Glad it wasn't just me. I threw together a board of a bunch of Donner Pedals, sorted by input dimensions.

Donner mis-match

If you look at the two on the left (or the two on the right), they have exactly the same size, are cropped well, but wildly different sizes.

Seems to be a bigger issue than just getting the pedal dimensions right or cropping.

Sometimes the machines rebel and the automatism does not work. So see the note from further up:

So if the autocrop does not work uploaded PNGs that were edited with an external software indeed give the best results.

I have reworked the pictures, your pedalboard looks good now.


Here's an example from me :

(sorry must have deleted the old one)

The model feT on the left was my old (and now unnecessary) attempt at adding the pedal, with the 93 x 116 mm dimensions of the Hammond 1590BB. Next to it is a pedal with a 118mm height that's clearly completely different, and next to that is someone else's attempt at a model feT, with 148mm height that's still not as tall as the 118mm of the Sea Machine in the middle.

The Model feT image was a PNG, with a surrounding transparent surface.
See note from further up:

if you upload a PNG there is no auto image processing involved.
So if the autocrop does not work uploaded PNGs that were edited with an external software indeed give the best results.

I have corrected all pictures of your pedals. Everything should fit now.
