This GIF is not displayed correctly in

[mmouchous-ledger]

By using the Boilerplate/Rust application and changing the file name in ui_menu_main function from

    const FERRIS: NbglGlyph = NbglGlyph::from_include(include_gif!("crab_64x64.gif", NBGL));

to

    const FERRIS: NbglGlyph = NbglGlyph::from_include(include_gif!("qrlink.gif", NBGL));

output is inverted on Speculos and miss-shown on real device (Flex and Stax)

File has been generated with this code:

import qrcode

# Create a QR code object
qr = qrcode.QRCode(version=1, box_size=2, border=0)


# Define the data to be encoded in the QR code
data = "https://www.ledger.com/"

# Add the data to the QR code object
qr.add_data(data)

# Make the QR code
qr.make(fit=True)

# Create an image from the QR code
img = qr.make_image(fill_color="white", back_color="black")

# Save the QR code image
img.save("qrlink.gif", format="GIF")

In this case:

• The inversion of the color is present only on the RUST SDK, so it may be a problem in the "include_gif" macro.
• The distorition of the image is also present for the C SDK, so it may be a underlying problem. Note that it is appearing for images which are not sized with a multiple of "4" (or maybe 8) in height (or maybe width)
