pixel tool misplaced

[piccolamimi]

i created a grid and want to design a pixel image. using the pixel tool, it snaps to the cross points of the grid, so i cannot fill the grid squares exactly. Whats wrong?

Document setup: 4000*4000px/ grid and snapping axis spacing 1px, divisions 1

Is this a Photo or Designer or Publisher Document?

Using Photo and the Pixel Brush tool I cannot achieve this problem.

Are you perhaps using Designer? Do you perhaps have a Bleed set? Is there an Artboard with bleed set?

Hi @piccolamimi welcome to the forums,

I'm also unable to replicate this using your described document setup, the pixel brush aligns perfectly with my grid, have you checked that your grid spacing is indeed set to 1px, and not 1.1px for example? Setting my grid spacing to 1.1px is the only way I can get the pixel brush to offset from the grid in a similar way to your screenshot.

As well as advising on what Old Bruce mentioned above, it would beneficial if you could provide us with your document.

This has been reported before for Publisher.

1. Create new DIN A4 document with facing pages
2. use Pixel persona
3. add pixel layer
4. activate grid
5. The pixel positions are misaligned, caused by a margin of 30mm which is no integer multiple of 1px at 300DPI

[NotMyFault]

Workaround: Don't use Publisher to create pixel art, use Photo or Designer instead and import final image into publisher. Extra effort may be required during export to avoid unwanted pixel misalignment.

thanks for all your your help. im using designer, not publisher.

 

• i Created new DIN A4
• used Pixel persona
• added a pixel layer
• activated grid
• How exactly would i change the margins so it works? if i disable the margins the Problem is still here

im using designer, not publisher. Yes there was a bleed set, but if i deactivate it the problem is still here

Hi @piccolamimi,

If you are using the Pixel Persona in Designer then you shouldn't have any issues using a 4000 px x 4000 px workspace...

Could you provide a screengrab of your workspace that shows the rulers or a screen recording showing the problem so we can see what might be going on...

In document setup:

Make document have pixels as units.
Have the document be 2481px / 3508px(rounding up mm to nearest px)
Make margins whole pixel position; 295 px or zero if not wanted.
Set bleed to zero or whole pixel position like 36px (rounding 3mm to nearest px)
Now use the pixel brush and it should work as intended.

okay but i use a german version. you should recognize though what the settings are:

Hi @piccolamimi,

Mirroring your settings I'm not seeing any issue with the pixels being misplaced on the grid... could you perhaps upload a sample Designer file where you see the issue so we can take a look at what else might be going on?

The document dimensions, margin and bleed are not relevant when setting this up in Designer, neither margin or bleed have any impact on the correct alignment of pixels when using the pixel brush in the Pixel Persona of Designer when using 1 px brush on a 1 px grid so there must be something else going on here.

There is a clear issue in Publisher as @NotMyFault pointed out earlier which I believe is already logged as a bug.

[Circulus]

Yes there's an issue that can be worked around.

Roundup the dimensions to whole pixels
And set the layer at whole pixels will do the trick.

Hi @piccolamimi,

The issue appears to be that your pixel brush is trying to snap to the existing pixels' bounding box in your document which is offset from the grid. If you delete the pixel layer in your document then the pixel brush works as expected and correctly aligns to your grid irrespective of your document dimensions...

 

[Circulus]

Yes it does, thanks.

 

[piccolamimi]

thank you very much guys for your help. the tip from RETURN finally fixed the problem. Thank you hangman too, i will also try what you are suggesting....

first expirience here, and a newbie with affinity.  this forum is awesome, so much help in a short time..seems that i should finally get rid of adobe;-)

Hi @piccolamimi,

The issue doesn't actually have anything to do with the document dimensions, it's a snapping issue which looks like a bug because disabling the relevant snapping options doesn't correct the issue...

With your file as supplied, if you either:

• Deselect the existing pixel layer in the layers panel, the pixel brush works correctly aligning to the grid
• Move the current pixel layer so it is pixel aligned, again, the pixel brush works correctly aligning to the grid

No, this time it is no snapping issue.

Snapping always uses document pixel position, and the layer was misaligned relative to the document grid. 

as soon as you pixel align the layer, everything is back to crystal sharp.

Exactly as I said three posts above...

I would suggest it is a bug, as in, it shouldn't matter whether or not the prior layer is selected or pixel aligned when using the pixel brush on a new layer. To me, this looks as though it is an issue where the pixels are offset when using the pixel brush based on the offset of the previously selected or misaligned layer, so the pixel brush is effectively either incorrectly snapping to a candidate or snapping to a visible object.

As soon as you either deselect the offset layer or pixel align the offset layer the pixel brush then works correctly so it is then snapping again, based on that layer but this time correctly.

The way it is implemented currently makes perfect sense. The pixel tool creates a 1x1 pixel in the active layer. Based on (default) bilinear view mode, the rendering gets blurry. Change view mode to nearest neighbor, and rendering gets sharp. All this has nothing to do with snapping.
