  • Ask HN: What Are You Working On? (February 2025)
    I'm still working on DocSpring [1], originally launched on Hacker News in October 2017 under the name "FormAPI." It's a PDF generation API with a template editor UI for setting up fields on PDF forms. It makes it easy to turn complex tax and immigration forms into simple type-safe APIs with strong validations. I've been having a lot of fun with AI agents lately. Have tried a lot of them - Cline, Roo Code,... - Source: Hacker News / 3 months ago

  • So you want to modify the text of a PDF by hand
    Great post. I've spend a lot of time reading through the PDF specification over the last ~5 years while building DocSpring [1], and I still feel like I've barely scratched the surface. Qpdf is a great tool. One of my other favorites is RUPS [2], which really lets you dig into the structure of a PDF.

  • PDF Generation, Bloat and Optimization
    WKHTMLTOPDF (LGPLv3; portable) tends to be faster and generate smaller PDFs. It can also run concurrently and generate PDFs in the background without using a ColdFusion thread or impacting the Java heap memory. Download. - Source: dev.to / about 2 months ago
  • Hack WKHTMLTOPDF PDF to enable Adobe Acrobat Field Editing
    I recently integrated the auto-generation of survey results into a downloadable PDF using ColdFusion and WKHTMLTOPDF 0.12.6. Our client provided a pre-generated PDF cover page with some editable fields that we prepended to the PDF using PDFtk. Unfortunately, all auto-generated bookmarks became unusable after cover page is prepended. - Source: dev.to / 8 months ago
  • Embed a Full HTML Document Inline Using Shadow DOM
    We use ColdFusion/CFML to generate valid HTML documents for PDF generation using jsoup & WKHTMLTOPDF. If the generated HTML content is simply outputted onto an existing webpage, the webpage becomes invalid (due to double DOCTYPE "inception") and the website's global CSS styles will polluting the preview. - Source: dev.to / 9 months ago
