Constructor Detail

JpegImage

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:

IllegalArgumentException

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.

Throws:

IllegalArgumentException

InvalidImageFormatException

Method Detail

getType

public ImageType getType()

Returns ImageType.Jpeg

Specified by:

getType in interface IHtmlResource

Specified by:

getType in interface IImageResource

Specified by:

getType in class RasterImageResourceBase

Returns:

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
