How are images to be loaded onto the Badger2040w? #27

Closed KnownBySomeone closed 1 year ago

KnownBySomeone commented 1 year ago

I have not yet figured out how to load image files onto the Badger2040w and get them to display.

Steps I have taken: -I read the readme within /examples/image.py """"Images must be 296x128 pixel JPEGs Create a new "images" directory via Thonny, and upload your .jpg files there."""

-I created what I believe to be a 1bit, 296x128 pixel .jpg image file. The same file as attached.

-I loaded said file into the /images folder alongside the /images/badgerpunk.jpg file, and got the message, "JPEG: could not read file/buffer. JPEG: could not read file/buffer."

-I have also loaded the image in other locations that did not follow the readme, but have had no success as well.

-I have also separately tried changing which extra data is saved and tried saving the image as grayscale when extracting the image from GIMP.

What's the code you're using to attempt to load the image?

Does a regular open("/images/filename.jpg") work?

As instructed in the readme, and as I am used to using with MicroPython, I loaded the image file using the graphical interface included in Thonny.

What's the code you're using to attempt to load the image?

Does a regular open("/images/filename.jpg") work?

That open line is Python code. For example: open("/images/badgerpunk.jpg") should work in your current setup.

After uploading the file, so should open("/images/CatTree01.jpg") and using the JPEG decoder: jpeg.open_file("/images/CatTree01.jpg")

I hope to get back to this, if possible later today, but in the mean time...

This is the file that, from what I understand, should open and display .jpg images from the said images folder without me telling it through code what to open. https://github.com/pimoroni/pimoroni-pico/blob/main/micropython/examples/badger2040w/examples/image.py

I recreated the steps I took in this video.

If you're still having trouble - it might be worth checking that you're saving your .jpgs as non progressive? The image you posted above didn't work for me, but this one (opened in GIMP and exported without the progressive flag ticked) seems to work OK:
