Flatten transparency - Set opacity to 100% and use the colour closest to the transparant colour

[Intuos5]

Is there a way to flatten transparency from within Designer? I know you can do this on export, but what about modifying your current document?

One way to flatten would be via menu Layer > "Rasterize" or right-click the selected layer > "Rasterize". If more than one layer should get flattened you can group them first and apply "Rasterize".

[Intuos5]

So this means I cannot flatten transpararency without rasterizing my vector objects?

Can you explain what exactly do you mean by flatten transparencies?
if you don't want any transparent areas, but keep the file in vector format, just add a rectangular fill layer, and choose a color.

if you have semi-transparent areas, add a levels adjustment, select alpha channel, set offset to 100%

how do you define “color closest to non-transparent pixels” - can you give an example? 

Or do you have something different in mind?

Quoting from some Adobe docs:

At its simplest, the process of flattening converts all of the overlapping and interacting elements in a group of transparent objects into a collection of opaque elements that result in the same appearance as the original.

Note that this does not necessarily mean "rasterization". Illustrator is able to flatten transparencies while keeping everything as vectors.

I am not aware of an option to flatten vector within Affinity.

One workaround could be via Geometry > Divide to separate overlapping parts … but this appears to require reassigning of transparency and colours.

Another workaround would be to export as PDF –> flatten in an external editor (e.g. Acrobat) –> open the flattened PDF in Affinity.

v1105 .pdf –> v1105 flattened.pdf

I guess so, unless you do it manually (e.g. recording the blend values, then dividing, then applying the blend color values as opaque colors). It would be quite useful feature -- I am just checking if it is available in VectorStyler, but so far no joy. Affinity apps always rasterize transparencies also when exporting to PDF/X-1 or PDF/X-3  [in addition to also unnecessarily forcing conversion to CMYK] so you cannot use that method, either (you might of course have looked this feature to work around that omission, in the first place).

The workflow is that it can be easy to mute colours through opacity. For instance, with map making you may want to point out related landscapes with the same but muted colours (e.g. arable land and meadows). So you mute the colours with opacity and then flatten transparency to get the corresponding 100% non-transparent colour.

Hi @Intuos5,
No, Affinity apps do not flatten transparency other than through rasterising.

[Intuos5]

Thanks for chiming in @MEB

Is this something you could log for the developers? Or should I create a separate feature request for this? I mean, I could modify the first post and perhaps this thread could be moved over to the feature request section. It's not a high priority item, but it's nice to have nonetheless.

This is a feature (or at last improvement) request. It's better create a new thread in the Feedback for the Affinity V2 Suite of Products section.

[Intuos5]

Allright, will do so!
