Class SXSSFPicture

java.lang.Object
  org.apache.poi.xssf.streaming.SXSSFPicture

All Implemented Interfaces:

Picture, Shape

public final class SXSSFPicture
extends java.lang.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.

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()
