Resize, Rotate, or Flip

Resize

Resizing can be applied to both the Document and the Canvas.

To resize the Document:

  1. Select Document | Resize Document... from the main menu.
  2. In the Crop dialog, enter values in the Width and Height fields then navigate to the New Dimensions field set and select one of the following measurement unit options from the drop-down:
    • Pixels: Resizes the image to specific dimensions in pixels.
    • Inches: Resizes the image to specific dimensions in inches.
    • Centimeters: Resizes the image to specific dimensions in centimeters.
    • Percent: Resizes the image to a percentage of the original.
  3. To maintain a specific width to height ratio, navigate to the Aspect Ratio drop-down and select any value other than "Aspect ratio not preserved". The following options from the Aspect Ratio drop-down list will preserve or set an aspect ratio:
    • Original: Maintains the original image's width to height ratio.
    • 1 x 1: Forces the width and height to be equal.
    • 2 x 3: Forces a width to height ratio of 2:3.
    • 3 x 2: Forces a width to height ratio of 3:2.
    • 3 x 5: Forces a width to height ratio of 3:5.
    • 5 x 3: Forces a width to height ratio of 5:3.
    • Custom...: Applies a custom ratio. Enter a width to height ratio in the Custom Aspect Ratio dialog box. Custom ratios are automatically saved to the Aspect Ratio drop-down list after clicking the OK button in the Custom Aspect Ratio dialog box.
  4. Optional: From the Anchor field, select an anchor to dictate the resizing starting point.
  5. In the Resolution field, enter a Dots Per Inch value to set image quality (the lower the number, the less quality).
  6. Do one of the following:
    • Click OK to apply any changes and close the Resize tool.
    • Click Cancel to discard all changes and close the tool.

Resize Document is a non-destructive scaling operation.

To resize the Canvas:

  1. Select Document | Resize Canvas... from the main menu.
  2. In the Crop dialog, navigate to the New Dimensions field set and adjust the options as described below.
  3. Click the OK button.

For more information, see Resizing the Canvas.

Resizing Options

Width Enter a numerical value for the image width.
Units Select a unit of measurement. Options include "pixels", "inches", "cm", and "percent".
Anchor For resizing the canvas only, select an anchor point for the resizing.
Height Enter a numerical value for the image height.
Aspect Ratio Make a selection from the drop down to either keep the image's original aspect ratio, to not preserve the aspect ratio, select a predefined ratio, or create a custom ratio.

Resizing Tips

Maintain image quality by reducing images only by 33%, 50%, or 66%. Other percentages can distort the aspect ratio.

Avoid resizing an image repeatedly. Each resizing places image pixels using a slightly different orientation. As a result, multiple resizes can change the overall color and appearance of the image. If a first resize attempt does not produce the desired result, click the Undo button.

Avoid increasing the size of an image. Increasing image size makes the image's pixels more apparent, causing a grainy effect.

Rotate

The document can be rotated to predefined angles or rotated to custom settings.

To rotate the document:

  1. Select Document | Rotate from the main menu.
  2. Make selection from options described below.

Rotating Options

180o Rotates the image 180 degrees.
90oClockwise Rotates the image 90 degrees in a clockwise direction.
90oCounter Clockwise Rotates the image 90 degrees in a counter clockwise direction.
Arbitrary... Opens the Rotate Canvas dialog where a custom angle for rotation can be entered and a rotation direction set.

Flip

Image's canvas can be flipped along the horizontal or vertical axis.

To Flip a canvas:

Depending on the type of flip desired, do one of the following,

  • Select Document | Flip Canvas Horizontal from the main menu.
  • Select Document | Flip Canvas Vertical from the main menu.
