Some part are missing while exporting to png files

[may23]

Hi 
My vers 1.10.6.1665

I am trying to export my Illustration to png files but didn't work.
It can't fully export the whole images. Some part are missing and I don't understand why. 

Do you have any idea why or how to fix this?


Thanks
MW

Welcome to the forum @may23 odd, I can export to png fine.

Fig .1 png file 8bit dithered from Affinity designer V1.10.6

 

Maybe show your png export settings.

Does this file export correctly in any other format on your system?

If so, try exporting to PDF or TIFF or SVG and then opening one of those formats in Affinity Designer v1 and seeing if it exports to png 8bit dithered correctly.

As you are using a palletized export, i would recommend to add a rectangle in white as bottom layer, or use the matting option in export.

For me it exports correctly on iPad with V1. 

You may try to deactivate HW acceleration in Preferences.

Nothing to do with it. The parts are missing ONLY when using "Selection Only" in the export dialogue. So the OP can work around by adapting the artboards size to the content or using "Selection Area".

Here are my export setting.


I just want to export it without the white background. Only the character. But doesn't work when I choose "Selection Only".
I already try to export to another format as you suggested. It works but it is just like JPEG files, where the white Background still appears.

Seems I cant find the "matting" option in export. 
When you export it does the white background also there? I don't want the white background. 
My HW acceleration is off

Yes. You're right. I use "Selection Only" in the export dialogue. I tried using the Selection Area but it still show the white background.

Go to File > Document setup... Colour Tab and check Transparent Background

That should give you a transparent background for export.

Standard png is your best option with transparency included and a smallish file size, albeit almost 3 times the size of a palletised export with approximate file sizes for none palletised being 480kb vs 178kb for palletised.

You could use online or offline image compress apps and you will be able to get the file size down considerably if that is needed.

This looks like a bug and it's the same in V2... Pixel values that are showing as transparent on the 8-bit version have identical colour values to other areas that are not shown as transparent, e.g., the yellow t-shirt, dress and legs...

As others have mentioned, exporting as a 24 bit PNG works as expected and doesn't demonstrate the issue...

If it is essential for the file to remain in 8 bit then you could edit in Photo (if you have access to Photo), make an alpha selection from the channels palette and load it as a pixel selection to a new pixel layer and then give it a white fill and place this layer behind your graphic.

That way you will be able to successfully export it as an 8 bit PNG with background transparency.

This is how you could achieve this (Note: I'm using V2 for the screen recording but the process is identical in V1)... obviously if file size is the key issue  select the layer in the Layers Panel first and use Selection Only when exporting to reduce the exported dimensions of the exported file to that of just the graphic...
