White/Grey Stripes on PDF PCB export #3246

Closed YaseenTwati closed 10 months ago

YaseenTwati commented 8 years ago

white stripes over the copper filled parts of a pcb

grey stripes

I dont really need to explain just look at the picture ( open it ), this happens with almost all of my boards whenever i export a pdf. Since im home etching i can just open gimp and paint them one by one using the bucket tool, but its an just an extra annoying step when dealing with a complex double sided PCBs there has been older discussions about it before

but it looks like it hasn't been fixed

aknoerig commented 8 years ago

Sorry, but don't worry about these! They are just rendering artefacts and won't affect your print or production. The copper fill is created with a scanline algorithm, so it's basically hundreds of black rectangles stacked vertically. There is no gap between them, though, but the PDF viewer sometimes displays them as 1px white/grey lines.

YaseenTwati commented 8 years ago

Well yes they don't effect the circuit, but they do affect my etch, not sure if that has to do with me choosing the highest quality when printing but yeah as i said they still do. anyways to prove what Im saying I grabbed a camera and took a picture of a print lol :D

Thanks for the photo! Hmm, they are indeed visible.. We'll look into that again, but it's not a high priority since we haven't heard of any issues with it. These lines are too thin for the etching process to have any effect.

rmisko11 commented 4 years ago

They sometimes affect the continuity of my ground plane. 😡 I thought I saw somewhere that someone had a fix a few years ago?

KjellMorgenstern commented 4 years ago

@rmisko11 Do you have a chance, eg. a VM or a second computer, to try this with the development version of Fritzing (0.9.5 develop, available at github releases for Linux and Mac)? Also, if you have a simple project that reproduces the issue, it would be really helpful to attach it to this issue.

rmisko11 commented 4 years ago

I have just 0.9.4 and the problem still exists as shown in attached image. MagneticStirrer_A4988_etch_copper_top_mirror_1

rmisko11 commented 4 years ago

Kjell, Thank you for your interest. I just tried 0.9.5 with the same result. I am a simple project as you requested where you should be able to replicate the bug by simply exporting pdf. I am using Ubuntu 18.04 LTS. SimpleProject.zip

KjellMorgenstern commented 4 years ago

An improvement which on the side fixed this issue was integrated with PR #3203 (going back to #3083) but had to be reverted.

aknoerig commented 4 years ago

Fwiw, note that the panelizer that was originally blocking #3083 is no longer used and likely won't be used again. (It was part of Fritzing Fab before Aisler)

rmisko11 commented 4 years ago

Is there a plan to fix this soon?

KjellMorgenstern commented 4 years ago

We have not forgotten about this. Integrating the new export brings a lot of improvements (not only fixing those stripes) and will certainly be done.

rmisko11 commented 4 years ago

Thanks for the rapid response.

Would you be able to give some indication of when the new export might be implemented?

Well, let me guestimate :-) Hacking sessions to integrate it: 1 weekend Testing and fixing other things that might have broken: 4-8 weeks Roll out the release: 2 weeks

But before I can start, there is the following

With that timeline, we end up at end of July as the earliest date for official support, but on the development branch it would already be in May. All quite optimistic estimates.

rmisko11 commented 4 years ago

Great Kjell, I look forward to it. Thanks.

I just downloaded and tried version 1.02 and the horizontal stripes are still present in the PDF.

Am I to assume that since #3246 is marked completed that there is no intention to fix the horizontal stripe problem in PDF?

@rmisko11 How did you generate the copper fill, did you use the old or the new algorithm?

rmisko11 commented 10 months ago

Thank you for responding so quickly, I think I used the old one, I will try it again now and get back to you.

Thank you very much, I just did it with the new ground fill and it seems to work perfectly.

Thanks again, Roger
