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. Thus I think the rendering speed in Acrobat can be worse in lower spec models.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.

I have a late-2017 MacBook Pro with i7 CPU and 16G ram, plus Radeon Pro 560 graphics card. But when I opened the file in Preview, I got angry.Īcrobat reader is always not so responsive compared to other apps. At that time I was expecting the effect of my second example. Then I thought, although it is a bit blurry in Preview, it should be at least readable. The reason I brought this after using Acrobat for so long is that the rendering speed of this book in Acrobat is really slow, and I got an inconsistent response for moving next and previous pages with either my mouse or keyboard. I am a researcher, thus reading PDF files from different sources is my daily job. I have several of this kind of files to search and read regularly. I've tested this page in both Acrobat reader and Preview, the result is the same as I've shown in my post. It is a scanned book page, from a 700 page scanned book. Toggle the Use LCD font smoothing setting in System Preferences -> General panel - and gauge any improvement.Ĭheck this link for an example file for the first example. You should consider open-type, sans-serif fonts for detail content such as chemical and mathematical formulas, and I don't mean Arial either. The Affinity (Designer, Photo, Publisher) applications are an example of a private PDF library that generates PDF v1.7 content. Some third-party applications bring along their own PDF library based on newer PDF specifications, and a custom print panel that accesses that private PDF library.

If you are exporting content to PDF on the Mac from the standard print panel, this is as good as it is going to get. Preview and Skim are both based on the Apple's PDFKit framework which in turn, is based on PDF v1.3 - an ancient specification. If you want the best PDF handling and imaging, then use Adobe Acrobat Reader, as only Adobe can remain current with the latest PDF specifications. Thank you all for reading, if you suffer the same, please leave a note!Īs this is a user-to-user support community, none of us have any better insight than you as to what Apple does or does not test, or the physical peripherals involved in that testing. Why it comes so difficult with PDF? Does Apple not do test for older screens anymore? But I think the text in Safari is crisp enough and I like the rendering style of that.

I know Apple doesn't want to render PDF like windows do, with sub-pixel. But since PDFKit is widely used across the system, especially in Safari, it is legit to request the files to be at least sharp enough to read. I am not dreaming about apple PDFKit to render PDF like an expert. Also, I don't see any complaints mentioning the even worse situation on a low res display. I've noticed that there are some complaints about such problems before, but the discussions are all closed by now, and the problem is still there. Imagery PDF in Preview: (the CaCl2 part is an annotation made in Preview) Check the pics below that I cropped from 1680 x 1050 LCD screen. If you want to open a PDF with any app using PDFKit provided by the system, especially when you connected to an old monitor, it is non-readable blurry. I am now using High Sierra 10.13.6 (17G65)
