How to restrict the image DAM upload based on aspect ratio of uploaded image?

[sureshy2015]

Hi,

We have a requirement of restricting the image upload based on aspect ratio.For example 3:2,16:9 should be allowed to upload and others need to be restricted.Is there any in built functionality to achieve the same or if any custom implementation required?.please help me for the same.

Hi 

You can achieve this by writing a custom component there you can create a logic to restrict image with aspect ratio.

Option 2

You can also create a component that can auto crop you any image

Option 3

Creation of custom aspect ratio component

Option  4

Set fixed aspect ratio for all images

//

The cropConfig node structure is what youre interested in. text="16x:10" is what will appear in the Crop dropdown, value="16,10" is the actual fixed Crop size for the tool. You can add as many predefined crops you want per html5smartimage widget.

The image-16x10 and aspectRatio-16x10 names aren't required, but not a useful convention to help in maintainability of the config.If you allow multiple aspectRatios then the image-16x10 naming probably doesnt make as much sense tho its not a bad idea to provide semantic naming to your aspectRatio definition node.

I hope this would help you.
