Gets or sets a value indicating whether palette correction is applied.
true if palette correction is applied; otherwise, false.
Palette correction means that whenever image is exported to GIF the source image colors will be analyzed in order to build the best matching palette (in case image Palette does not exist or not specified in the options). The analyze process takes some time however the output image will have the best matching color palette and result is visually better.
byte getColorResolution()
Gets or sets the GIF color resolution.
Color Resolution - Number of bits per primary color available to the original image, minus 1. This value represents the size of the entire palette from which the colors in the graphic were selected, not the number of colors actually used in the graphic. For example, if the value in this field is 3, then the palette of the original image had 4 bits per primary color available to create the image. This value should be set to indicate the richness of the original palette, even if not every color from the whole palette is available on the source machine.
boolean isPaletteSorted()
Gets or sets a value indicating whether palette entries are sorted.
true if palette entries are sorted; otherwise, false.byte getPixelAspectRatio()
Gets or sets the GIF pixel aspect ratio.
Pixel Aspect Ratio - Factor used to compute an approximation of the aspect ratio of the pixel in the original image. If the value of the field is not 0, this approximation of the aspect ratio is computed based on the formula: Aspect Ratio = (Pixel Aspect Ratio + 15) / 64 The Pixel Aspect Ratio is defined to be the quotient of the pixel's width over its height. The value range in this field allows specification of the widest pixel of 4:1 to the tallest pixel of 1:4 in increments of 1/64th. Values : 0 - No aspect ratio information is given. 1..255 - Value used in the computation.
byte getBackgroundColorIndex()
Gets or sets the GIF background color index.
boolean hasTrailer()
Gets or sets a value indicating whether GIF has trailer.
true if GIF has trailer; otherwise, false.boolean getInterlaced()
True if image should be interlaced.
int getMaxDiff()
Gets or sets the maximum allowed pixel difference. If greater than zero, lossy compression will be used. Recommended value for optimal lossy compression is 80. 30 is very light compression, 200 is heavy. It works best when only little loss is introduced, and due to limitation of the compression algorithm very high loss levels won't give as much gain. The range of allowed values is [0, 1000].
