UIScrollView *innerScrollView; UIScrollView *outerScrollView; } ``` PTPDFViewCtrl is a utility class that can be used for interactive rendering of PDF documents. On iOS, PTPDFViewCtrl derives from UIView. PTPDFViewCtrl defines several coordinate spaces and it is important to understand their differences: * Page Space refers to the space in which a PDF page is defined. It is determined by a page itself and the origin is at the lower-left corner of the page. Note that Page Space is independent of how a page is viewed in PDFView and each page has its own Page space. * Canvas Space refers to the tightest axis-aligned bounding box of all the pages given the current page presentation mode in PDFView. For example, if the page presentation mode is e\_single\_continuous, all the pages are arranged vertically with one page in each row, and therefore the Canvas Space is a rectangle with possibly large height value. For this reason, Canvas Space is also, like Page Space, independent of the zoom factor. Also note that since PDFView adds gaps between adjacent pages, the Canvas Space is larger than the space occupied by all the pages. The origin of the Canvas Space is located at the upper-left corner. * Screen Space (or Client Space) is the space occupied by PDFView and its origin is at the upper-left corner. Note that the virtual size of this space can extend beyond the visible region. * Scrollable Space is the virtual space within which PDFView can scroll. It is determined by the Canvas Space and the current zoom factor. Roughly speaking, the dimensions of the Scrollable Space is the dimensions of the Canvas Space timed by the zoom. Therefore, a large zoom factor will result in a larger Scrollable region given the same Canvas region. For this reason, Scrollable Space might also be referred to as Zoomed Canvas Space. Note that since PDFView adds gaps between pages in Canvas Space and these gaps are not scaled when rendered, the scrollable range is not exactly what the zoom factor times the Canvas range. For functions such as `-SetHScrollPos:`, `-SetVScrollPos:`, `-GetCanvasHeight`, and `-GetCanvasWidth`, it is the Scrollable Space that is involved. * `ContainerView` * Deprecated * The view that displays the PDF, that is the content view of a UIScrollView.

Note Progressive rendering is useful when a PDF page contain lots of elements (e.g. many vector paths, text, or many little images). When progressive rendering is enabled PDFNet will use painter algorithm to draw the page. This way user may be able to see partially rendered page. If a page contains only a single large image, there would be no visible benefit from progressive rendering. **Declaration** Objective-C ```highlight - (void)SetProgressiveRendering:(BOOL)progressive withInitialDelay:(int)delayMilliseconds withInterval:(int)intervalMilliseconds; ``` Swift ```highlight func setProgressiveRendering(_ progressive: Bool, withInitialDelay delayMilliseconds: Int32, withInterval intervalMilliseconds: Int32) ``` **Parameters** | `progressive` | if true the view will be rendered progressively | | ---------------------- | -------------------------------------------------------- | | `delayMilliseconds` | delay before the progressive rendering timer is started. | | `intervalMilliseconds` | delay between refreshes.

Currently, this would make lines with sub-pixel width to be one-pixel wide. This option is turned on by default. | * `-SetImageSmoothing:` Enable or disable image smoothing. The rasterizer allows a trade-off between rendering quality and rendering speed. This function can be used to indicate the preference between rendering speed and quality. Note The image smoothing option has effect only if the source image has higher resolution that the output resolution of the image on the rasterized page. PDFNet automatically controls at what resolution/zoom factor, ‘image smoothing’ needs to take effect. Image smoothing is enabled by default. **Declaration** Objective-C ```highlight - (void)SetImageSmoothing:(_Bool)enabled; ``` Swift ```highlight func setImageSmoothing(_ enabled: Bool) ``` **Parameters** | `enabled` | True to enable image smoothing, false otherwise. | | --------- | ------------------------------------------------ | * `-SetGamma:` Sets the gamma factor used for anti-aliased rendering.

By default overprint is only enabled for PDF/X files. **Declaration** Objective-C ```highlight - (void)SetOverprint:(PTOverprintPreviewMode)op; ``` Swift ```highlight func setOverprint(_ op: PTOverprintPreviewMode) ``` **Parameters** | `op` | `e_ptop_on`: always enabled; `e_ptop_off`: always disabled; `e_ptop_pdfx_on`: enabled for PDF/X files only. | | ---- | ----------------------------------------------------------------------------------------------------------- | * `-SetOCGContext:` Sets the Optional Content Group (OCG) context that should be used when viewing the document. This function can be used to change the current OCG context. Optional content (such as PDF layers) will be selectively rendered based on the states of optional content groups in the given context. Note Unlike `-[PTPDFDraw SetOCGContext:]` this method copies the given context. As a result, in order to modify the state of OCG groups in the current context use `-GetOCGContext` to obtain the currently selected content and then modify states. **Declaration** Objective-C ```highlight - (void)SetOCGContext:(nonnull PTContext *)ctx; ``` Swift ```highlight func setOCGContext(_ ctx: PTContext) ``` **Parameters** | `ctx` | Optional Content Group (OCG) context, or `nil` if the rasterizer should render all content on the page. | | ----- | ------------------------------------------------------------------------------------------------------- | * `-GetOCGContext` Get the Optional Content Group (OCG) context associated with this PTPDFViewCtrl.

If there is an OCG context associated with the view, optional content (such as PDF layers) will be selectively rendered based on the states of optional content groups in the given context. * `-UpdateOCGContext` Prompts the PDFViewCtrl to update its list of optional content groups. Call this method if you modify the PDFDoc in a way that adds or removes a layer. For example, after using Stamper to create a stamp. **Declaration** Objective-C ```highlight - (void)UpdateOCGContext; ``` Swift ```highlight func updateOCGContext() ``` * `-HideAnnotation:` Disable rendering of a particular annotation. This does not change the annotation itself, just how it is displayed in this viewer instance. **Declaration** Objective-C ```highlight - (void)HideAnnotation:(nonnull PTAnnot *)annot; ``` Swift ```highlight func hideAnnotation(_ annot: PTAnnot) ``` **Parameters** | `annot` | The annotation object to cease drawing for. | | ------- | ------------------------------------------- | * `-ShowAnnotation:` Enable rendering of a particular annotation.

GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://apryse.gitbook.io/api-markdown-test/api-docs/ios/classes/ptpdfviewctrl.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
