Constructor Detail

EmfImage

public EmfImage(String name,
                InputStream binaryContent)

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

Parameters:

name - Name of the EMF 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

EmfImage

public EmfImage(String name,
                String contentInBase64)

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

Parameters:

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

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

Throws:

IllegalArgumentException

Method Detail

dispose

public void dispose()

Disposes this EMF 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 EMF image as a binary stream

Specified by:

getByteContent in interface IHtmlResource

Overrides:

getByteContent in class VectorImageResourceBase

getTextContent

public String getTextContent()

Returns a content of this EMF image as a plain text

Specified by:

getTextContent in interface IHtmlResource

Specified by:

getTextContent in class VectorImageResourceBase

Returns:

getType

public ImageType getType()

Returns ImageType.Emf

Specified by:

getType in interface IHtmlResource

Specified by:

getType in interface IImageResource

Specified by:

getType in class VectorImageResourceBase

Returns:

isValid

public static boolean isValid(InputStream binaryContent)

Checks whether specified stream is a valid EMF image

Parameters:

binaryContent - Input byte stream. Cannot be NULL, should support reading and seeking.

Returns:

True if specified stream holds a valid EMF image, false otherwise

isValid

public static boolean isValid(String contentInBase64)

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

Parameters:

contentInBase64 - Input string, where content of EMF image is stored in base64 encoding. Cannot be NULL or empty.

Returns:

True if specified string holds a valid EMF image, false otherwise

save

public void save(String fullPathToFile)

Saves this EMF image to the file

Specified by:

save in interface IHtmlResource

Specified by:

save in class VectorImageResourceBase

Parameters:

fullPathToFile - Full path to the file, which will be created (if it doesn't exist) or overwritten (if exists) with the content of this EMF image

saveToPng

public void saveToPng(OutputStream outputPngContent)

Saves this vector EMF image into raster PNG image

Specified by:

saveToPng in class VectorImageResourceBase

Parameters:

outputPngContent - Output stream, into which the content of PNG image will be written. Cannot be NULL and should be writable.

saveToSvg

public void saveToSvg(OutputStream outputSvgContent)
