Hi there!
It's not as easy as it looks.
As far as I know, in each Enigma, the LED picons belong to a different directory. Even each SKIN can use a different directory location. This means that it will necessarily add an extra menu to select a special folder with picons for the display.
It will also be necessary to add another algorithm for downloading different picons - especially for LED display only. Of course, it is also necessary to create an LED list of filtered picon lists (my internal list of all available picons for certain resolution + background + selected satellites), starting with all Chocholek picons.
This means that it would be better to create a new plugin just for the purpose of adding a picon for the front LED display.
A solution could be, for example, converting the resolution of PNG files to a smaller resolution directly using the Python module (directly in the plugin code algorithm). However, this is the copyright of Chocholosuek picons (editing the author's work - editing the images). Also, in this case, there may be a problem with the wrong aspect ratio (not every display template always uses the same resolution for the picons, so I would have to rattle it too).
LED display on the front panel of various set-top boxes is therefore a little more complicated problem and require a complex solution. I would have to take a long time to look at all displays and how to use them, and then I could modify the plugin and add more options for LED display picons.
In my opinion, this is the fault of SKIN developers ! They are lazy! In the Python code, it is very easy to add another Component to the Enigma ("Converter" or "Renderer") so that all standard picons can also be used for LED displays after they are automatically converted to the desired resolution! Any aspect ratio can also be solved by the SKIN code algorithm! For this purpose, the basic module "PIL" is quite sufficient and there is generally no need for an extended module "Pillow" (this is only found in new versions of Python-language or if it is installed additionally).
