azetina Posted November 29, 2021 Posted November 29, 2021 Consider the following example. For some reason or the other the image pixelates. Is this normal? The first diagram shows in Affinity and the other in pdf reader. can.afdesign can.pdf Quote
azetina Posted November 29, 2021 Author Posted November 29, 2021 Here is another case am getting weird outputs. Note that in Affinity it looks fine. In this example, it seems the mask is causing it. blurrybug.afdesign blurrybug.pdf Quote
thomaso Posted November 29, 2021 Posted November 29, 2021 The PDF export requires to rasterise the various "reflection" layers on each droplet because of their Gaussian Blur Effect. This effect is not part of the PDF specifications for vector transparency. Quote macOS 10.14.6 | MacBookPro Retina 15" | Eizo 27" | Affinity V1

Gaussian blur might stay vectorized (or can be forced to stay using an export setting), as can be outer shadow and glow. All the rest result in rasterization of output. Masked compositions often cause rasterizations in Affinity apps or might require specific compositions, and in combination of raster images, often also cause inadvertent upscaling. Using clipped constructions sometimes helps. blurrybug_clipped.afdesign blurrybug_clipped.pdf 379.11 kB · 1 download As a fix I had done something similar to what you suggest. Strange behaviour of affinity to do this. Quote

If yes, I can't find any blur – Can you point me to it? Quote macOS 10.14.6 | MacBookPro Retina 15" | Eizo 27" | Affinity V1

Yes, in the case of the reflections, a white-to-transparent gradient would work here as well – though that would be a lot of work in this existing document. However, such gradients cannot replace all common use cases of blur effects, even if especially for vector objects a simulation with gradients can be used as a substitute.

What would be the closest possible effect of a water drop that will not be rasterized? I would greatly appreciate a hack or suggestion. Quote
