Some (random?) Exported PNGs are 5px off in length and width.

[james948]

I have 60 artboards and all are meant to be the same size. When I export as PNG however, most are 3755x5250px but about 10 are 3750x5750px 

I couldn't work out why they were doing this so I duplicated an artboard of one of the correct ones and copied and pasted the objects over to the correct one; exported again and what do you know, not only did it not correct it; ones that were 3755x5250px are now 3750x5750px 

I can't work out rhyme or reason.

Position and size is whole pixel?

Do you export using Export Persona? Are the individual Slice created correctly?

[walt.farrell]

Can you confirm those sizes again, James. You've said they're 5px off in length/width, but one of your numbers changed from 5250 to 5750, which is 500px.

[james948]

Yes. Sorry my bad. 

Here's what I'm currently getting 

3755x5250

3750x5250

I didn't know about whole pixel position and size

When I select a layer "Absolute Sizes" is not ticked. 

How do I turn on whole pile position and size for all layers?

 

Meanwhile, yes, I'm using the Export Persona. The individual slices are artboards so I believe they're created correctly.

Select an Artboard and look at the Transform Panel.
If the X, Y, W and H are not all integers then your export will be larger than the artboard because the software has to ‘invent’ extra pixels to cope with the ‘overlap’.
(Not sure why you would get five extra pixels but making sure you’re using integers the first thing to look at.)

[james948]

The transform panel has been confusing me!

Isn't the transform panel simply showing me where in space the artboards are? I believed that all the objects inside the artboard would have X and Y coordinates relative to the artboard, not relative to the document as a whole but it seems that's not the case.

I can see why the W and H must be whole numbers but not the X & Y.

Does this mean I must move the artboards in the space until they are whole numbers?

See a few attached screenshots. 

Thanks for the help

Unfortunately yes, you will have to move the artboards.
The artboards are positioned within an overall ‘canvas’ workspace which is set to a specific DPI (Document Setup) and it is these pixels that the artboards need to be aligned to. I don’t know why, but you get used to it after a while.
You can set “Force Pixel Alignment” (Toolbar Icon) to make sure all new items automatically have integer positions.

[james948]

Great. Thanks so much for your help. 

It probably makes sense somehow but it seems odd that the placing of the artboards on the canvas would have some effect on their size when exported. 

Is there a way of telling them to be independent from the "canvas dpi" but still remain inside the canvas? 

I'm sure there's a reason for it but it's frustrating when I'm working in an artboard and I want an object to be 50px from the left of the artboard and I have to say X+10 and assume that the weird number it generates is right, you know?

 

[james948]

Hmm. Still having problems. They don't seem to snap to whole pixels (perhaps it's bc I'm looking at pts (just realised) and not px)

Must I do it manually for every one?

[GarryP]

Sorry, I was reading "px" instead of "pt" in your screenshots too. The px values should be integers if you change the UOM to pixels.
As far as I know there’s no way to make the artboards independent from the canvas, think of it as one large document – what the DPI refers to – with artboards spread about on it.
In this case, if you have “Force Pixel Alignment” switched ON, make sure you have “Move by Whole Pixels” switched OFF.
You might be able to select all the artboards and move them a tiny bit to get them aligned but I haven’t tested that. Edit: Don't think that works.

I’ve just checked and you might need to set Snapping OFF to get “Force Pixel Alignment” to work in this case, otherwise it seems to snap to the other artboards by default. Also, you need to move each artboard individually.

[james948]

Hoorah. I had to change to pixels and just manually delete the decimals in every one. 

Holy cow that was a pain; tbh when I export an artboard I don't expect where it lies on the canvas to have any effect on its size; I can see why this happened now but I still think it's counterintuitive. Particularly since "whole pixels" and "snapping" and "force pixel alignment" have to be used and understood in concert to try and get the export at the right size! 

Baffling! 

 

That being said thanks for helping me get to the bottom of it! Much appreciated!😁

[GarryP]

You’re welcome.
I understand what it’s like to get confused by this but I can’t see Serif changing the way things work at this point in the game. (Maybe I’ll be proved wrong.)
Glad you’ve been able to get it fixed though. (Still don’t know why you were getting five extra pixels. Would have expected two at most, but not five.)

[james948]

Yeah I thought about that. I think it's because I was exporting at 5x size. 

So the margin for error got larger.

Just one artboard will always show 0/0 position

It's possible for no Artboard to be at (0, 0) if there are multiple Artboards.
