CaptureVisionRouter Single Image Processing

capture

Process a single image or a file containing a single image to derive important information.

Syntax

capture(imageOrFile: Core.DSImageData | string | Blob | HTMLImageElement | HTMLCanvasElement, templateName?: string): Promise<Array<Core.CapturedResult>>;

Parameters

imageOrFile: specifies the image or file to be processed. It can be the image itself in the form of DSImageData, the path of the image/file or the file itself in the form of blob, HTMLImageElement or HTMLCanvasElement.

templateName: specifies a “CaptureVisionTemplate” to use. If not specified, “Default” is used. There are two types of CaptureVisionTemplates: the preset ones which come with the SDK and the custom ones that get initialized when the user calls initSettings. Please be aware that the preset CaptureVisionTemplates will be overwritten should the user calls initSettings and pass his own settings.
