How to crop an image to a rectangle in Salesforce Apex

Image cropping is a useful feature in many situations, but its implementation isn’t always the smoothest when working with Salesforce Apex. To put it bluntly, it’s a quagmire just waiting to suck you in for hours if you are not careful. Instead of dealing with that, how about I show you how to get cropping done fast using an API.

To use our API, first download this zip archive and copy the client folder into your Apex project:

https://github.com/Cloudmersive/Cloudmersive.APIClient.Apex.ImageRecognition/archive/master.zip

Now we will call our crop function and specify our dimensions and location of the crop:

SwagEditApi api = new SwagEditApi();
SwagClient client = api.getClient();
// Configure API key authorization: Apikey
ApiKeyAuth Apikey = (ApiKeyAuth) client.getAuthentication('Apikey');
Apikey.setApiKey('YOUR API KEY');
Map<String, Object> params = new Map<String, Object>{
'left' => 56,
'top' => 56,
'width' => 56,
'height' => 56,
'imageFile' => Blob.valueOf('Sample text file\nContents')
};
try {
// cross your fingers
Blob result = api.editCropRectangle(params);
System.debug(result);
} catch (Swagger.ApiException e) {
// ...handle your exceptions
}

And it’s as easy as that!
