Hello,

Thanks,

You can get it to scale with these steps:

1. Make your own copy of the file at /opt/octoprint-tft/styles/default/style.css. Edit it to modify the styling. I updated font sizes so they look decent on the 7" Pi screen. See the code fragment below for the lines I inserted at the top of the file:
2. Note the full path of your edited style.css. Into the same directory, copy over the images/ directory (recursively with all its contents) from /opt/octoprint-tft/styles/default/.
3. Open /etc/octoprint-tft-environment and set the variable OCTOPRINT_TFT_STYLE_PATH to the path (just the full path to the directory in which your style.css and images/ sit). You may need to do this with sudo so you have write permission on the file.
4. Reboot the pi.

button {
    font: 24px Sans;
}

label {
    font: 18px Sans;
}

progressbar {
    font: 18px Sans;
    padding: 10px;
}

There is a problem in the main() function with the variables, height & width. Golang is a "pass-by-value" language. The 'getSize()' function will not alter the inherent value of the variables 'height & width' as written. Because of the scope of those variables, any changes accomplished in 'getSize()' are lost when go returns to main().

The fix for this problem is to declare 'height & width' like this:
var (
BaseURL string
APIKey string
ConfigFile string
Resolution string
height int
width int
)
or
use pointers
