Constructor Detail

WmfImage

public WmfImage(String name,
                InputStream binaryContent)

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

Parameters:

name - Name of the WMF 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

WmfImage

public WmfImage(String name,
                String contentInBase64)

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

Parameters:

name - Name of the WMF image. Cannot be null, empty or whitespaces.

contentInBase64 - Content as base64-encoded string. Cannot be null, empty or whitespaces. If it is not a WMF content, exception will be thrown.

Throws:

IllegalArgumentException

InvalidImageFormatException

Method Detail

dispose

public void dispose()

Disposes this WMF image by disposing its content and making most its methods and properties non-working

Specified by:

dispose in interface IDisposable

Specified by:

dispose in class VectorImageResourceBase

getByteContent

public InputStream getByteContent()

Returns a content of this WMF image as a binary stream

Specified by:

getByteContent in interface IHtmlResource

Overrides:

getByteContent in class VectorImageResourceBase

Returns:

getTextContent

public String getTextContent()

Returns a content of this WMF image as a plain text

Specified by:

getTextContent in interface IHtmlResource

Specified by:

getTextContent in class VectorImageResourceBase
