Description
Parse content stream
- parseContentStream :: MonadIO m => RIS -> [StreamFilter] -> (Ref -> IS -> IO IS) -> [(Stream Int64, Ref, Int)] -> PdfE m (InputStream Expr)
- readNextOperator :: MonadIO m => InputStream Expr -> PdfE m (Maybe Operator)
- parseContent :: Parser (Maybe Expr)
Documentation
Arguments
| :: MonadIO m | |
| => RIS | random input stream to read data from |
| -> [StreamFilter] | how to unpack data |
| -> (Ref -> IS -> IO IS) | how to decrypt data |
| -> [(Stream Int64, Ref, Int)] | content streams (with offset), their refs and length |
| -> PdfE m (InputStream Expr) |
Parse content streams for a page
Note: we need content stream ref to be able to decrypt stream content. We need stream length because it can be an indirect object in stream dictionary
readNextOperator :: MonadIO m => InputStream Expr -> PdfE m (Maybe Operator) Source
Read the next operator if any
parseContent :: Parser (Maybe Expr) Source
