Artboards | Unwanted bleedings

[Ruslan TV]

Hi! I have a bug with the canvas export behavior. There are unwanted bleedings appearing during export if you have some effects that go beyond the artboard borders. I tested with perspective transform, Gaussian blur, and Lens blur. Please check my video.

Hi @Ruslan TV,

This is already logged under AF-561 and is still awaiting a fix...

 

[Ruslan TV]

@Hangman Nope. This is about export. The exported image has a margin matching the size of the effects extending beyond the artboard.

@Ruslan TV,

With you now... though I can't replicate it on Mac or Windows...

[Ruslan TV]

@Hangman This is an unwanted margin, its appeared out of nowhere. On the right artboard, it appears as transparent pixels in the exported image.

@Ruslan TV, can you upload a sample Affinity file so we can see what is going on?

[Ruslan TV]

@Hangman Here, you are. Try to export.

@Ruslan TV

Perfect thank you… I’ll take a look once back in the studio tomorrow and let you know if I see the same issue…

@Ruslan TV,

It appears to be purely the Live Blur Filters causing the issue when you edit the blur radius of the Filter itself...

For each one-pixel radius (or degree in the case of radial) applied, the following number of pixels are added to the size of the slice on a linear scale... so applying a 2 px radius will double and a 3 px radius will triple the number of pixels added to the Slice width and height which I'm assuming it should do...

• Gaussian Blur - 6 px
• Box Blur - 2 px
• Median Blur - 2 px
• Bilateral Blur - 4 px
• Motion Blur - 2 px
• Radial Blur - W: 20 px, H: 34 px
• Lens Blur - 2 px
• Depth of Field Blur - 2 px
• Field Blur - 2 px
• Maximum Blur - 2 px
• Minimum Blur - 2 px

Zero Pixel Radius Top | One Pixel Radius Bottom

 

With your sample file delete any existing slices and then set the Gaussian Blur radius to zero or delete the layer completely and the slices appear at the correct size. Simply toggling the layer visibility off doesn't work...

Alternatively, if you position the Blur Filter on an independent layer rather than editing the Filter, everything works as expected and the correct slice size is created...

This isn't unique to the Beta, the same behaviour is exhibited in the 2.5.6 Retail version on both Windows and Mac... I suspect this has likely always been the behaviour...

Hopefully, someone in the moderation team will pick this up and log it as a bug...
