Does anyone know how to easily generate pattern code based off an image? Assuming that if you had a pattern image 1pixel wide x “total number LEDs in your strip” that there would be some tool that could read the pixel hsv or rgb values and create the code to load into a new PixelBlaze Pattern. I’ve seen some editors that do this, but they are tied specifically to other led hardware platforms.
I’m afraid of the answer, but I thought it would be worth asking anyway. -Thanks
I’m not aware of anything but it shouldn’t be too difficult to code. I’ve used PHP extensively and it has built-in image manipulation so it would be possible to read in a .gif file (for example), look at each pixel and then output some code. I may well have a bash over the weekend. Do you have any example files?
wow, that’s amazing! The sample file here is a PNG, but I could easily live with GIF if the system doesn’t read PNGs. The included file is actually oversized at 200px tall, but my strip is only 123 LEDs. However, I’d just assume that when a pattern image is created, that the maker will crop it to match the number of vertical pixels to the number of LEDs in their strip (since it’s going to vary for different hardware setups) Feel free to crop it however you need in order to test.
Thank you for your input.
Hi Troy. I’ve actually started but will need to come back later to finish it off - other things getting in the way at the moment! Will drop some code here when I’ve sorted it out! I’m not sure why I mentioned GIF - PNG is much more preferable and it’s already reading a PNG file I knocked up!
Totally understand, I’m just appreciative for the help, regardless of when it happens!
Thanks
You could try this (I’ve not fully checked it but hopefully it works):

If it works OK then I’ll explain what I did!
@zeb,
Cool, stoked that you are helping out with a converter! BTW PB’s variables and constants are limited to ±32,767, as they are 16.16 fixed point numbers. If you want to stuff 3 bytes into a value, you need to divide by 256 to get your constants. e.g. 1658.703125 instead of 424628. Now your red and green are 8 less shifts, and your blue is 8 shifts left.
Aha, that makes sense now. I remember seeing that in Jeff’s code for the scrolling text and wasn’t entirely sure why it was like that! Here’s another attempt at the code (if it doesn’t work then my excuse is that I don’t have a PixelBlaze with me at the moment to test it on!):

If these do the trick then I’ll see if I can get the code beaten into shape!
I’ve been out camping. Will try as soon as I have access. Thanks
No problem. Hope you had a great trip!
that worked great. Even got my momentary switch working. getting close to making this a nice light painting stick! What does the process look like to go from the image to outputting the code?
Excellent! 
I’ll see what I can do to beat the code into shape. Would you be interested if I stood up a web server where you could just upload the image and get the code in return? Or maybe even a .epe file if I can work that out?
that would be great. Thanks
@zeb did you ever polish this code? Just came cross this thread and mentioned it as a solution for POV image uploading
Apologies. I didn’t get anywhere with this. Consider it moved further up the “pile”. I will make some time to get this sorted out. It shouldn’t take too long to get it in a fit state to be usable even if not particularly pretty!
Friendly bump! I know how life goes, but I just stumbled upon this thread and figured I’d see if there was a chance anything had moved forward here!
Just a heads up… I’m about 3/4 of the way through a complete Pixelblaze control library for Processing/Java. Since Processing can read all these file formats and already has image processing libraries that can do selection and scaling, it ought to make this sort of thing relatively easy.
I’ll make a note to include a bitmap → pattern converter of some sort in the examples.
