BaseImage

Barcodes found on the image.

Array of Encrypted local file identifiers of the image chunks, if the image split was requested using deliverables.localFile.split or deliverables.originalImageFile.split for corresponding image object. localFile will be set only if whole data is fit within single chunk.

This property is initialized to false. If set to true by the onImageAcquired handler, the image is discarded (deleted from the control's memory) when the handler returns.

Note, that this property is processed synchronously in onImageAcquired handler, i.e. if set in asynchronous operation callback, the change won't be reflected.

The resolution of the image, in DPI (Dots Per Inch), in an array of [horizontal dpi, vertical dpi ].

Flag indicating whether or not image is PDF or other eDoc.

If present, true when the image came from the front (top) side of a physical sheet, false for the back/bottom side.

If omitted, this information could not be confidently determined e.g. the scan is from a device that does not feed sheets.

Height of the image in pixels.

Imprinted text.

Encrypted local file identifier.

Number of bits used to represent a pixel (typically 1,8, or 24).

If present, this is true when this image came from a different physical sheet than the preceding image if any.

It is false if this image is the flip (back, bottom) side of the same sheet as the preceding image.

If omitted, it means this information could not be confidently determined.

Original image object metadata and local data storage identifiers.

Original image is stored to the local storage and removed from memory right after scan. Only image metadata(like width, height, pixelType, etc) and ImageBase#localFileChunks, ImageBase#localFile properties are valid.

'0', '1', '2', '3', '4', '6', or 'T'. The '0' value means 'no patch code detected'.

Note that the values are 1-character strings, but of course this is JavaScript so you can write either image.patchCode == '2' or image.patchCode == 2, as you wish.

When patch code detection is not enabled, the patchCode of each acquired image is '0'.

Atalasoft.Controls.Capture.WebScanning.scanningOptions = { onImageAcquired: _onImageAcquired, patchCodes: true }
// ...
function _onImageAcquired(eventName, image) {
  // Check patch code:
  if (image.patchCode == 'T') {
    // 'T' patch-code detected
  }
}

File path of the imported file.

Pixel type of the image.

If present, the index of the physical sheet within the scan job of which this is an image (front or back side).

The first sheet scanned is index 0.

If not present, this information could not be confidently determined e.g. the scan is from a device that does not feed sheets.

Width of the image in pixels.

X DPI the image.

Y DPI the image.

File path of the imported PDF file.

This property having value indicates that image proxy represents file format that is imported "As Is", i.e. PDF or eDoc. In this case image-specific properties are not present on such object and format change is not supported for it when requesting image data.

Gets an image as base64 string in the specified format.

Resets the image object to an empty state, releasing any (possibly large) internal memory being used to store pixel data. This is as close to a 'destroy' or 'dispose' method as we can get with a javascript object.

Saves an image as encrypted local file.
