[Mathrim]

there is the Folder with the new .png and the generated .KiCAD_mod files.

[Mathrim]

can anyone with cicad v.5 import the Modfile to tell me if it works

[pedro]

The footprint is empty.
Open it with a text editor and see that there is no information about any line of the logo.

I’m sorry I can’t create the footprint either.

[Rene_Poschl]

If you have your picture as a vector graphic then you can try and use svg2shenzen.
More details see: Using Inkscape plus Svg2Shenzen to create complex footprints

[Mathrim]

Found the reason for the problem!

Kicad says black lines are transparent and Transparent spaces are also transparent.

So my .png was convertet from black on transparent to transparent on transparent and thats the reason for the empty modfile.

So your .png dont have to be like this

it have to be like this

(but with transparent background)

Kicad only accept white lines for the PCB

[Rene_Poschl]

This might be because you have “negative” selected in the bitmap converter.
