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
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 colours. 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 colour.
You can also set the level of transparency and pixel blending at the cutout edge
by adjusting the output settings, Width and Blur. Control of the cutout edge lets
you blend your cutout into new backgrounds more realistically.
To create an alpha-edged bitmap:
1. Select Alpha-edged Bitmap from the Output Type drop-down menu.
2. (Optional) Drag the Wid th slider to set the extent to which the "alpha"
blending is applied inside the cutout edge. This creates an offset
region within which blending occurs.
3. (Optional) Adjust the Blur slider to apply a level of smoothing to the
region created by the above Width setting.
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.
