        public JpegImage(String name,
                 InputStream binaryContent)

        Creates new JpegImage instance from content, represented as byte stream, and with specified name

        Parameters:
        name - Name of the JPEG image. Cannot be null, empty or whitespaces.
        binaryContent - Content as byte stream. Reading begins from original position. Cannot be null. Should be readable and seekable. If this instance will be disposed, this stream will be disposed too.
        Throws:
        com.aspose.ms.System.ArgumentException
        com.groupdocs.editor.htmlcss.exceptions.InvalidImageFormatException

      • JpegImage

        public JpegImage(String name,
                 String contentInBase64)

        Creates new JpegImage instance from content, represented as base64-encoded string, and with specified name

        Parameters:
        name - Name of the JPEG image. Cannot be null, empty or whitespaces.
        contentInBase64 - Content as base64-encoded string. Cannot be null, empty or whitespaces. If it is not a JPEG content, exception will be thrown.

    • Method Detail

      • isValid

        public static boolean isValid(InputStream binaryContent)

        Checks whether specified stream is a valid JPEG image

        Parameters:
        binaryContent - Byte stream, that presumably contains a JPEG image
        Returns:
        True if specified stream contains valid JPEG image, false otherwise
      • isValid

        public static boolean isValid(String contentInBase64)

        Checks whether specified base64-encoded string is a valid JPEG image

        Parameters:
        contentInBase64 - Content of the presumably JPEG image in a form of base64-encoded string
        Returns:
        True if specified string contains valid JPEG image, false otherwise
      • isValidInternal

        public static boolean isValidInternal(com.aspose.ms.System.IO.Stream binaryContent)
      • reduceToNewHeight_JpegImage_New

        public final JpegImage reduceToNewHeight_JpegImage_New(int targetHeightInPixels)

        Creates and returns a new reduced JPEG image, but with specified new reduced height and proportionally reduced width.

        Parameters:
        targetHeightInPixels - Height of the desired JPEG image in pixels. Should be strictly lesser than original height.
        Returns:
        New JpegImage instance with specified height
