Class SXSSFPicture

java.lang.Object

org.apache.poi.xssf.streaming.SXSSFPicture

All Implemented Interfaces:

Picture, Shape

public final class SXSSFPicture
extends Object
implements Picture

Streaming version of Picture. Most of the code is a copy of the non-streaming XSSFPicture code. This is necessary as a private method getRowHeightInPixels of that class needs to be changed, which is called by a method call chain nested several levels. The main change is to access the rows in the SXSSF sheet, not the always empty rows in the XSSF sheet when checking the row heights.

Method Detail

getCTPicture

@Internal
public org.openxmlformats.schemas.drawingml.x2006.spreadsheetDrawing.CTPicture getCTPicture()

Return the underlying CTPicture bean that holds all properties for this picture

Returns:

the underlying CTPicture bean

resize

public void resize()

Reset the image to the original size.

Please note, that this method works correctly only for workbooks with the default font size (Calibri 11pt for .xlsx). If the default font is changed the resized image can be streched vertically or horizontally.

Specified by:

resize in interface Picture

resize

public void resize(double scale)

Reset the image to the original size.

Please note, that this method works correctly only for workbooks with the default font size (Calibri 11pt for .xlsx). If the default font is changed the resized image can be streched vertically or horizontally.

Specified by:

resize in interface Picture

Parameters:

scale - the amount by which image dimensions are multiplied relative to the original size. resize(1.0) sets the original size, resize(0.5) resize to 50% of the original, resize(2.0) resizes to 200% of the original.

getPreferredSize

public XSSFClientAnchor getPreferredSize()

Calculate the preferred size for this picture.

Specified by:

getPreferredSize in interface Picture

Returns:

XSSFClientAnchor with the preferred size for this image

getPreferredSize

public XSSFClientAnchor getPreferredSize(double scale)

Calculate the preferred size for this picture.

Parameters:

scale - the amount by which image dimensions are multiplied relative to the original size.

Returns:

XSSFClientAnchor with the preferred size for this image

getImageDimension

protected static Dimension getImageDimension(PackagePart part,
                                             int type)

Return the dimension of this image

Parameters:

part - the package part holding raw picture data

type - type of the picture: Workbook.PICTURE_TYPE_JPEG, Workbook.PICTURE_TYPE_PNG or Workbook.PICTURE_TYPE_DIB

Returns:

image dimension in pixels

getPictureData
