Parameters:

listener -

isVisible

public boolean isVisible(int r1,
                         int c1,
                         int r2,
                         int c2)

Determines if this image should be visible within the given visible area.

Parameters:

r1 - Row index of topmost row, 1-based

c1 - Column index of leftmost column, 1-based

r2 - Row index of bottom-most row, 1-based

c2 - Column index of rightmost column, 1-based

Returns:

true if the image should be visible inside the range, false otherwise

getWidth

public float getWidth(org.apache.poi.ss.usermodel.Sheet sheet,
                      int[] colW,
                      int defaultColumnWidthPX)

Calculates the width of the image. Might not be 100% correct because of bugs in POI (returns inconsistent values for Dx and Dy).

If the image doesn't have a specified width and should be sized to image file size, -1 is returned.

Parameters:

sheet - The sheet this image belongs to

colW - Array of column widths in pixels

defaultColumnWidthPX - Default column width in pixels

Returns:

Width of the image in pixels, or -1 if image file width should be used

getHeight

public float getHeight(org.apache.poi.ss.usermodel.Sheet sheet,
                       float[] rowH)

Calculates the height of the image. Might not be 100% correct because of bugs in POI (returns inconsistent values for Dx and Dy).

If the image doesn't have a specified height and should be sized to image file size, -1 is returned.

Parameters:

sheet - The sheet this image belongs to

rowH - Array of row heights in points

Returns:

Image height in points, or -1 if image file height should be used.

getId

public String getId()

Returns a unique ID of this overlay, used also as a resource key for images.

isVisible

public boolean isVisible()

Gets the visibility state of this overlay in the current spreadsheet view.

Returns:

true if overlay is visible, false otherwise

setVisible

public void setVisible(boolean visible)

Marks this as image visible or hidden in the current spreadsheet view. Only used for the spreadsheet to remember if data needs to be removed, doesn't affect real visibility.

Parameters:
