pdf-generation

I'm writing a CAD application that outputs PDF files using the Cairo graphics library. A lot of the unit testing does not require actually generating the PDF files, such as computing the expected bounding boxes of the objects. However, I want to make sure that the generated PDF files "look" correct after I change the code. Is there an automated way to do this? How can I automate as much as possible? Do I need to visually inspect each generated PDF? How can I solve this problem without pulling my hair out? You could capture the PDF as a bitmap (or at least a losslessly-compressed) image, and

I am using the DOMPDF library to create an invoice in PDF. This document can be in French, Russian or English, but I am having trouble printing Russian characters. First, I tried to use UTF-8 encoding and placed the meta tag in the head of the HTML page to be converted: <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> But that didn't work. Then I inserted this meta tag inside the BODY tag, and it helped solve the problem with French characters. But Russian characters still don't work. I have also tried to convert Russian characters into HTML entities, but that too does not

We're using Fast Reports to create reports but we're not very happy with the quality of the PDFs it creates. I know we can plug in other PDF components instead of the one that comes with FastReports so my question is What good PDF components are there out there (Free or Commercial) for Delphi? Ideally it should not require any dlls. Edit: I bought Gnostice in the end as it had the FastReports integration, source available and a fairly good reputation. I did however find an issue (after I had bought it) with exporting multipage reports from FastReports to PDF where the component leaks memory

I want to loop over a plot and put the result of the plot in a PDF . The following code is used to do this: What this does is loop 3 times and plot 3 different plots from the iris dataset. Then it should save it to the C:/ drive. The PDF files are created, but are corrupted. for(i in 1:3){ pdf(paste("c:/", i, ".pdf", sep="")) plot(cbind(iris[1], iris[i])) dev.off() } To drawn lattice plots on the device, one needs to print the object produced by a call to one of the lattice graphics functions. Normally, in interactive use, R auto prints objects if not assigned. In loops however, auto printing
