Field Detail

EMU_PER_PIXEL

public static final int EMU_PER_PIXEL
In Escher absolute distances are specified in English Metric Units (EMUs), occasionally referred to as A units; there are 360000 EMUs per centimeter, 914400 EMUs per inch, 12700 EMUs per point.

MASTER_DPI

public static final int MASTER_DPI
Master DPI (576 pixels per inch). Used by the reference coordinate system in PowerPoint (HSLF)

Constant Field Values

PIXEL_DPI

public static final int PIXEL_DPI
Pixels DPI (96 pixels per inch)

Constant Field Values

POINT_DPI

public static final int POINT_DPI
Points DPI (72 pixels per inch)

Constant Field Values

DEFAULT_CHARACTER_WIDTH

public static final float DEFAULT_CHARACTER_WIDTH
Width of one "standard character" of the default font in pixels. Same for Calibri and Arial. "Standard character" defined as the widest digit character in the given font. Copied from XSSFWorkbook, since that isn't available here.

Note this is only valid for workbooks using the default Excel font.

Would be nice to eventually support arbitrary document default fonts.

EMU_PER_CHARACTER

public static final int EMU_PER_CHARACTER
Column widths are in fractional characters, this is the EMU equivalent. One character is defined as the widest value for the integers 0-9 in the default font.
