我们可以使用iText库将多页PDF转换为多页TIFF吗？
You may convert PDF to images using one of the following tools:
Ghostscript (cross platform, see this answer) Image Magick (cross platform and based on Ghostscript , with command line convert -density 300 image.pdf image.tif ) xPDFRasterizer (cross platform, commercial, from authors of xPDF) ByteScout PDF Renderer SDK (Windows only, commercial - Disclosure: I am related to ByteScout) Also, you should consider the following important things when converting PDF to TIFF images:
PDF rendering is the heavy task that requires lot of memory especially if you are rendering high quality images as output (300 DPI or higher) Generating TIFF files is also quite a heavy task so you may consider converting each page from PDF file into a separate file and then merge all pages into final TIFF file. You may want to preserve original PDF files in addition to generated TIFF images: PDF is the actual replacement for TIFF format and is better because PDF is searchable, may contain both image representation and the original text on top, provides much lesser file size and by using embedded fonts provides scalable high quality text printing.
