Yeah, I get the scaling, I meant that I couldn't use the finished large bitmap (768x1480) and then just resize the whole thing (down to 384x740), the compression algorithms for photoshop cause blurring etc that ruin the alpha or the simplest one (called nearest neighbour) causes artifacts. Instead each file has to be constructed individually, but I did do what you suggested and ported each icon over 1 at a time, using a resized bitmap as a template to align them.
As for unit types, that information, is currently not displayed in this mod (other than differentiating cav, inf, art, skirmishers). I'll have a think, perhaps colors, perhaps line thickness, or resorting to letters might work, but space is limited.
Some other things I noticed while testing...
All cavalry use mounted symbols all the time (most can't change formation - so thats fine) i.e. half the cav icons on the sheet are never used - but this is true even for dragoons that can dismount. I added a dragoon line symbol in case it is changed later in the engine but at the moment it isn't used.
Unit facing in the Napoleon games is towards hex corners, in ACW it is towards hex facing. No symbol sets I have seen account for this, including the new default ones and the old ones, and all point at 45 degrees and leave the player to interpret it correctly - which is fine I guess. 45 degrees makes for neat, tidy icons though.
Nearly done with a first version:
Mag:
Large
Small

UPDATE:
Ok, I guess the draft version is done (v1.0), repurposed most icons from ACW series, made a few new icons too. Download and extract to your MAP folder (of course, backup your original files too). Currently the objective flags are for Waterloo, but will work with several others campaigns that feature Prussia, Russia and Austria (I think so anyway, I only have NAP:Waterloo, so I can't test it out thoroughly).
