Output
Binary
The node outputs the resulting PDF file as binary data, stored in a configurable binary property (default 'data').
JSON
success- Indicates if the operation was successful (only for merge operation).pages- Number of pages in the generated or merged PDF.size- Size of the generated or merged PDF in bytes.processingTime- Time taken to process the PDF conversion or merge.totalInputFiles- Number of input PDF files merged (only for merge operation).mergedFiles- Array of metadata about each merged file, including file names (only for merge operation).conversionType- The type of conversion performed.metadata- Metadata about the generated PDF, such as page count and size.error- Error message if the conversion or merge failed.
Dependencies
- Requires PDF conversion and merging libraries provided by Dante PDF converters.
- May require network access for fetching content from URLs (HTML to PDF or merging PDFs from URLs).
Troubleshooting
- Error if fewer than two PDFs are provided for merging: Ensure at least two PDF files are supplied when using the merge operation.
- Unsupported input source error: URL input source is only supported for HTML to PDF conversion.
- Error if no PDF files found in binary data for merging: Verify the binary data contains valid PDF files.
- Error if no image files found in binary data for image to PDF conversion: Verify the binary data contains valid image files.
- Conversion failure errors: Check the input content and options for correctness, and ensure the node has necessary permissions and dependencies installed.
