Enum Constant Detail

LOSSLESS_COMPRESSION

public static final PdfOptimizerProfile LOSSLESS_COMPRESSION

Lossless compression profile. Includes:

• stream compression optimization (done by CompressionOptimizer);
• font duplication optimization (done by FontDuplicationOptimizer);
• font subsetting optimization (done by FontSubsettingOptimizer).

LOW_COMPRESSION

public static final PdfOptimizerProfile LOW_COMPRESSION

Low-level compression profile. Includes:

• stream compression optimization (done by CompressionOptimizer);
• font duplication optimization (done by FontDuplicationOptimizer);
• font subsetting optimization (done by FontSubsettingOptimizer);
• image quality optimization (done by ImageQualityOptimizer): bitmap images are scaled with coefficient 0.8; images in RGB and Grey color space, both scaled bitmaps and originally jpeg images, are compressed by JPEG compression with coefficient 0.8.

MID_COMPRESSION

public static final PdfOptimizerProfile MID_COMPRESSION

Mid-level compression profile. Includes:

• stream compression optimization (done by CompressionOptimizer);
• font duplication optimization (done by FontDuplicationOptimizer);
• font subsetting optimization (done by FontSubsettingOptimizer);
• image quality optimization (done by ImageQualityOptimizer): bitmap images are scaled with coefficient 0.5; images in RGB and Grey color space, both scaled bitmaps and originally jpeg images, are compressed by JPEG compression with coefficient 0.5.

HIGH_COMPRESSION

public static final PdfOptimizerProfile HIGH_COMPRESSION

High-level compression profile. Includes:

• stream compression optimization (done by CompressionOptimizer);
• font duplication optimization (done by FontDuplicationOptimizer);
• font subsetting optimization (done by FontSubsettingOptimizer);
• image quality optimization (done by ImageQualityOptimizer): bitmap images are scaled with coefficient 0.15; scaled bitmap images in CMYK color space are converted into images in RGB color space; images in RGB and Grey color space, both scaled bitmaps and originally jpeg images, are compressed by JPEG compression with coefficient 0.15.

CUSTOM

public static final PdfOptimizerProfile CUSTOM

Marker for a custom profile which is empty by default.

Method Detail

values

public static PdfOptimizerProfile[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (PdfOptimizerProfile c : PdfOptimizerProfile.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static PdfOptimizerProfile valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
