Class BinaryGraphicsDocument

java.lang.Object

writer2latex.base.BinaryGraphicsDocument

All Implemented Interfaces:

OutputFile

public class BinaryGraphicsDocument
extends java.lang.Object
implements OutputFile

This class is used to represent a binary graphics document to be included in the converter result. I may also represent a linked image, which should not be included (and will produce an empty file if it is).

Constructor Detail

BinaryGraphicsDocument

public BinaryGraphicsDocument(java.lang.String sFileName,
                              java.lang.String sMimeType)

Constructs a new graphics document. Until data is added using the read methods, the document is considered a link to the image given by the file name.

Parameters:

sFileName - The name or URL of the GraphicsDocument.

sMimeType - the MIME type of the document

BinaryGraphicsDocument

public BinaryGraphicsDocument(BinaryGraphicsDocument bgd)

Construct a new graphics document which is a recycled version of the supplied one. This implies that all information is identical, but the recycled version does not contain any data. This is for images that are used more than once in the document.

Parameters:

bgd - the source document

Method Detail

isRecycled

public boolean isRecycled()

Is this graphics document recycled?

Returns:

true if this is the case

setData

public void setData(byte[] data,
                    boolean bIsAcceptedFormat)

Set image contents to a byte array

Parameters:

data - the image data

bIsAcceptedFormat - flag to indicate that the format of the image is acceptable for the converter

setData

public void setData(byte[] data,
                    int nOff,
                    int nLen,
                    boolean bIsAcceptedFormat)

Set image contents to part of a byte array

Parameters:

data - the image data

nOff - the offset into the byte array

nLen - the number of bytes to use

bIsAcceptedFormat - flag to indicate that the format of the image is acceptable for the converter

isLinked

public boolean isLinked()

Does this BinaryGraphicsDocument represent a linked image?

Returns:

true if so

isAcceptedFormat

public boolean isAcceptedFormat()

Is this image in an acceptable format for the converter?

Returns:

true if so (always returns false for linked images)

getData

public byte[] getData()

Get the data of the image

Returns:

the image data as a byte array - or null if this is a linked image

write

public void write(java.io.OutputStream os)
           throws java.io.IOException

Writes out the content to the specified OutputStream. Linked images will not write any data.

Specified by:

write in interface OutputFile

Parameters:

os - OutputStream to write out the content.

Throws:

java.io.IOException - If any I/O error occurs.

getFileName

public java.lang.String getFileName()

Get the document name or URL

Specified by:

getFileName in interface OutputFile

Returns:

The document name or URL

getMIMEType

public java.lang.String getMIMEType()

Get the MIME type of the document.

Specified by:

getMIMEType in interface OutputFile

Returns:

The MIME type or null if this is unknown

isMasterDocument

public boolean isMasterDocument()

Is this document a master document?

Specified by:

isMasterDocument in interface OutputFile

Returns:

false - a graphics file is never a master document

containsMath

public boolean containsMath()

Does this document contain formulas?

Specified by:

containsMath in interface OutputFile

Returns:

false - a graphics file does not contain formulas
