Core Functionality

The VeryPDF TIFF To PDF ActiveX DLL stands out for its robust and varied functionality, catering to a wide range of document and image processing needs:

  • PDF to TIFF Conversion: This feature allows for the conversion of PDF documents into TIFF files, supporting both single-page and multi-page outputs. This is especially useful for applications that need to convert PDFs for archival purposes or for processing in image-based systems.
  • TIFF to PDF Conversion: Conversely, the DLL enables the conversion of TIFF files—whether single or multiple pages—into a PDF document. This feature is invaluable for creating standardized PDF documents from scanned images or other TIFF sources.
  • PDF to Image Conversion: This tool lets developers convert PDF documents into various image formats, including BMP, JPEG, WMF, EMF, EPS, PNG, and GIF. It’s particularly useful for applications that need to extract visual data from PDFs or generate image previews.
  • Image Format Conversion: Beyond PDF-related conversions, this DLL also supports the conversion of various image formats into TIFF files, offering flexibility in handling image data within your application.

Development and Integration

The ActiveX DLL is designed with developers in mind, providing support for a broad array of programming languages and development environments:

  • Supported Languages: It works seamlessly with VB Script, JavaScript, Perl, PHP, Python, ASP, ASP.Net, VB.Net, C#, VB6, ColdFusion, Delphi, VC++, and Java. This wide-ranging support ensures that developers can easily integrate the DLL into their existing projects, regardless of the programming language they are using.
  • Sample Code and Documentation: The DLL comes with comprehensive documentation and example code to help developers get started quickly. Whether you're converting a TIFF file to PDF, generating an image from a PDF, or performing any other supported task, the provided sample code makes it easier to understand and implement these features.

Licensing and Deployment

One of the key benefits of the VeryPDF TIFF To PDF ActiveX DLL is its royalty-free licensing. This means that once you purchase the DLL, you can integrate it into your applications without any additional fees, regardless of how many copies or instances of your application are distributed.

  • Royalty-Free Use: This is especially advantageous for developers and companies who need to deploy their applications on a large scale. You can incorporate the DLL into multiple applications and distribute them to end users without worrying about incurring additional costs.
  • No Limits on Distribution: There are no restrictions on the number of applications or the scale of distribution. This flexibility is ideal for software companies and developers who aim to deploy their solutions widely across different user bases or environments.

Advanced Features and Flexibility

The VeryPDF TIFF To PDF ActiveX DLL offers advanced features that provide flexibility and control over the conversion process:

  • Customizable Output Options: When converting files, you can specify various output options, such as DPI settings for images and different color depths for TIFF files (e.g., 24-bit RGB or 1-bit G4 TIFF). This allows you to tailor the conversion process to meet specific requirements, whether you need high-resolution images for printing or compressed formats for online use.
  • Page Range Selection: For PDF conversions, you can specify particular page ranges to convert, giving you control over which parts of a document are processed. This feature is particularly useful for large documents where only specific sections need to be converted.
  • Error Handling: The DLL returns detailed error codes for different failure scenarios, such as when source files do not exist or cannot be opened. This makes it easier to troubleshoot issues during the development and deployment phases.
  • Password-Protected PDFs: The DLL supports the conversion of password-protected PDFs, making it suitable for applications that deal with secured documents. Developers can pass the necessary password to unlock and process these files programmatically.
