xfig: can't add jpeg or png images to drawing

[ruicortesao]

Dear All,

I have a macOS Sequoia 15.1.1 and tried to install xfig using the command:

sudo port install xfig

Apparently, the installation was smooth with no error messages. When I call xfig the program also pops up normally. However, if I try to add a picture to my drawing (jpeg, png, etc) I am not able to do it. I get errors like:

libpng error: IDAT: invalid distance too far back
corrupt JPEG data: 4092 extraneous bytes before marker 0xd3

I tried inserting several images without success.

I am only able to insert pdf images.

My old mac has an old xfig version, which works without problems.

Any thoughts about these issues?

Cheers.

Which version of the xfig port? (port -v installed xfig)

port -v installed xfig
The following ports are currently installed:
  xfig @3.2.9a_0 (active) requested_variants='' platform='darwin 24' archs='arm64' date='2025-01-12T10:34:47+0000'

I can confirm the error when including a PNG image. I get the same message. Let me have a look if this may be an upstream issue or something that was introduced with the latest port.

Follow up on the previous: I went back to the previous version of xfig (3.2.9) that we had in macports recently. There the same error pops up. I do not know if this is directly a problem with xfig, or its interface with the particular versions of libpng and libjpeg that macports is using. To be worked on.

Thanks for the update. Hope this problem can be fixed.

Is there a way to fix this problem?
