Working with Particle Shapes ❚❘❘ It is easy to create shapes from scratch. For example, you can use the Paint operator. Choose File | New and create a Paint branch with the desired image size (such as 128 x 128 pixels) and length (one or a few frames). Draw the artwork and rename the Paint operator to make it easy to find when you select this operator for the shape. Note: If you want to use a small portion of a large image, you may want to note its location while viewing the operator for the image so the crop position is easier to set in the Size fields. Or you can crop the footage using the Footage operator. To use an operator as a shape: 1. Select the particle type in the Workspace panel. 2. Click Shape to show the Shape controls. See Shape Controls. 3. Click Operator. The Operator Picker dialog appears. 4. Select the operator you want, and click OK. The name appears on the Operator button, the image (or image sequence) appears in the shape viewer, and the shape automatically becomes the shape for the particle type. Operator name on button 6. If you set Method to Crop, you can also set the Offset fields. The maximum X Offset is the width of the source image minus the Width setting. The maximum Y Offset is the height of the source image minus the Height setting. 7. From the left Channel list, select which channels to use as the source of the shape. For example, use RGB or RGBA depending on whether you want the alpha channel to be used by the shape. (This still applies to Gray shapes since the alpha channel can be added to the red, green, and blue channels to create the grayscale image for the Gray shape.) 8. From the right Channel list, select the color depth (Color or Gray). When a shape is set to Gray, the pixel value always represents the transparency (black is transparent, gray is semi-transparent, and white is opaque). For more information, see Choosing a Shape Type. Importing Shapes You can import the image or image sequence you want to use as a shape. When you import the shape, you can select the portion of the image(s) to use and set the color depth. Note: Importing a shape is not like importing footage into a composite. An imported shape appears in the shape library, not the Footage Library. 5. To decrease the size of the image(s), you either crop or resize it. By default, the method is set to Resize. For the Resize method, you can set only the Size fields. Use Lock to change the Size values proportionally. You cannot increase the size of the original shape. 369

Working with Particle Shapes
369
❚❘❘
It is easy to create shapes from scratch. For example,
you can use the Paint operator. Choose File | New
and create a Paint branch with the desired image size
(such as 128 x 128 pixels) and length (one or a few
frames). Draw the artwork and rename the Paint
operator to make it easy to find when you select this
operator for the shape.
Note:
If you want to use a small portion of a large
image, you may want to note its location while
viewing the operator for the image so the crop
position is easier to set in the Size fields. Or you can
crop the footage using the Footage operator.
To use an operator as a shape:
1.
Select the particle type in the Workspace panel.
2.
Click Shape to show the Shape controls. See
Shape Controls
.
3.
Click Operator.
The Operator Picker dialog appears.
4.
Select the operator you want, and click OK.
The name appears on the Operator button, the
image (or image sequence) appears in the shape
viewer, and the shape automatically becomes the
shape for the particle type.
5.
To decrease the size of the image(s), you either
crop or resize it. By default, the method is set to
Resize. For the Resize method, you can set only
the Size fields.
Use Lock to change the Size values
proportionally. You cannot increase the size of the
original shape.
6.
If you set Method to Crop, you can also set the
Offset fields.
The maximum X Offset is the width of the source
image minus the Width setting. The maximum Y
Offset is the height of the source image minus the
Height setting.
7.
From the left Channel list, select which channels
to use as the source of the shape.
For example, use RGB or RGBA depending on
whether you want the alpha channel to be used by
the shape. (This still applies to Gray shapes since
the alpha channel can be added to the red, green,
and blue channels to create the grayscale image
for the Gray shape.)
8.
From the right Channel list, select the color depth
(Color or Gray).
When a shape is set to Gray, the pixel value always
represents the transparency (black is transparent,
gray is semi-transparent, and white is opaque).

Choosing a Shape Type

Importing Shapes
You can import the image or image sequence you
want to use as a shape. When you import the shape,
you can select the portion of the image(s) to use and
set the color depth.
Note:
Importing a shape is not like importing
footage into a composite. An imported shape
appears in the shape library, not the Footage Library.
