Let's look at the output types and explain the difference between each.
Output
Type
Description and use
Alpha-
edged
Bitmap
Use when cutting out objects with poorly defined edges.
Transparency and pixel blending are used at the outline edge
to produce professional results with negligible interference
from background colors. The term "alpha" refers to a 32-bit
image's alpha transparency channel.
Vector-
cropped
Bitmap
Use on more well-defined edges. A cropped image with crop
outline is created which can be later manipulated with the
crop tools. You can optionally apply feathering to the image
edge but will not remove background color.
To create an alpha-edged bitmap:
1. Select Alpha-edged Bitmap from the Output Type drop-down menu.
2. (Optional) Drag the Width slider to set the extent to which the "alpha"
blending is applied inside the cutout edge.
3. (Optional) Adjust the Blur slider to smooth out the cutout edge.
To create a vector-cropped bitmap:
1. Select Vector-cropped Bitmap from the Output Type drop-down
menu.
2. (Optional) Drag the Feather slider to apply a soft or blurry edge
inside the cutout edge.
3. (Optional) Drag the Smoothness slider to smooth out the cutout edge.
4. (Optional) The Inflate slider acts as a positive or negative offset from
the cutout edge.
You'll need to click Preview in order to check output setting
adjustments each time.
