vue-image-zoomify

An image zooming feature for Vue, enabling zoom in and out functionalities.

An example gif using the feature.

• You can zoom in and out of the image by holding down the Ctrl button and using the wheel.
• This feature can also be enabled without pressing the Ctrl button through the options.
  
  

• This feature demonstrates the act of clicking the zoom in, zoom out, and reset size buttons at the bottom.
• The bottom buttons are provided by default and can be removed through options. Additionally, these buttons will only be activated when there is an image present.
  
  

• Resize the image to fit the element area.
• Maintain the original image size while adjusting the width or height to match the element size.
  
  

• Press the fullscreen button to view it larger
  
  

• This is an example of using a custom button.
  If you're not satisfied with the appearance or position of the button, customize it to your liking.
