Hi, I just installed Kicad 7. When I print logic gates they show a weird symbol within.
First image is a snip from the schematic editor; second image is from the “print preview”.
I have no clue on what’s going on; I tried googling around but I cannot find the right words to describe this behavior (not a native english speaker here).
I know really nothing about how graphic acceleration works but can’t it be connected with using/not using Accelerated graphics. May be some incompatibility between KiCad asking graphic card to accelerate some task and how that task is really done.
It can be changed in Preferences - Preferences - Schematic Editor - Display Options - Rendering Engine.
I experience the same issue with 4xxx series. The symbols come from the standard libraries, I did not tamper with them. See the jsut-added symbols here:
Thank you, Piotr!
I will try to disable acceleration.
As I just wrote to jmk, Kicad 6.x did not show this weird behavior. I am sure that Kicadf 6.x graphic acceleration was enabled.
You said you have the same bug when you export them to PDF (print and then select PDF printer)? Can you upload a PDF with this bug? (just to make sure it is a problem of KiCad or export, not a problem of your PDF reader and print preview of your OS).
You have at least 2 options to create a PDF, one is by using ctrl-P or Datei → Print and later you select Print as File and export a PDF. The other is by clicking Datei → Plot. Do you have the same problem in both of them or only with ctrl-P?
On “File / Plot / PDF” the printout is fine.
On “File / Print / Print to MS PDF printer” I get the issue as snipped from Adobe Reader.
Odd enough, I just discovered that “File / Print / Print Preview” in Black/White shows no issue.
I am a bit puzzled. As I said, I never got this behaviour with Kicad 6, that I removed last weekend and installed v7.
@andreamazzai : I think you have discovered a bug in the printing-code, I have replicated the unwanted lines in the print-output for two diffferent virtual pdf-printer drivers (edocprintpro & MS_Print_to_pdf).
I see this behaviour on version v7.0.5, but not on the development version v7.99
If you want you could open a gitlab-bugreport, this bug is well suited for a first bugreport (reproducible, can be good explained with some pictures).
For such a bugreport:
use the integrated command Kicad–>Help–>Report bug. This opens a prepopulated gitlab issue with the kicad-version already filled in.
Attach a simple example project (Kicad main manager -->File–>Archive project) which contains a schematic with your 4001/4011 symbols
include two pictures side by side as comparison: view from the kicad-canvas (with good looking symbols) and than the disturbed picture fro the pdf-output
fill out the “reproduction steps” as detailed as possible (not only “print to pdf”, but with click this button, click this, use this checkbox → than get this or that result)
If not already, you will have to register with Gitlab before reporting the issue.
This is only a few painless minutes. Follow @mf_ibfeew 's instructions “Kicad > Help > Report bug”, then you will be asked to either log in, or create an account. Just follow the instructions.
