Transform in the vue Image Editor component

26 Mar 202524 minutes to read

The Image Editor provides a range of transformation options for manipulating both the image and its annotations. These options include rotation, flipping, zooming, and panning. These transformations offer flexibility in adjusting the image and enhancing its visual appearance.

Rotate an image

The Image Editor allows to rotate the image and its annotations by a specific number of degrees clockwise or anti-clockwise using rotate method. This method takes a single parameter: the angle of rotation in degrees. A positive value will rotate the image clockwise, while a negative value will rotate it anti-clockwise.

Note: It is recommended to pass values in multiples of 90° (e.g., 90, 180, -90) for proper rotation alignment.

Here is an example of rotating an image in a button click event.

Flip an image

The Image Editor provides the flip method, which allows you to flip both the image and its annotations either horizontally or vertically. This method takes a single parameter of type ImageEditorDirection, which specifies the direction in which the flip operation should be applied.

The Direction parameter accepts two values: ‘Horizontal’ and ‘Vertical’. When you choose ‘Horizontal’, the image and annotations will be flipped along the horizontal axis, resulting in a mirror effect. On the other hand, selecting ‘Vertical’ will flip them along the vertical axis, producing a vertical mirror effect.

Here is an example of flipping an image in a button click event.

Straighten an image

The straightening feature in an Image Editor allows users to adjust an image by rotating it clockwise or counter clockwise. The rotating degree value should be within the range of -45 to +45 degrees for accurate straightening. Positive values indicate clockwise rotation, while negative values indicate counter clockwise rotation. The Image Editor control includes a straightenImage method, which allows you to adjust the degree of an image. This method takes one parameter that define how the straightening should be carried out:

degree: Specifies the amount of rotation for straightening the image. Positive values indicate clockwise rotation, while negative values indicate counterclockwise rotation.

Here is an example of straightening the image.

Zoom in or out an image

The Image Editor allows to magnify an image using the zoom method. This method allows one to zoom in and out of the image and provides a more detailed view of the image’s hidden areas. This method takes two parameters to perform zooming.

zoomFactor - Specifies a value to controlling the level of magnification applied to the image.
zoomPoint - Specifies x and y coordinates of a point as ImageEditorPoint on image to perform zooming.

Minimum and maximum zoom level

The minZoomFactor property allows you to specify the minimum level of zoom that is allowed for an image. By setting this property, you can prevent the image from being zoomed out beyond a certain point, ensuring that it remains visible and usable even at the smallest zoom level.

By default, the minZoomFactor value is set to 0.1, meaning that the image can be zoomed out up to 10 times its original size.

The maxZoomFactor property is a useful feature in the Image Editor that allows you to define the maximum level of zoom permitted for an image. This property sets a limit on how much the image can be magnified, preventing excessive zooming that may result in a loss of image quality or visibility.

By default, the maxZoomFactor value is set to 10, meaning that the image can be zoomed in up to 10 times its original size. This ensures that the zooming functionality remains within reasonable bounds and maintains the integrity of the image.

Here is an example of specifying minZoomFactor and maxZoomFactor property in zoomSettings options in an image editor.

Panning an image

The Image Editor allows to pan an image when the image exceeds the canvas size or selection range. When zooming in on an image or applying a selection for cropping, it is common for the image to exceed the size of the canvas or exceed the selection range. So, the panning is used to view the entire image, by clicking on the canvas and dragging it in the direction they want to move.

In the following example, you can enable panning using the pan method in the button click event.
