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. ### setDoPaletteCorrection(boolean value) {#setDoPaletteCorrection-boolean} ```java public void setDoPaletteCorrection(boolean value) ``` Gets or sets a value indicating whether palette correction is applied. **Parameters:** | Parameter | Type | Description | | --- | --- | --- | | value | boolean | 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. | ### getColorResolution() {#getColorResolution} ```java public byte getColorResolution() ``` Gets or sets the GIF color resolution. **Returns:** byte - The 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. ### setColorResolution(byte value) {#setColorResolution-byte} ```java public void setColorResolution(byte value) ``` Gets or sets the GIF color resolution. **Parameters:** | Parameter | Type | Description | | --- | --- | --- | | value | byte | The 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. | ### isPaletteSorted() {#isPaletteSorted} ```java public boolean isPaletteSorted() ``` Gets or sets a value indicating whether palette entries are sorted. **Returns:** boolean - true if palette entries are sorted; otherwise, false . ### setPaletteSorted(boolean value) {#setPaletteSorted-boolean} ```java public void setPaletteSorted(boolean value) ``` Gets or sets a value indicating whether palette entries are sorted. **Parameters:** | Parameter | Type | Description | | --- | --- | --- | | value | boolean | true if palette entries are sorted; otherwise, false . | ### getPixelAspectRatio() {#getPixelAspectRatio} ```java public byte getPixelAspectRatio() ``` Gets or sets the GIF pixel aspect ratio. **Returns:** byte - 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. ### setPixelAspectRatio(byte value) {#setPixelAspectRatio-byte} ```java public void setPixelAspectRatio(byte value) ``` Gets or sets the GIF pixel aspect ratio. **Parameters:** | Parameter | Type | Description | | --- | --- | --- | | value | byte | 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. | ### getBackgroundColorIndex() {#getBackgroundColorIndex} ```java public byte getBackgroundColorIndex() ``` Gets or sets the GIF background color index. **Returns:** byte - The GIF background color index. ### setBackgroundColorIndex(byte value) {#setBackgroundColorIndex-byte} ```java public void setBackgroundColorIndex(byte value) ``` Gets or sets the GIF background color index. **Parameters:** | Parameter | Type | Description | | --- | --- | --- | | value | byte | The GIF background color index. | ### hasTrailer() {#hasTrailer} ```java public boolean hasTrailer() ``` Gets or sets a value indicating whether GIF has trailer. **Returns:** boolean - true if GIF has trailer; otherwise, false . ### setTrailer(boolean value) {#setTrailer-boolean} ```java public void setTrailer(boolean value) ``` Gets or sets a value indicating whether GIF has trailer. **Parameters:** | Parameter | Type | Description | | --- | --- | --- | | value | boolean | true if GIF has trailer; otherwise, false . | ### getInterlaced() {#getInterlaced} ```java public boolean getInterlaced() ``` True if image should be interlaced. **Returns:** boolean ### setInterlaced(boolean value) {#setInterlaced-boolean} ```java public void setInterlaced(boolean value) ``` True if image should be interlaced.
