The Web API also supports rendering document pages to a variety of image formats such as PNG, JPG, BMP and GIF with the highest available accuracy and quality. Besides powerful reporting and conversion processes, the API method [/v1/templates/thumbnails](https://docs.reporting.cloud/docs/endpoint/templates/thumbnails) creates and returns images of document pages. It can be used for templates and resulting documents. If a document has been created using [/v1/document/merge](https://docs.reporting.cloud/docs/endpoint/document/merge) or [/v1/document/convert](https://docs.reporting.cloud/docs/endpoint/document/convert), you can [upload](https://docs.reporting.cloud/docs/endpoint/templates/upload) the document to your template storage in order to create the images using [/v1/templates/thumbnails](https://docs.reporting.cloud/docs/endpoint/templates/thumbnails). The following query parameters are available to specify the zoom factor, the format and to define the page range the images should be created for: | Key | Value Type | Value Description | |---|---|---| | templateName | String | The filename of the template in the template storage. | | zoomFactor | Integer | An Integer value between 1 and 400 to set the percentage zoom factor of the created thumbnail images. | | fromPage | Integer | An Integer value that specifies the first page. | | toPage | Integer | An Integer value that specifies the last page. | | imageFormat | String | A string value that defines the image format of the returned thumbnails. Possible values are PNG, JPG, GIF and BMP. | The following sample code shows how to create images using the [ReportingCloud .NET wrapper](https://portal.reporting.cloud/Wrappers/Dotnet/): ``` using System; using System.Collections.Generic; using System.Drawing; using TXTextControl.ReportingCloud; class RCSamples { public static void GetTemplateThumbnails(string templateName) { ReportingCloud rc = new ReportingCloud( "username", "password", new Uri("https://api.reporting.cloud")); try { List lstThumbnails = rc.GetTemplateThumbnails( templateName, 20, 1, 0, ImageFormat.PNG); foreach (Image img in lstThumbnails) { string sImageFilename = Guid.NewGuid().ToString() + ".jpg"; img.Save(sImageFilename, System.Drawing.Imaging.ImageFormat.Jpeg); Console.WriteLine("Image saved to: " + sImageFilename); } } catch (Exception e) { Console.WriteLine("An error occurred: " + e.Message); } } } ``` Start today with ReportingCloud and sign up for a [free trial account](https://portal.reporting.cloud/Account/Register/). --- ## About Bjoern Meyer As CEO, Bjoern is the visionary behind our strategic direction and business development, bridging the gap between our customers and engineering teams.
