Instance Constructors

  1. new Blob(blobParts: Array[_], options: |[BlobPropertyBag, Dictionary[_]] = js.native)

    blobParts

    is an Array of ArrayBuffer, ArrayBufferView, Blob, DOMString objects, or a mix of any of such objects, that will be put inside the Blob.

    options

    is an optional BlobPropertyBag dictionary which may specify the following two attributes

  20. def size: Int

    The size, in bytes, of the data contained in the Blob object.

  21. def slice(start: Int = js.native, end: Int = js.native, contentType: String = js.native): Blob

    Returns a new Blob object containing the data in the specified range of bytes of the source Blob.

    Returns a new Blob object containing the data in the specified range of bytes of the source Blob.

    start

    An index into the Blob indicating the first byte to include in the new Blob. If you specify a negative value, it's treated as an offset from the end of the string toward the beginning. For example, -10 would be the 10th from last byte in the Blob. The default value is 0. If you specify a value for start that is larger than the size of the source Blob, the returned Blob has size 0 and contains no data.

    end

    An index into the Blob indicating the first byte that will *not* be included in the new Blob (i.e. the byte exactly at this index is not included). If you specify a negative value, it's treated as an offset from the end of the string toward the beginning. For example, -10 would be the 10th from last byte in the Blob. The default value is size.

    contentType

    The content type to assign to the new Blob; this will be the value of its type property. The default value is an empty string.

    returns

    A new Blob object containing the specified data from the source Blob.

    Example: 

    1. var blob = instanceOfBlob.slice([start [, end [, contentType]]]);
