Convert PDF to FTS

Understanding PDF and FTS file formats

PDF (Portable Document Format) is a widely used file format developed by Adobe for presenting documents in a manner independent of application software, hardware, and operating systems. PDFs can contain text, images, vector graphics, and more, making them ideal for document sharing and printing.

FTS (Flexible Image Transport System) is a digital file format commonly used in astronomy for storing, transmitting, and processing scientific and image data. FTS, also known as FITS, is designed to store multidimensional arrays (such as images) and tables, and is the standard data format in astronomy.

Why convert PDF to FTS?

Converting a PDF to FTS is useful when you need to use document images or graphics from a PDF in astronomical data analysis or visualization tools that require the FTS format. This is especially relevant for researchers who want to annotate, analyze, or process images from scientific papers or reports in astronomy software.

How to convert PDF to FTS

There is no direct one-step converter from PDF to FTS, as these formats serve very different purposes. However, you can achieve the conversion by following these steps:

1. Extract images from the PDF: Use a PDF viewer or editor to export the desired page or image as a standard image format (such as TIFF or PNG). For example, in Adobe Acrobat, use File → Export To → Image → TIFF.
2. Convert the image to FTS: Use astronomical image processing software to convert the extracted image to FTS format.

Recommended software for PDF to FTS conversion

• Adobe Acrobat: For extracting images from PDF files. Use File → Export To → Image to save pages or images as TIFF or PNG.
• GIMP: Open the exported image and use the File → Export As option to save as FITS/FTS (requires the FITS plugin).
• SAOImage DS9: A popular astronomical imaging tool that can import standard image formats and save them as FTS.
• IRAF: Advanced users can use IRAF tasks to convert standard images to FTS format.

Step-by-step example using GIMP

1. Extract the image from your PDF using Adobe Acrobat or another PDF tool.
2. Open the image in GIMP.
3. Go to File → Export As and select FITS image (*.fts, *.fits) as the file type.
4. Click Export to save your image in FTS format.

Conclusion

While there is no direct PDF to FTS converter, you can convert PDF content to FTS by extracting images and using astronomical imaging software. GIMP with the FITS plugin or SAOImage DS9 are excellent choices for this workflow.
