Nik Viveza problem

[CarrotMan]

I'm disappointed to find that the weird colour problem with Nik Viveza seems unresolved still in Affinity, but I seem to be having another issue too. I cropped a photo, duplicated the layer and applied the Viveza filter, and find that not only does it have the usual colour problem, but that the filter layer is uncropped too (screen shots attached. Please ignore the first shot, which is just a duplicate of shot 2. And the fact that the shots seem to be breeding!!!).

Hi CarrotMan,

Unfortunately this is a known issue with the NIK Viveza plugin. This is something we would like to have fixed in the future.

Thanks

If you rasterize the layer first, then Viveza (and other Nik plugins) will recognize the crop. Usually!

@John Rostron

Thank you. I’m a bit confused by this because I thought that this image, an 8 bit TIFF which I converted from a raw in Canon DPP and then opened in Affinity, was by definition a rasterised layer, so don’t really understand why I would need to rasterize it. My knowledge is very limited, but reading up a bit on this my understanding is that one can have vector layers in Affinity which can be rasterized, and have to be for certain purposes, but if a TIFF is a raster format how can it be rasterized (or re-rasterized). Or has Affinity done something to “unrasterize” this TIFF? Please excuse my ignorance.

@CarrotMan, the rasterization fixes the cropping in a destructive manner. By default, the crop is non-destructive and can be reversed. If you do not rasterize (re-rasterize), then the plugin gets the entire image.

So, the pre-cropped image as loaded or developed was effectively rasterized as you had assumed and would load into the plugin OK.
