 ### `get_images` shows no images but I can clearly see charts in the PDF. Why?
 
-Charts and diagrams created by tools like matplotlib, Excel, or R are typically rendered as vector graphics (PDF drawing commands), not raster images. `get_images ` only lists embedded raster image objects and will not detect vector graphics. To capture these, rasterise the entire page with `page.get_pixmap()`.

 ### How does OCR work in PyMuPDF? Does it require a separate Tesseract installation?
 
-PyMuPDF uses Tesseract for OCR, but Tesseract's C++ code is compiled directly into MuPDF — it is not called as an external subprocess. The only external requirement is the **Tesseract language data files** (`tessdata`). Over 100 languages are supported. There is no Python-level pytesseract dependency.
+PyMuPDF uses MuPDF's built-in Tesseract-based OCR support, so there is no Python-level `pytesseract` dependency. However, PyMuPDF still needs access to the **Tesseract language data files** (`tessdata`), and automatic tessdata discovery may invoke the `tesseract` executable (for example, to list available languages) if you do not explicitly provide a tessdata path. In practice, the recommended setup is to either install Tesseract so discovery works automatically, or configure the tessdata location yourself via the `tessdata` parameter or the `TESSDATA_PREFIX` environment variable. Over 100 languages are supported.
