    In This Topic
    Specifies the compression scheme used to compress image or raster data in the output file.
    Syntax
    Members
    MemberDescription
    Adaptive Automatically selects the best compression type for each image on the page. JPEG will be used for large images with many unique colors. DEFLATE will be used for all other images.
    Deflate A lossless data compression.
    JPEG A lossy data compression.
    JPEG2000 A lossy data compression.
    LZW Lempel-Ziv-Welch, a lossless data compression.
    None No compression.
    RLE Run-length encoded compression.
