iTextSharp fields rename does not work with Merge

由 不羁岁月 提交于 2019-12-07 20:16:36
问题 This is a follow up to another question I had earlier, after the merge of PDF files with form fields worked successfully, if fields with same names do appear then they are not getting their distinct values from their original documents, it looks like a field with the same name propagate its values to the following fields which have the same name. This is the code to merge and rename in 2 separate functions: public byte[] MergeFiles(IList<DBForms> forms) { if (forms.Count < 1) return null;

Border around the page in PDF with MPDF

由 北慕城南 提交于 2019-12-07 14:44:07
问题 I have an html page that has borders around, but when I use the MPDF, he breaks a div and not puts border above or down of the broken div, does anyone know how to fix it, or let each page with border around? 回答1: Perhaps you could try a hack using watermarks: http://www.olivettorestaurante.com.br/mpdf/examples/example35_watermarks.php A full page square image used as watermark could work. I know, a bit triky, but sometimes MPDF turns weird when facing some problems... :/ A better answerd

R: monte carlo integration using Importance Sampling

由 徘徊边缘 提交于 2019-12-07 06:19:55
问题 I have an integral to evaluate "x^(-0.5)" ; x in [0.01,1] for which I am using Importance Sampling MC : The theory says that an approximate PDF has to be used to compute the expected value (which will almost surely converge to the mean - value of the integral) After plotting the given integral, and exponential PDF, based only on the plots, I chose the rexp and dexp to generate the PDF - and my code looks like this - #Without Importance Sampling set.seed(1909) X <- runif(1000,0.01,1) Y <- X^(
