Filters
Filters allow you to apply various effects to a selected raster layer.They cannot be applied to multiple selected layers.
You can also create a selection area to limit the effect of the filter to only that area.
Depending on the expression color of the selected raster layer, it may not be possible to apply certain filters.
Blur
These filters blur the image on gray and color raster layers.To use them, select the relevant layer and tap Filter > Blur.
Blur and Blur (Strong)
These filters calculate the average colors around borders and sharp edges to make the image smoothly blurred.
Gaussian blur
This filter converts borders and sharp edges to make the image smoothly blurred.You can adjust and preview the effect from the Gaussian blur dialog.
Smoothing
This filter applies anti-aliasing to the edges of the outline to make jagged lines less noticeable.Anti-aliasing smooths outlines by adding intermediate colors at the boundaries between colors and at the edges of images.
Radial blur
This filter blurs the image by smoothing and averaging it in a radial pattern.Selecting it displays the Radial Blur dialog and a red x mark on the canvas that shows the center of the effect.Drag the x mark to change its position.
