defaultColumnWidthToPx

public static int defaultColumnWidthToPx(int columnWidth,
                         int charWidth)

Convert default columns width (in character) to pixel. 5 pixels are margin padding.(There are 4 pixels of margin padding (two on each side), plus 1 pixel padding for the gridlines.) Description of how column widths are determined in Excel (http://support.microsoft.com/kb/214123)

Parameters:

columnWidth - number of character

charWidth - Using the Calibri font, the maximum digit width of 11 point font size is 7 pixels (at 96 dpi).

Returns:

width in pixel Rounds this number up to the nearest multiple of 8 pixels.

pxToDefaultColumnWidth

public static int pxToDefaultColumnWidth(int px,
                         int charWidth)

Convert default column width in pixel to number of character by reverse defaultColumnWidthToPx() and ignore the mod(%) operation.

Parameters:

px - default column width in pixel

charWidth - one character width in pixel of normal style's font

Returns:

default column width in character

incheToPx

public static int incheToPx(double inches)

pxToInche

public static double pxToInche(int px)

pxToCTChar

                             int charWidth)

Convert XSSF default columns width (in character) to pixel. In XSSF the value is a double value / charWidth and includes the 5 pixels margin padding. 5 pixels are margin padding.(There are 4 pixels of margin padding (two on each side), plus 1 pixel padding for the gridlines.) Description of how column widths are determined in Excel (http://support.microsoft.com/kb/214123)

Parameters:

columnWidth - number of character

charWidth - Using the Calibri font, the maximum digit width of 11 point font size is 7 pixels (at 96 dpi).

Returns:

width in pixel
