The patternpaint's discuss from blinkinlabs

Download animation from BlinkyTape

We can read memory back from the BlinkyTape, so it would be a nice trick to download an animation from a BlinkyTape for further editing.

save to tape button is ugly

On both OS X and Windows, prolly on Linux too. Should redesign this menu so it's not an issue.

Add buttons for load/save to file on the main window

They are hard to find in the menu. In fact, make all the standard stuff available without going to the menu.

Brightness adjustment after uploading

The patternplayer sketch should implement the brightness adjustment feature from ColorSwirl.

Window doesn't resize when opening new animation

When an animation is opened that is larger than can be shown in the current window, it remains hidden until the user makes the window longer

Platform: OS X (but should affect all)

Steps to reproduce:
-Open a long animation

Allow arbitrary screen resizing

This ends up looking ugly up close in some cases, but is still desirable:

Detect device disconnect in Windows

QT serial doesn't seem to send a notification that the pipe has been broken in Windows; maybe we need to scan for this ourselves?

Steps to duplicate:

Run PatternPaint on Windows 7
Connect to tape
Unplug tape

Expected behavior: BlinkyTape.c gets notification that the device is gone, disconnects
Observed behavior: BlinkyTape not given any warning, continues running as if the device did not disappear

Sample animations

Should include some sample animations, to give inspiration on how to make cool patterns.

Image compression

Should at a minimum support compression to RGB565 and RLE, in order to increase maximum image length.

Save to .h file

For advanced Arduino users, it would be nice to have a way to export .h files from PatternPaint, so they can be used in non-standard ways.

Text tool for lightpainting

A quick wizard to generate a new animation from a string of text would make light painting words fun.

Unable to build on Linux

Having trouble building on Ubuntu: can't get the QtSerialPort library to get picked up.

Downloaded the library, did a command line install (as root). Still getting

QTSerialPort: no such file or directory

in blinkytape.h.

Where do I go to get instructions on setting up a build environment for QT4 with the proper prerequisites?

About window is ugly

Should either replace with a splash screen (not really useful) or merge with system information dialog.

Program icon missing in OS X 10.6

It appears to be fine in 10.8 and 10.9. Not sure about 10.7 either.

Drawing over frame indicator results in hang!

Open PatternPaint and connect. While the frame indicator is moving, mouse & draw over it. After a few moments the BlinkyTape will hang. Remove USB connection and use connect/disconnect button to reconnect.

Maybe updating too fast?

Feedback when uploads fail

Currently, when a tape is unexpectedly disconnected, the uploader fails, etc, there is no feedback to the user. Add some sort of mechanism (desktop notification?) that the operation failed, so the user can respond to it.

Poll for bootloader device inserted

On slow systems running windows, it seems that it can take >4 seconds for the bootloader device to become available. That makes the one-shot method currently in use unreliable. This should be switched to a polled method that continually scans for new devices for up to N seconds (maybe 8 + 2) before giving up.

Clear animation feature

Right now, the only way to start a new animation is to draw over it with a black tool, which is kind of poor. A clear button or menu item could be useful.

Only upload arduino sketch if necessicary

To mitigate the potential for blinkytape bricking, patternpaint should only upload the sketch portion if it has actually changed.

Connects to BlinkyTape but doesn't show any updates

If the program is opened, connected to a BlinkyTape, then closed, sometimes a subsequent open will connect to a BlinkyTape but the BlinkyTape will not show animation frames.

This seems to be a problem with the Arduino sketch. Workaround is to unplug BlinkyTape from USB and then reinsert.

Window resize is ugly

When the main window is resized, the interface is centered in the larger window, and the animation portion doesn't change size. What should happen here? Perhaps the window should not be resizaable?

Ghost pixels / inaccurate rendering

When sending a small number of bright pixels from one end of strip to the other (draw diagonal line in PatternPaint box) lower-number pixels turn on at maybe 30% intensity following that one. Gamma / antialising error?

Crashes when the tool size is too small in release version

Steps to reproduce:

Run release version on OS X
Drag tool size slider to the right and then all the way left
Click in the pattern window

Better paint tools

The current paint tool is basic and sort of obnoxious. Nicer ones such as a line tool, stamp, gradients, etc, would be great additions.

Undo/Redo in editor

Should be possible to brute force at least, QT has QUndoStack that could work.

Windows deployment instructions

Need written instructions for how to do this, followed with a script.

More informative labels would make the program easier to understand

save-> 'save to png'
upload->'upload to tape'

Opening JPGs on windows fails?

This was reported, need to check and fix if it's true.

QT libs location misleading

The QT library location shown in the system diagnostics page appears to be set at compile time, so it doesn't provide relevant information to the user. It should be removed.

Make height configurable

Hi,

I am experimenting with PatternPaint on linux for another project using a 30 LEDs/meter strip. (BTW the code compiles fine with qmake -qt=5 && make from command line, only some warnings).

I hacked the code to generate animation for HEIGHT 30, here is a rough patch in case anyone wants to use it:

Add timer that periodically scans for and connects to a blinkytape if one isn't being connected to

It can be a preferences option, autoconnect

LOAD THE FRIGGING RAINBOW

An option to load the color swirl factory app back on to the tape, to have something pretty.

Upload stuck at 0%

Sometimes an upload will get stuck at 0%. This is a timing issue caused by the BlinkyTape not resetting in time; it should be fixed in PatternPaint by allowing PatternPaint to search for a new device for multiple seconds rather than once. Workaround is to disconnect from BlinkyTape in PatternPaint, uplug BlinkyTape from USB, then reinsert. Sometimes PatternPaint also needs to be restarted.

A specific .jpg file won't open in OS X

Attempting to open this file doesn't work in OS X. Unsure if other platforms are affected.

PatternPaint version: Release 0.2.0
System affected: OX X 10.9
Steps to reproduce: File->Load File, select image

Expected response: Animation is loaded in PatternPaint
Observed response: File isn't loaded, and no prompt is returned to the user. Running in debug mode give the following message:
debug MainWindow::on_actionLoad_File_triggered: Error loading animation file "/Users/mattmets/Desktop/testImages/ingtekL.jpg"

Remember animation load/save locations, give sane defaults?

When animation open or close are selected, they default to some unhelpful directory. They should default to somewhere sane (platform image/media directory?), and remember their last location for at least the duration of the program running.

Platforms affected: Windows, OS X, Linux

Turning speed up while connecting to BlinkyTape causes the BlinkyTape to become nonresponsive

Either limit the maximum speed or ???

Improve RLE compression for animations with many single colors

By lowering the color space to RGB555, the first bit could be used as a flag to say whether it is a single color, or a run of colors- that way the worst case would be as good as an RGB565 image with random data, and the best case would be as good as RGB565+RLE:

single case: 0RRRRRGG GGGBBBBB
run case: 1xxxxxxx 0RRRRRGG GGGBBBBB

where RRRRR, GGGGG, BBBBB are 5-bit color encodings, and xxxxxxx is the run length.

Scroll bar for long animations

Opening a long animation causes it to go off-screen, without indicating to the user that the window should be resized. A scroll bar should be added to allow the user to scroll along the animation, and to indicate that there is more to see.

Light painting mode

As suggested by teaelixer on the forums:
http://forums.blinkinlabs.com/index.php?p=/discussion/120/blinky-tape-with-8-bit-graphics

I am happy to be able to make these pictures, but it would be "cherry on top" if there was a timer display or how long the animation will take and a hotkey starter button (any dedicated key on the keyboard) that will start/end the animation. Holding down the button will allow it to loop animation until release.

Lastly, I would love to take this to the next level with making a series of pictures into an animation. At the moment I haven't found an efficient way to paint yet...

add link to troubleshooting pages/etc

Should have links in the help menu to pages on the website:
http://blinkinlabs.com/blinkytape/docs/troubleshooting/

Drag/drop support for pictures

Would be great to be able to drag a photo file from the file manager directly into the program, instead of having to navigate to it using file open.

Unplugging a BlinkyTape while connected can cause the program to hang

To reproduce:
-Run PatternPaint, plug in a BlinkyTape, click 'connect', then unplug the strip

Usually, this will cause the app to crash.

Flip/Mirror image for lightpainting, etc

App Nap on OS X 10.9 suspends PatternPaint

When running PatternPaint in the background on a machine running 10.9, the pattern eventually stops updating, and the BT reverts to playing it's built-in pattern. This appears to be related to PatternPaint being suspended. Likewise, when a really long pattern is played and the screen is not updated, a similar behavior seems to happen.

PatternPaint version: 0.2.0
Operating system: OS X 10.9
Steps to reproduce: Load long pattern, connect to tape, minimize PatternPaint
Observed behavior: described above
Expected behavior: pattern runs continuously

Run PatternPaint on Windows (any version?
Select 'save animation'
Type in a file name without extension
