Scale Image Tool

What it Does​

Resizes an imported image so that it matches real life. Use this when the image looks too big or too small compared to your draft, for example a photo of a pattern piece.

To do this, you mark a rectangle on the image whose real size you know, such as a ruler, a square on grid paper or a pattern piece with measured edges. You then type in the real width and height of that rectangle. The tool works out how much to enlarge or shrink the image, as a percentage, for the width and for the height.

If there are no images, a message tells you so and the tool closes. Import one first with the Import Image Tool or the Import PDF Tool.

How to Use​

  1. Activate the tool by clicking the Scale Image icon
  2. Select the image to scale from the list
  3. Click in the workspace on the top left corner of your rectangle. Click again to move the point, then select Continue
  4. Click the top right corner. This sets the width of the rectangle. Select Next
  5. Click the bottom right corner. This sets the height of the rectangle. Select Next
  6. Click the bottom left corner, then select Next. The four points are joined to show your rectangle
  7. Enter the real Width and Height of the rectangle, in the unit shown
  8. Check Drawn Width and Drawn Height. These show the size of the rectangle you marked. Correct them if they do not match, then select Next
  9. The tool shows Width Scale and Height Scale as percentages. Change either one if you want, then select Next
  10. The image is scaled. Select Save to keep it, or Cancel to discard the change
tip

Mark the corners as far apart as you can, on a rectangle with clear, straight edges. A bigger rectangle gives a more accurate size.

info

Width Scale is the real width divided by the drawn width, times 100. If the width and height percentages are different, the image is stretched in one direction.

info

The top left corner of the image stays where it is while the image changes size. You can scale the same image more than once. Each new scale is applied to the size the image has now.
