Hint: This class provides built-in converters (e. g. :meth:`.to_pil`, :meth:`.to_numpy`) that may be used to create a different representation of the bitmap. Converters can be applied on :class:`.PdfBitmap` objects either as bound method (``bitmap.to_*()``), or as function (``PdfBitmap.to_*(bitmap)``) The second pattern is useful for API methods that need to apply a caller-provided converter (e. g. :meth:`.PdfDocument.render`) .. _PIL Modes: https://pillow.readthedocs.io/en/stable/handbook/concepts.html#concept-modes Note: All attributes of :class:`.PdfBitmapInfo` are available in this class as well. Warning: ``bitmap.close()``, which frees the buffer of foreign bitmaps, is not validated for safety. A bitmap must not be closed when other objects still depend on its buffer! Attributes: raw (FPDF_BITMAP): The underlying PDFium bitmap handle. buffer (~ctypes.c_ubyte): A ctypes array representation of the pixel data (each item is an unsigned byte, i. e. a number ranging from 0 to 255). c n||||f\|_|_|_|_|||c|_|_|_tj|j|_ |jr tj n tj |j|_ ttj||jdS)N) needs_freeobj)rawbufferwidthheightstrideformat rev_byteorderpdfium_iBitmapTypeToNChannels n_channelsBitmapTypeToStrReverseBitmapTypeToStrmodesuper__init__pdfium_cFPDFBitmap_Destroy) selfr r r rrrrr __class__s W/var/www/html/mpstechhub/venv/lib/python3.11/site-packages/pypdfium2/_helpers/bitmap.pyrzPdfBitmap.__init__4s9n8;;F*5&&&&QQ||C777rc|r|tj|znd}tj|||d|}|||S)z Create a new bitmap using :func:`FPDFBitmap_CreateEx`, with a buffer allocated by PDFium.

The array contains as many rows as the bitmap is high. Each row contains as many pixels as the bitmap is wide. The length of each pixel corresponds to the number of channels. The resulting array is supposed to share memory with the original bitmap buffer, so changes to the buffer should be reflected in the array, and vice versa.

For ``RGBA``, ``RGBX`` and ``L`` buffers, PIL is supposed to share memory with the original bitmap buffer, so changes to the buffer should be reflected in the image, and vice versa.

Due to the restricted number of color formats and bit depths supported by PDFium's bitmap implementation, this may be a lossy operation. Bitmaps returned by this function should be treated as immutable (i.e. don't call :meth:`.fill_rect`). Parameters: pil_image (PIL.Image.Image): The image. Returns: PdfBitmap: PDFium bitmap (with a copy of the PIL image's data). .. deprecated:: 4.25 The *recopy* parameter has been deprecated.
