Enum InlineImageFilter 

pub enum InlineImageFilter {
    Raw,
    DctDecode,
    JpxDecode,
    Jbig2Decode,
    CcittFaxDecode,
}

Terminal codec filter declared by an inline image’s /F entry.

Marks how a downstream decoder should interpret the PdfInlineImage::data byte payload. Raw means the payload is the literal pixel byte sequence at the declared bit-depth (no terminal codec filter — the dictionary may or may not list a non-codec filter like /Fl in the chain, but those are peeled before the payload reaches the caller).

Variants

Raw

No terminal codec filter — payload is raw pixel bytes. Real PDFs use this most often for small inline images.

DctDecode

/DCTDecode (/DCT) — payload is a JPEG-1 / JFIF stream ready for a JPEG decoder, exactly the same shape the round-23 XObject walker surfaces.

JpxDecode

/JPXDecode (/JPX) — payload is a JPEG 2000 codestream.

Jbig2Decode

/JBIG2Decode (/JBIG2) — payload is a JBIG2 codestream.

CcittFaxDecode

/CCITTFaxDecode (/CCF) — payload is a CCITT T.4 / T.6 fax-encoded stream. (/DecodeParms carries the per-stream /K / /Columns / /Rows parameters; round 35 surfaces the raw bytes only.)

Trait Implementations

impl Clone for InlineImageFilter

fn clone(&self) -> InlineImageFilter

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for InlineImageFilter

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for InlineImageFilter

impl PartialEq for InlineImageFilter

fn eq(&self, other: &InlineImageFilter) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
