Attention: * :meth:`~.PdfDocument.init_forms` must have been called on the parent pdf, before the page was retrieved, for this method to work. In other words, :attr:`.PdfPage.formenv` must be non-null. * Flattening may invalidate existing handles to the page, so you'll want to re-initialize these afterwards. Parameters: flag (int): PDFium flattening target (:attr:`FLAT_*`) Returns: int: PDFium flattening status (:attr:`FLATTEN_*`). :attr:`FLATTEN_FAIL` is handled internally. zFpage.flatten() requires prior pdf.init_forms(), before page retrieval.z,Failed to flatten annotations / form fields.)r RuntimeErrorrFPDFPage_Flatten FLATTEN_FAILr)rflagrcs rflattenzPdfPage.flattenHsR| ighh h  &tT 2 2 & & &LMM M rr)rrrrFc tj|z} tj|z} |dvr| | } } fd|D}| |dz |dz } | |dz |dz } t d| | fDrt dt |fi|\} }}}||r|tjz}|| | | | }| |dd| | |d |d | | tj |f}||g||R}|tj |ntj d }tj|d t||}tjg|||R}|tjks Jd tj||r|jrtj|jg|Rt-j||f|_|S)a Rasterize the page to a :class:`.PdfBitmap`. Parameters: scale (float): A factor scaling the number of pixels per PDF canvas unit. This defines the resolution of the image. To convert a DPI value to a scale factor, multiply it by the size of 1 canvas unit in inches (usually 1/72in). [#user_unit]_ rotation (int): Additional rotation in degrees (0, 90, 180, or 270). crop (tuple[float, float, float, float]): Amount to cut off from view (left, bottom, right, top), in PDF canvas units. Rendering crop applies on bitmap level (i.e. after rotation), unlike changing the page cropbox using :meth:`.set_cropbox`. Negative crop is not supported (though no exception will be raised). It may produce a larger canvas but not actually expand the rendering area, as of PDFium 7825. may_draw_forms (bool): If True, render form fields (provided the document has forms and :meth:`~.PdfDocument.init_forms` was called). bitmap_maker (typing.Callable): Callback function used to create the :class:`.PdfBitmap`. fill_color (tuple[int, int, int, int]): Color the bitmap will be filled with before rendering. This uses RGBA syntax regardless of the pixel format used, with values from 0 to 255. If the fill color is not opaque (i.e. has transparency), ``{BGR,RGB}A`` will be used. grayscale (bool): If True, render in grayscale mode. optimize_mode (None | str): Page rendering optimization mode (None, "lcd", "print"). draw_annots (bool): If True, render page annotations. no_smoothtext (bool): If True, disable text anti-aliasing. Overrides ``optimize_mode="lcd"``. no_smoothimage (bool): If True, disable image anti-aliasing. no_smoothpath (bool): If True, disable path anti-aliasing. force_halftone (bool): If True, always use halftone for image stretching. limit_image_cache (bool): If True, limit image cache size. rev_byteorder (bool): If True, render with reverse byte order, leading to ``RGB{A/x}`` output rather than ``BGR{A/x}``. Other pixel formats are not affected. prefer_bgrx (bool): If True, use 4-byte ``{BGR/RGB}x`` rather than 3-byte ``{BGR/RGB}`` (i.e. add an unused byte). Other pixel formats are not affected. maybe_alpha (bool): If True, use a pixel format with alpha channel (i.e. ``{BGR/RGB}A``) if page content has transparency. This is recommended for performance in these cases, but as page-dependent format selection can be unexpected, it is not enabled by default. force_bitmap_format (int | None): If given, override automatic pixel format selection and enforce use of the given format (one of the :attr:`FPDFBitmap_*` constants). In this case, you should not pass any other format selection options, except potentially *rev_byteorder*. extra_flags (int): Additional PDFium rendering flags. May be combined with bitwise OR (``|`` operator). color_scheme (PdfColorScheme | None): A custom pdfium color scheme. Note that this may flatten different colors into one, so the usability of this is limited. fill_to_stroke (bool): If a *color_scheme* is given, whether to only draw borders around fill areas using the `path_stroke` color, instead of filling with the `path_fill` color. Returns: PdfBitmap: Bitmap of the rendered page. .. admonition:: Format selection This is the format selection hierarchy used by :meth:`.render`, from lowest to highest priority: * default: ``BGR`` * ``prefer_bgrx=True``: ``BGRx`` * ``grayscale=True``: ``L`` * ``maybe_alpha=True``: ``BGRA`` if the page has transparency, else the format selected otherwise * ``fill_color[3] < 255``: ``BGRA`` (background color with transparency) * ``force_bitmap_format=...`` -> any supported by pdfium Additionally, ``rev_byteorder=True`` will swap ``BGR{A/x}`` to ``RGB{A/x}`` if applicable. .. [#user_unit] Since PDF 1.6, pages may define an additional user unit factor. In this case, 1 canvas unit is equivalent to ``user_unit * (1/72)`` inches. PDFium does not currently provide an API to get the user unit, so this is not taken into account. )Zic>g|]}tj|zSr@)mathceil).0cscales r z"PdfPage.render..s'111q !E'""111rrrc3"K|] }|dkV dS)rNr@)rds r z!PdfPage.render..s&..q1u......rzCrop exceeds page dimensionsN)format rev_byteorder)versionNeedToPauseNowz0Progressive render return code indicates failure)rrr r#anyrt_parse_renderoptsrFPDF_CONVERT_FILL_TO_STROKE fill_rectr)r/FPDF_RenderPageBitmap IFSDK_PAUSE set_callback _pause_noopconvert*FPDF_RenderPageBitmapWithColorScheme_StartFPDF_RENDER_FAILEDFPDF_RenderPage_Closer FPDF_FFLDrawweakrefref _render_args)rrr0cropmay_draw_forms bitmap_maker color_schemefill_to_strokekwargs src_width src_heightwidthheight cl_formatr fill_colorflagsbitmappos_args render_argspausefpdf_csstatuss ` rrenderzPdfPage.renderbsaRYt~~//5899 Yt005899 y $. zI1111D111d1g%Q/d1g%Q/ ..ufo... . . =;<< <6G6W6WPV6W6W3 =*e  $. $ X9 9EeVI][[[Q5&999!WHtAwh :x?WX`?abt6h666    *K 8 8 8(333E  !%)9; G G G"**=99GHf+fW^f`efffFX8888:l888  *4 0 0 0  >dl >  !$, = = = = =&{400(; r)T)NrNrN)&__name__ __module__ __qualname____doc__r staticmethodrpropertyrr r#r%r,r1r=rDrLrPrSrWrZr]r`rcrfrkrqrzrrrrFLAT_NORMALDISPLAYrr new_nativer __classcell__)rs@rrrsQ  <<<<<%%\% X111222555888PPPBBB c c c c888 [[[[777 [[[[888 ZZZZ777 YYYY666 > > >   4$$$BBBB3333l$68!$/"LLLLLLLLrrc|ddks|r tj|r tjS|r tjS|r tjStjS)Nr)rFPDFPage_HasTransparencyFPDFBitmap_BGRAFPDFBitmap_GrayFPDFBitmap_BGRxFPDFBitmap_BGR)rsr grayscale prefer_bgrx maybe_alphas r_auto_bitmap_formatrs]!}s{x/PQU/V/V'' ''' '''&&rrrrrFTc| t|||| | }n| }|tjkrd} |}|r|tjz}|r|tjz}|r|tjz}|r|tjz}|r|tjz}|r|tjz}| r|tj z}| r|tj z}|rR| }|dkr|tj z}n(|dkr|tj z}ntd||| ||fS)NFlcdprintzInvalid optimize_mode )rrrFPDF_GRAYSCALE FPDF_ANNOTFPDF_RENDER_NO_SMOOTHTEXTFPDF_RENDER_NO_SMOOTHIMAGEFPDF_RENDER_NO_SMOOTHPATHFPDF_RENDER_FORCEHALFTONEFPDF_RENDER_LIMITEDIMAGECACHEFPDF_REVERSE_BYTE_ORDERlower FPDF_LCD_TEXT FPDF_PRINTINGrt)rsrr optimize_mode draw_annots no_smoothtextno_smoothimage no_smoothpathforce_halftonelimit_image_cacherrrforce_bitmap_format extra_flagsrrs rrrs]$"'j)[R]^^ ' H,,, E) ((% $$4 335 444 334 338 772 11G%++-- E ! !
