![]() So to answer your question, my guess as to why PDFDocument doesn't support HTTPS is because a synchronous initializer like this isn't the recommended way to load something over a network, and thus, putting a lot of work into designing it for that purpose was not a priority. Once the data's all downloaded, you can then use the resulting Data object to initialize a PDFDocument. By loading the PDF data asynchronously, you can provide progress information for your user, along with a way to cancel the operation, and if something goes wrong, like the network going down in the middle of the download, you can handle that error in a sensible way. ![]() The reason I suggest this is that loading data from the network can take time, especially with PDF files which can sometimes be quite large, and if you just try to load the file synchronously on the main thread, you'll block it and make your app appear as if it is locked up. What I'd actually recommend doing instead would be to use an asynchronous API like URLSession to load the PDF data from the server. In your case, you can work around the problem trivially by using Data's try init(contentsOf:), which does support HTTPS, and then initializing your PDFDocument from that, but this isn't actually the best way to go about it. However, when you look a little deeper, it's not as much of a problem as it appears at first glance. It's often a good assumption that if the documentation doesn't say otherwise, the API probably only accepts file: URLs. Some only take file URLs, some only take HTTP, some take HTTP, and HTTPS, and the documentation often doesn't say anything about which is going to be the case. Fixed bug with PDFKit.Watermark for High Sierra.Ĭreated 18th August 2014, last changed 28th November 2019įeedback: Report problem or ask question.At first glance, this appears to be kind of a common problem in the Cocoa frameworks many APIs take URLs, but in many cases, it's not clear what schemes they will accept.Fixed PDFKit.Watermark to work better with watermarks on several pages.MBS("PDFKit.Watermark" $pdf 0 Watermark PDF Page::WatermarkImage 0 0 0 0 0) Or use PDFKit.GetPDFDocument to get a PDF for storing in a container. Your changes are only done in memory, so please remember to write modified pdf back to disk, e.g. You can do similar with DynaPDF with insert image command ( DynaPDF.InsertImage) and alpha set ( DynaPDF.SetAlpha). You can watermark several pages by calling this function in a loop.ĭon't forget to use PDFKit.Release to later release memory. This modifies an in memory PDF Document which you can create by opening one using PDFKit.Open, PDFKit.OpenContainer, PDFKit.OpenPath or PDFKit.OpenURL.
