Canvas Resize Issue

Recommended Posts

I sometimes have alpha regions after cropping images (TIFF files) and so I follow the procedure provided in the Affinity Photo--Canvas Resizing video/tutorial:

(1) Make sure that the Pixel Layer is Selected (in Layers)

(2) Mark out a proximate area with the Marquee Tool

(3) Contol-J, Control-D (to copy and then deselect the area)

(4) Using the Move Tool, drag the image to fill the alpha area.

The image that appears in Affinity looks fine, but when exported (as a JPEG), a fine line appears at the border of the Alpha area and the covering pixels. I know that this sounds a little confusing, so I attached a copy of an image that illustrates what I'm describing: look along the top from the rightmost corner moving left to the center and you should see a fine, straight white line.

Naturally, I'd prefer to extend the image when filling small alpha areas as opposed to loosing detail by additional cropping.

Any ideas would be appreciated.

 

Thanks
