrolling, the clock event fired, and now it's stuck in 4 line mine even though the clock event is sending 2 lines

arcade handler received: /arcade/stream/user/clock?l=0
STREAM MODE
Console Before Mapping: user
Console Mapped: user
Game Name Only: clock

of Times to Loop: null

Looking for PNG: C:\BitPixel\Pixelcade\user\clock.png
Looking for GIF: C:\BitPixel\Pixelcade\user\clock.gif
Found GIF: C:\BitPixel\Pixelcade\user\clock.gif
This GIF was already decoded

This image is generated every minute, and I've deleted it just to be safe. Closed/restarted pixelweb. Same result

I would suggest when ?l=0 is specified, it uploads it anyway

Work around is to stop and re-start the .jar on the Pi. Maybe check that after writing (saving), we are still putting pixel back into interactive mode and not stuck on local playback

The original file size of the PNG on my Mac was 166 bytes and the file size on the Pi was 167 bytes. This file does display fine in the still images pane. When uploading the file, the browser shows this message but it does not go away

I believe this to be a typo? should be pixelcade.org
