if set , grayscale images with a bit depth less than 8 1 , 2 , or 4 will be output in 8 bit form . the output values will occupy the full 8-bit range . for example , gray values 0 , 1 , 2 , and 3 of a 2-bit image will be output as 0 , 85 , 170 , and 255 . the decoding of non-grayscale images and grayscale images with a bit depth of 8 or 16 are unaffected by this setting . the default is not to perform expansion . grayscale images with a depth of 1 , 2 , or 4 bits will be represented using a multipixelpackedsamplemodel and an indexcolormodel . concode_field_sep boolean suppressAlpha concode_elem_sep boolean expandPalette concode_elem_sep boolean performGammaCorrection concode_elem_sep PNGEncodeParam encodeParam concode_elem_sep boolean expandGrayAlpha concode_elem_sep boolean generateEncodeParam concode_elem_sep boolean output8BitGray concode_elem_sep float userExponent concode_elem_sep float displayExponent concode_field_sep void setDisplayExponent concode_elem_sep void setPerformGammaCorrection concode_elem_sep void setEncodeParam concode_elem_sep void setExpandGrayAlpha concode_elem_sep float getUserExponent concode_elem_sep float getDisplayExponent concode_elem_sep boolean getSuppressAlpha concode_elem_sep boolean getPerformGammaCorrection concode_elem_sep void setSuppressAlpha concode_elem_sep boolean getExpandGrayAlpha concode_elem_sep void setGenerateEncodeParam concode_elem_sep PNGEncodeParam getEncodeParam concode_elem_sep void setExpandPalette concode_elem_sep void setUserExponent concode_elem_sep boolean getExpandPalette concode_elem_sep boolean getOutput8BitGray concode_elem_sep boolean getGenerateEncodeParam
