.exr exports from affinity photo are the wrong size and padded with black.

[Kenzor]

Under windows 10 using affinity photo 1.8.3.641 .exr exports from affinity photo are the wrong size and padded with black.

As a pro matte painter working in linear colour with affinity would be amazing but it needs to be reliable. My round trip is blackmagic fusion to affinity photo and back to blackmagic fusion.

• Opening the linear float Exr in affinity and painting is fine.
• The affinity photo export dialog shows the correct size
• However on opening the exported image ( in fusion nuke or affinity) it is much larger. 
• The borders of the original image are padded with Extra pixels.

The same issue is seen with the mac OS 

 

Clearly it's not an issue with Nuke, Fusion or the operating system. since the bug has been seen on different platforms and afftiny also fails to load the image correctly after  export.

Hi Kenzor,

How many extra pixels? Are you seeing decimals in the Transform box on the X and Y axis?

Can you attach the original EXR and the exported one?

It seems to be a problem with affinity loading  16bit float exrs.  When the image is exported after painting it becomes roughly 50% larger , the extra size is padded with black.

I'll need to go through my old projects to find an example.  the Images are under an NDA so i'd need to give you a private link
