pdf

问题 I'm trying to build a simple PDF document signing routine, using PHP, openssl, and the Zend framework (for pdf redering/handling). I've found this, but it simply won't work, Zend is not able to open any pdf's, not even Zend's own test pdf and Zend will not report why, only that it 'cannot'. I'm pretty sure I would be able to create the keys/certs effectively as that is well documented, but is there a solid approach to attaching the generated certificate to the PDF as the above Zend extension

问题 In an R markdown report rendered to both PDF and HTML, I would like to colorize text with different transparencies. For example, I would like to use the same orange with 3 different alpha values (0.3, 0.6, 1.0). Nicholas Hamilton provides a function to color text regardless of the output format (PDF/latex or HTML). An updated MWE of the fct. was provided by Mark Neal. To work with transparent colors, the colFmt() function needs to be adapted somehow as far as I see. What I tried gplots:

问题 Update 2: I have uploaded sample at https://1drv.ms/u/s!Al69FgQ8jwmZbgiBMXLLM4j5sbU?e=vyGF4m Can you please check. I am stuck at last step. However, please confirm if other appraoch is correct. Update 1: I have confirmed the flow. So I am clear on it. As part of that digital signing PDF document flow , We want to use third party to provide Signed Hash of PDF. Here are steps: There is 3rd party inhouse system which will generate PDF document from word. That PDF will be send to another service
