FLMASK can accommodate the following 5 types of masking methods.

Please carefully study and learn their advantages and disadvantages in order to select the proper mask method to best meet your needs.

Mask Type	256-Color Image	JPEG Format	Multiplex Masking	Concealing Ability	Disadvantages
Q0 MASK	NG	Good	NG	Poor	Too many options, no uniformity
WIN MASK	Good	Poor	NG	Poor	Mask Noise occurs with JPEG file
MEKO MASK	NG	Good	Good	Poor	Difficult to mask small area
FL MASK	Good	Good	Good	Good	Difficult to mask small area
CP MASK	NG	Good	Good	Excellent	cannot treat 256-color

* Multiplex Mask (Multi-mask) is masking over part or all of an area already masked.
* Q0 MASK in this case is with Negative-Positive exchange plus Glassy Effect.

	Original Image Following are examples of different mask treatments as applied to original JPEG image at left.
	Q0 MASK "Q0 Mask" is a well-known full-color image masking method developed by Mr."Kurakura" and used in his masking tool "Q0MASK". So called "Glassy Effects" and "negative-positive exchange" are characteristic. Q0 Mask has several options, and combination of these options make a variety of effects possible. However, because of this variety, it is difficult to maintain uniformity. Full-Color Image ONLY
	CP MASK This mask process originated with Mr.Uchino (an author of Mozkiller for Macintosh), and was developed jointly with the author of FLMASK. In the masking process, a string named "Coded Pattern(CP)" is used for various masking patterns. In other words, Coded Patterns and masking patterns have a one-to-one correspondence. This mask has no options, and a uniform masking method makes this process user friendly. Full-Color Image Only The image at left is an example of this mask.
	FL MASK This is a newly developed masking method especially designed for FLMASK. Its characteristic is that of masked areas with a whirlpool pattern. This mask has no options. A uniform masking method makes this process user friendly. (There are, however, some options to make it compatible with older FLMASK versions.) FL Mask supports both full- and 256-color images. The old version does not have Negative-Positive exchange function.
	WIN MASK "WIN Mask" is a well known 256-color image masking method employed in Mr. Takaaki Tomura's "WinMask". This mask is characterized by vertical stripes. Since WIN Mask has no options, it is very easy to mask 256-color images. Please note that an unmasked image will have Mask Noise if an image processed with WIN Mask is saved as JPEG file.
	MEKO MASK "MEKO Mask" is a well-known full-color image masking method employed in Mr. Yoji Igarashi's "MekoMask". This mask exchanges blocked areas randomly. This mask has no options, and has a uniform masking method. Full-Color Image ONLY
