• Implementing pymupdf solutions
• Debugging pymupdf code
• Learning pymupdf best practices

Quick Reference

Common Patterns

Pattern 1: The name identifying the colorspace. Example: pymupdf.csCMYK.name = ‘DeviceCMYK’.

csRGB

Pattern 2: Added a method paper_rect() which returns a Rect for a supplied paper format string. Example: fitz.paper_rect(“letter”) = fitz.Rect(0.0, 0.0, 612.0, 792.0).

paper_rect()

Pattern 3: Example:

bottom-left -> top-left

Pattern 4: A typical use of this attribute would be setting Page.cropbox_position to this value, when you are creating shapes for later or external use. If you have not manipulated the attribute yourself, it should reflect a rectangle that contains all drawings so far.

Page.cropbox_position

Pattern 5: With Document.insert_file() you can invoke the method to merge supported files with PDF. For example:

Document.insert_file()

Pattern 6: Example:

Page.cropbox_position()

Pattern 7: pix is a Pixmap object which (in this case) contains an RGB image of the page, ready to be used for many purposes. Method Page.get_pixmap() offers lots of variations for controlling the image: resolution / DPI, colorspace (e.g. to produce a grayscale image or an image with a subtractive color scheme), transparency, rotation, mirroring, shifting, shearing, etc. For example: to create an RGBA image (i.e. containing an alpha channel), specify pix = page.get_pixmap(alpha=True).

Pattern 8: Please see the Stories recipes for a number of typical use cases.

Document.convert_to_pdf()
