SDKs

Using an SDK (API client) is the quickest way for a developer to speed up the development. An SDK takes care of a lot of low-level details of making requests and handling responses and lets you focus on writing code specific to your particular project. Check out our GitHub repository for a complete list of Aspose.Imaging SDKs along with working examples, to get you started in no time.

SDK Examples

.NET

	// For complete examples and data files, please go to https://github.com/aspose-imaging-cloud/aspose-imaging-cloud-dotnet
	protected void AddImageFeaturesToSearchContext(string storageSourcePath, bool isFolder = false)
	{
	var request = isFolder
	? new CreateImageFeaturesRequest(this.SearchContextId, imageId: null, imagesFolder: storageSourcePath, storage: null)
	: new CreateImageFeaturesRequest(this.SearchContextId, imageId: storageSourcePath, storage: null);
	this.ImagingApi.CreateImageFeatures(request);
