Zoom into your image to examine its edges; this may influence
the output type chosen.
Let's look at the output types and explain the difference between each.
Output Type Description and use
Alpha-edged
Bitmap
Vector-cropped
Bitmap
To create an 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.
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.
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.
