Attention: * :meth:`~.PdfDocument.init_forms` must have been called on the parent pdf, before the page was retrieved, for this method to work.

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 in PDF canvas units to cut off from page borders (left, bottom, right, top). Crop is applied after rotation. 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* 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. )Zicsg|] }t|qSr)mathceil).0cscalerr sz"PdfPage.render..rrNcss|]}|dkVqdS)rNNr)r]drrr sz!PdfPage.render..zCrop exceeds page dimensionsN)format rev_byteorder)versionZNeedToPauseNowcSr,)NFr)_rrrr-r.z PdfPage.render..)r[r\rranyrF_parse_renderoptsrZFPDF_CONVERT_FILL_TO_STROKEZ fill_rectrrZFPDF_RenderPageBitmapZ IFSDK_PAUSEZ set_callbackconvertZ*FPDF_RenderPageBitmapWithColorScheme_StartZFPDF_RENDER_DONEZFPDF_RenderPage_Closer Z FPDF_FFLDrawweakrefrefZ _pos_args)rr`r cropZmay_draw_formsZ bitmap_makerZ color_schemeZfill_to_strokekwargsZ src_widthZ src_heightwidthheight cl_formatrg fill_colorflagsZbitmapZpos_argsZ render_argspausefpdf_csstatusrr_rrenderXs8g         zPdfPage.render)T)NrMNr)&__name__ __module__ __qualname____doc__r staticmethodrpropertyrrrrrr!r+r0r7r9r;r<r=r>r?r@rArCrDrHrKrLrTrZFLAT_NORMALDISPLAYrYrZ new_nativery __classcell__rrrrrsL          ! 1rcCs:|ddks |rt|rtjS|rtjS|rtjStjS)Nrc)rZFPDFPage_HasTransparencyZFPDFBitmap_BGRAFPDFBitmap_GrayZFPDFBitmap_BGRxZFPDFBitmap_BGR)rErt grayscale prefer_bgrx maybe_alpharrr_auto_bitmap_formatsrrrrrFTcCs| dur t|||| | }n| }|tjkrd} |}|r|tjO}|r&|tjO}|r-|tjO}|r4|tjO}|r;|tjO}|rB|tjO}| rI|tj O}| rP|tj O}|rq| }|dkr`|tj O}n|dkrj|tj O}ntd||| ||fS)NFZlcdprintzInvalid optimize_mode )rrrZFPDF_GRAYSCALEZ FPDF_ANNOTZFPDF_RENDER_NO_SMOOTHTEXTZFPDF_RENDER_NO_SMOOTHIMAGEZFPDF_RENDER_NO_SMOOTHPATHZFPDF_RENDER_FORCEHALFTONEZFPDF_RENDER_LIMITEDIMAGECACHEZFPDF_REVERSE_BYTE_ORDERlowerZ FPDF_LCD_TEXTZ FPDF_PRINTINGrF)rErtrZ optimize_modeZ draw_annotsZ no_smoothtextZno_smoothimageZ no_smoothpathZforce_halftoneZlimit_image_cachergrrZforce_bitmap_format extra_flagsrsrurrrrks<            rkc@s(eZdZdZddZddZddZdS) rz Rendering color scheme.
