FoamyGuy / Blinka_Displayio_PyGameDisplay

Blinka makes her debut on the big screen! With this library you can use CircuitPython displayio code on PC and Raspberry Pi to output to a PyGame window instead of a hardware display connected to I2C or SPI. This makes it easy to to use displayio elements on HDMI and other large format screens.

Some examples don't run on Raspberry Pi #2

The above examples all fail to run on Raspberry Pi 4 with File is not a Windows BMP file

Reading the pygame documentation it seems that GIF, JPG & PNG are only supported if pygame.image.get_extended() is not False.

I don't know what determines if it is extended or not. As far as I can tell I have the appropriate SDL installed:

> apt list | grep installed | grep -i sdl

libsdl-image1.2/stable,now 1.2.12-10+deb10u1 armhf [installed,automatic]
libsdl-mixer1.2/stable,now 1.2.12-15 armhf [installed,automatic]

libsdl1.2debian/testing,now 1.2.15+dfsg2-4+rpt2 armhf [installed,automatic]
libsdl2-2.0-0/testing,now 2.0.9+dfsg1-1+rpt1 armhf [installed,automatic]

Weirdly, I'm convinced that these have run on my Raspberry Pi before
