Image scale is wrong when exported to Gerber

[Phantomx2]

Current Behaviour

When a PCB is exported to Gerber file the silkscreen images size are not matching the ones in fritzing. The images in the gerber file are always the same size no matter the size parameter in fritzing.

Bug.zip

Build: 1.0.3

Operating System: Windows 11

Steps to reproduce:

• Using the silkscreen image object, place an image on the PCB.
• Export to Gerber format
• Use Gerbv or another tool to view the Gerber file.
• Notice that the image size is wrong.

Expected Behaviour

The image in the gerber file should be the same size as in fritzing.

If applicable, an SVG can be used instead to avoid the scaling problem. To try this, I traced the bitmap with inkscape:

I am using an svg in the included file, it doesn't fix the issue for me. In fact, non-svg files just appear as black in my case.

In that case the SVG you are using probably contains a base64 encoded PNG image. It is not a vector graphic, although it is stored in a SVG container.

When I use the SVG from my previous post, scaling works:

Ho, I exported it from photoshop so you are probably right about that.

I created #4155 about the just black (sometimes also blank) image. The alpha channel is currently ignored.
