ComfyUI Node: PDF Page Splitter

PDF Page Splitter:

The PDFPageSplitter node is designed to facilitate the extraction of individual pages from a PDF document, enabling you to work with specific sections of a PDF file without needing to handle the entire document. This node is particularly useful for tasks that require processing or analyzing specific pages, such as extracting text or images from selected pages. By splitting a PDF into its constituent pages, you can streamline workflows and focus on the most relevant parts of a document, enhancing efficiency and precision in your projects.

PDF Page Splitter Input Parameters:

file_path

The file_path parameter specifies the location of the PDF file you wish to split. This should be the full path to the PDF document on your system. The accuracy of this path is crucial as it directly impacts the node's ability to locate and process the file. Ensure that the path is correct and that the file exists at the specified location.

page_numbers

The page_numbers parameter allows you to define which pages of the PDF you want to extract. This should be a comma-separated list of integers representing the page numbers. For example, "1,3,5" would extract pages 1, 3, and 5. The page numbers must be within the range of the document's total pages. Providing invalid page numbers will result in an error.

dpi

The dpi (dots per inch) parameter determines the resolution of the output images for each extracted page. A higher DPI value results in higher resolution images, which can be beneficial for detailed analysis or high-quality outputs. However, higher DPI values also increase processing time and memory usage. The default value is typically set to 72 DPI, but you can adjust this based on your specific needs.

PDF Page Splitter Output Parameters:

images

The images output parameter is a list of tensors, each representing an image of an extracted page from the PDF. These images are in RGB format and normalized to a range of 0.0 to 1.0. Each tensor can be used for further processing, such as image analysis or conversion to other formats. The output provides a convenient way to handle and manipulate the visual content of the selected PDF pages.

PDF Page Splitter Usage Tips:

• Ensure the file_path is accurate and the file exists to avoid file not found errors.
• Use the page_numbers parameter to focus on specific pages, which can save processing time and resources.
• Adjust the dpi parameter based on the required image quality; higher DPI values yield better quality but require more resources.
• Validate the page numbers to ensure they fall within the document's range to prevent errors.

PDF Page Splitter Common Errors and Solutions:

Invalid page numbers. Please provide comma-separated integers.

• Explanation: This error occurs when the page_numbers parameter contains non-integer values or is not properly formatted.
• Solution: Ensure that the page_numbers parameter is a comma-separated list of integers, with no extra spaces or invalid characters.

File not found

• Explanation: This error indicates that the specified file_path does not point to an existing file.
• Solution: Verify that the file_path is correct and that the file exists at the specified location. Double-check the path for any typos or errors.

Selected index is out of range. Available chunks: <number_of_chunks>

• Explanation: This error occurs when the selected_index parameter is outside the range of available chunks.
• Solution: Ensure that the selected_index is within the valid range of chunk indices. Adjust the index to fall within the available range.
