Convert Images from URL to Text via Ruby API
The open source OcrSpace library has included some powerful features for loading various types of images and convert them to text with a couple of lines of Ruby code. The library supports various OCR options, including extracting text from images, scanned documents, and PDF files. Whether software developers need to process invoices, receipts, or any other type of document, the OcrSpace Ruby library can handle it efficiently. The following example shows how software developers can convert images to text via URL using Ruby API.
Convert Images from URL via Ruby API
result = resource.convert url: "http://bit.ly/2ih9aXt"
puts result
=> #[{"TextOverlay"=>{"Lines"=>[], "HasOverlay"=>false, "Message"=>"Text overlay is not provided as it is not requested"}, "FileParseExitCode"=>1, "ParsedText"=>"If you want to find the secrets of the \r\nuniverse, think in terms of energy, \r\nfrequency and vibration. \r\nAZ QUOTES \r\n", "ErrorMessage"=>"", "ErrorDetails"=>""}]
result = resource.clean_convert url: "http://bit.ly/2ih9aXt"
puts result
=> #If you want to find the secrets of the universe, think in terms of energy, frequency and vibration. AZ QUOTES
Advanced OCR Capabilities via Ruby API
The open source OcrSpace library has included some very useful and advanced features for handling OCR operations inside Ruby applications. It can accurately recognize text from low-resolution images, distorted text, and even handwritten content, ensuring reliable results across various scenarios. Apart from text extraction, the library also allows developers to extract other important information from documents. This includes retrieving coordinates of the recognized text, detecting page numbers, and identifying specific areas of interest within the document.
