impossible to export slice in exact size

[monema]

I just can't export slices with the right mesure the frame takes a pixel too much.
No it's not a problem of pixel position. It's everything in whole pixel.
I need to send slice of interface to the client and i'm stuck with this.

What steps did you take to ensure this?

[monema]

IE. i got a group of circles it measure 71x71 ...the export slice is 72x72.

One of the files: Try to export by persona one of the buttons. you'll see 1 px difference between the two personas
Thanx

bug.afdesign

Ok great, it does with every shape even in new document.

Anyone?
PLEEEEASE HELP. (THANK YOU SO MUCH)

[Alfred]

The red ‘Home’ button is 71 by 71 but the grey one and all the other round ones are 70.7 by 70.7, and all of the objects have non-integer y coordinates. If you change all of the dimensions and coordinates to whole pixels, the sizes of the exported shapes should be correct.

[monema]

Alfred thanks, but no.
Have you seen the video?

Any shape has wrong size

I’m afraid the video didn’t play for me, so I simply opened your file and inspected the contents.

[monema]

Ok i zipped the video.
thanks

Thanks for the upload. Please go to ‘Edit > Preferences...’ and check the settings for decimal places: I think it’s labelled ‘Decimal places for unit types’ but I can’t check right now.

[monema]

yes this was the original problem i solved setting to zero the parameter since i dont need decimals for pixels.
But it's the same, just like you see in the video. The size are wrong.

That only controls the number of decimals that are displayed. If you put an object at a non-integer pixel position, say 70.1 it will then display as 70 but it is still really at 70.1.

You need to adjust the X/Y coordinates of all the objects, and their sizes, to make them integers. It's easiest to do that while you're building the file, by using the appropriate Snapping options (Force Pixel Alignment should be on, and Move by Whole Pixels should probably be off).

Or, at this point, you can set those snapping options and nudge each object a bit to get it pixel aligned (or use the Transform panel and type integer values for each object).

[monema]

I set zero to decimals
I make a new document
I make a simple shape and export persona give wrong dimensions.
I think you didn't see the video i just posted.
Thanks anyway.

[walt.farrell]

No, I didn't see the video.

But, again, that Preference setting is only for displaying sizes and coordinates. You are the one who needs to draw the items at the correct coordinates and sizes. What you need to do is set the Preference to a higher value, say 3 or 6. Then you will be able to see the actual sizes and coordinates.

Alfred has told you what you actually have in your .afdesign document, and I agree. Here, for example, is what I see in your .afdesign document for one of the circles:

With that non-integer Y coordinate that object would export with a height of 72px rather than 71px.

Here's the second red circle, with non-integer values for X, Y, W, and H. It, too, will export 1 px larger in the non-integer directions.

 

 

[monema]

Again: That is not the solution.
Please if you want to help, please spend 46 seconds and see the video.
Is anyone so kind to see the video where i just show how i draw a shape and,  in export persona the sizes result WRONG?
 

[Alfred]

I watched the video and I saw you drag out a rectangle at a seemingly random position on the screen. The Transform panel showed whole numbers for the coordinates and dimensions of that rectangle, but it is unlikely that the actual values were all integers unless you had the appropriate snapping options carefully set up.

Have you tried it? 

Many users have had your experience, and it is always the answer.

[monema]

Ok i see...thanks a lot, but can you explain how can i create a shape with no decimal coordinates? I have Whole pixel selected and qhen i create a shape the coordinates are in decimal...I think i'm goin mad.
And why in older Designer versions i never had this problem?
thank you so much

[PaRunk]

Hello,
When I create graphics for the web, where everything has to be created exactly, I use the grid that I have set with pixel spacing. Then you only have to activate the function that the objects can be aligned with the grid. Then the problem should be solved.

[monema]

WAIT A MINUTE. IT WAS THE ARTBOARD...the artboard coordinates were with decimals.
I don't understand why designer works like this.
Ok thank you so much for the help. 

[monema]

Other oddities, everything is set whole pixel and then whern i alt + drag an object to copy it, this take decimals in the coords. Even if the starting coordinates are WHOLE NUMBER.
If I move it, non problem if i copy + drag, back to decimals.
I think i'm dreaming.

Using Alt ioverrides the Snapping options when you move the copy.. You should duplicate the object (Ctrl+J, or Cmd+J on Mac) and move the copy, rather than using Alt, because you need the Snapping for your work. Or just use Ctrl (Cmd on Mac) rather than Alt, to make a copy and move it.

The modifier keys and their effects are shown in the Status Bar at the bottom of the window.

[monema]

The same if i change dimentions by boundin box. It loses snap. right?
Why in the world?
Anytime i change manually the size of an object i need to adjust the number...
In what world i need to use decimals in pixel by default.
it makes non sense at all.
Thanks for your time.

Hi monema,
Welcome to Affinity Forums
Enable Force Pixel Alignment in the main toolbar (the first icon in the magnet icon in the Snapping group) to ensure transforms to objects also snap to pixels when possible (objects where the ratio must be kept will rarely fall in integer values in one of the dimensions).

[monema]

Hi. No it just does not work most of the time.
I switched to a website layout project i'm making, and i take a look to the coordinates and dimensions of inside objects. They are all in decimals! Just because i needed to hand resize everything.

yes. and export persona goes crazy. I'm goin too.


Just in case, i'm doing this job since i was 20 and now i'm 42. I started to use AD because we all need an alternative to adobe, another point of view.
And because i'm truly passionate for new creative things.
So i started to use AD more and more until it became tragically slow ans sluggish in my PC (i've already open some threads) and now if this is the way to work, i think this is not the answer for me.
I've never fight for pixel decimals, or for phantomatic HALF pixels coming out from nowhere in my entire professional life.
Thanks a lot for the answer anyway.
