Magnify effect
The Magnify effect enlarges all or part of an image. This effect can act like a magnifying glass placed over an area of the image, or you can use it
to scale the entire image far beyond 100% while maintaining resolution.
This effect works with 8-bpc color.
Original (upper-left), and with variations of Magnify applied (lower-left and right)
The shape of the magnified area.
The center point of the magnified area.
Percentage by which to scale the magnified area.
How the Magnification setting affects the size and edge feathering of the magnified area. Setting Link to any value other than None disables
the Resize Layer option.
The size and edge feathering of the magnified area don’t depend on the Magnification setting.
The radius of the magnified area is equal to the Magnification value (a percentage) times the Size value.
The radius of the magnified area is equal to the Magnification value (a percentage) times the Size
value. The thickness of the edge feather is equal to the Magnification value times the Feather value.
The radius of the magnified area, in pixels.
The amount of edge feather, in pixels.
The opacity of the magnified area, as a percentage of the opacity of the original layer.
The type of scaling used to magnify the image:
This method maintains sharpness in the image but produces pixelated edges at higher values.
Uses spline algorithms. If you scale the image beyond 100%, Soft reduces edge pixelation and maintains image quality. Soft works
well at large magnification amounts.
Creates scatter or noise in the image as the image enlarges.
