Do the following

Drag a side handle to resize the layer in one direction only.

Drag a corner handle to resize the layer in two directions at once. If you want to maintain the layer proportions, hold down Shift as you drag. The pointer changes when you position it over a corner handle if.

Do the following

Rotate a reference layer

Hold down Command (Mac OS) or Ctrl (Windows), and drag a corner handle. The pointer changes when you position it over a corner handle Q*.

Skew a reference layer

Hold down Command (Mac OS) or Ctrl (Windows), and drag a side handle. The pointer changes when you position it over a side handle "i.

To set reference layer options

1 Select a reference layer.

2 Choose Effects menu > Orientation > Set Transform.

3 In the Set Transform dialog box, adjust any of the following settings:

• Retain Alpha works with placed images to retain the file's alpha channel. When the image is placed, the channel becomes the layer mask. Disable this option to discard the channel.

• Horizontal and Vertical define the scaling relationship between the reference layer and the source layer. If the scaling is low, 33% for example, and you increase it, Corel Painter refers to the source layer to obtain more pixel data.

• Constrain Aspect Ratio maintains the proportions of the image. Disable this option to distort the image proportions.

• Rotation and Slant rotates or slants the layer based on an original position of 0°. Enter positive values to rotate or slant the layer counterclockwise; enter negative values to rotate or slant the layer clockwise.

• Fast sets a high sampling ratio to produce a low-resolution reference layer. A low-resolution reference layer contains less information, so it can be transformed quickly.

• Clean sets the sampling ratio at 1 to 1 to produce a reference layer of the highest possible resolution — up to that of the source. This shows a better image as you work, but takes much longer to calculate transformations.

The Quality setting (Fast or Clean) applies only to the quality of the reference layer. When you convert a reference layer to a pixel-based layer, Corel Painter resamples the original image to produce the best possible resolution.

Reference Image shows the pixel dimensions of the original image. This is static information — you can't change the Reference Image values.

To commit a reference layer

1 Select a reference layer.

2 Choose Effects menu > Orientation > Commit Transform.

The conversion process might take a few seconds, depending on the size and quality of the layer.
