Field Detail

EN

public static final int EN

Rough size of the typographic en space, in pixels. Calculated as EM/2.

An en space is one-half the width of an em space... [http://atlas.gc.ca/english/carto/type.html]

EM

public static final int EM

Rough size of the typographic em space, in pixels. Calculated from the platform default font, making it suitable for gross-scale layout.

An em space is the square of the body of the printed type being used. In twelve-point type an em would be 12 x 12 points, in ten-point type an em would be 10 x 10 points, and so on. The expression is derived from the letter 'm' which is the widest letter in the lower-case alphabet. [http://atlas.gc.ca/english/carto/type.html]

"Em's are typically used for font-relative horizontal sizes." [http://www.w3.org/TR/MathML2/appendixh.html]

Method Detail

largest2PowerFractionalPointSize

public static float largest2PowerFractionalPointSize(Font baseFont,
                                                     String referenceString,
                                                     Dimension2D maxDimension,
                                                     FontRenderContext fontRenderContext)

Returns:

same as largest2PowerPointSize but search is further restricted to sizes that are less than or equal to baseFont's size [never tested]

largest2PowerMultiplePointSize

public static float largest2PowerMultiplePointSize(Font baseFont,
                                                   String referenceString,
                                                   Dimension2D maxDimension,
                                                   FontRenderContext fontRenderContext)

Returns:

same as largest2PowerPointSize but search is further restricted to sizes that are greater than or equal to baseFont's size

largest2PowerPointSize

public static float largest2PowerPointSize(Font baseFont,
                                           String referenceString,
                                           Dimension2D maxDimension,
                                           FontRenderContext fontRenderContext)

Returns:

same as largestPointSize but search is further restricted to sizes that are an integral power of 2 (half, double, etc.) of baseFont's size [never tested]

largestPointSize

public static float largestPointSize(Font baseFont,
                                     String referenceString,
                                     Dimension2D maxDimension,
                                     FontRenderContext fontRenderContext)

Returns:

largest point size of baseFont that, when used to render referenceString, will allow it to fit within maxDimension [incomplete]
