Method Detail

getPlatform

public static RadianceCommonCortex.Platform getPlatform()

getDefaultFontPolicy

public static FontPolicy getDefaultFontPolicy()

Returns the default platform-specific font policy.

Returns:

Default platform-specific font policy.

getScaledFontPolicy

public static FontPolicy getScaledFontPolicy(float scaleFactor)

Returns scaled platform-specific font policy.

Parameters:

scaleFactor - Scale factor. Should be positive.

Returns:

Scaled platform-specific font policy.

createThumbnail

public static java.awt.image.BufferedImage createThumbnail(double scale,
                                                           java.awt.image.BufferedImage image,
                                                           int requestedThumbWidth)

Creates a thumbnail of the specified width.

Parameters:

image - The original image.

requestedThumbWidth - The width of the resulting thumbnail.

Returns:

Thumbnail of the specified width.

installDesktopHints

public static void installDesktopHints(java.awt.Graphics2D g2,
                                       java.awt.Font font)

clearDesktopHints

public static void clearDesktopHints(java.awt.Graphics2D g2,
                                     java.awt.Font font)

getScaleFactor

public static double getScaleFactor(java.awt.Component component)

getBlankScaledImage

public static java.awt.image.BufferedImage getBlankScaledImage(double scale,
                                                               int width,
                                                               int height)

Gets a scaled, high-DPI aware image of specified dimensions.

Use drawImageWithScale(Graphics, double, Image, int, int) or drawImageWithScale(Graphics, double, Image, int, int, int, int, int, int) to draw the image obtained with this method. Note that applying an extension of RadianceAbstractFilter is a "safe" operation as far as preserving the scale-aware configuration. If you are using a custom BufferedImageOp that is not a RadianceAbstractFilter, the resulting image will be a regular BufferedImage that will not be drawn correctly using one of the drawImageWithScale methods above. In such a case, use getScaleFactor(Component) to divide the image width and height for the purposes of drawing.

Parameters:

width - Width of the target image

height - Width of the target image

Returns:

A scaled, high-DPI aware image of specified dimensions.

getBlankUnscaledImage

public static java.awt.image.BufferedImage getBlankUnscaledImage(int width,
                                                                 int height)

Gets an unscaled, high-DPI aware image of specified dimensions.

Parameters:

width - Width of the target image

height - Width of the target image

Returns:

An unscaled, high-DPI aware image of specified dimensions.
