Usage

Follow the instructions below to get started with Aspose.OCR Cloud Micro App.

First run

At the first run, you must configure the credentials (see Signing up chapter above) the app will use to access Aspose.OCR Cloud.

Aspose.OCR.Cloud.CommandLineTool.exe config -clientid <your Client Id> -secret <your Client Secret>

The credential are saved to AsposeOCRCloudCLIConfig user environment variable. To update credentials, run the same command with the new Client Id and Client Secret.

Recognize an image and save result to file

IMPORTANT: Make sure to configure access credentials before performing OCR! See First run chapter.

Aspose.OCR.Cloud.CommandLineTool.exe recognizeimage -f image.jpg -o recognition.pdf -lang Portuguese

Command-line parameters:

• -f {source image path} (required) - absolute or relative path to the image file. The utility supports JPEG, PNG, single-page TIFF, GIF and BMP images.
• -o {target file path} (required) - absolute or relative path to the file in which the recognition results will be saved.
  Important: If the file extension does not match the file type specified in the -resultType parameter, the appropriate extension will be appended to the file name.
• -lang {language code} (optional) - recognition language code, for example Portuguese or HWT_eng.
  By default, image text is treated as English.
• -resultType {see values below} (optional) - format of the recognition result (by default, the results are saved as plain text):
  • Text - save recognition results to plain text file with line breaks. The extension of a file provided in -o parameter should be .txt. If the results file extension is different, the appropriate extension will be appended after it.
  • Pdf - the source image will be placed into PDF file with a transparent text overlay above it. The text will be selectable, searchable and indexable. The extension of a file provided in -o parameter should be .pdf. If the results file extension is different, the appropriate extension will be appended after it.
  • Hocr - save recognition results to hOCR file. The extension of a file provided in -o parameter should be .html. If the results file extension is different, the appropriate extension will be appended after it.
• -makeBinarization false (optional) - use this parameter to disable automatic conversion of the image to black-and-white.
  By default, the image is always converted to improve recognition accuracy.
• -makeSkewCorrection (optional) - set this flag to force automatic straightening of rotated images. By default, skew angle correction is disabled.
• -makeUpsampling (optional) - set this flag to automatically increase image resolution and enhance the contrast of text details. By default, smart upsampling is disabled.
• -dsrMode (optional) - specify document structure analysis algorithm:
  • DsrPlusDetector (default) - the combination of complex structure analysis and text area analysis.
  • DsrAndFilter - detect large blocks of text, such as paragraphs and columns. Optimal for multi-column documents with illustrations.
  • DsrNoFilter - do not analyze document structure for small images to maximize recognition speed; use complex structure analysis for large images only.
  • TextDetector - find small text blocks (individual words, phrases, or lines) inside complex images and then position these blocks relative to each other in recognition results. Works best with sparse irregular text and low-quality photos.
  • PolygonalTextDetector - automatically straighten curved or distorted lines and find small text blocks (individual words, phrases, or lines) inside the resulting image.
  • NoDsrNoFilter - Do not analyze document structure.

System requirements

Since all OCR tasks are executed in the cloud, the utility does not impose any specific hardware requirements.

The executable can run under the following operating systems:

• Microsoft Windows 10 or above.
• Microsoft Windows Server 2016 or above.

It requires .NET 6.0 to be installed. Other than that, it does not require any third-party components.

IMPORTANT: The host must have access to the Internet (api.aspose.cloud domain) and the application must be allowed through a firewall (outbound rule).
