Question & Answer :
Location has been galore Questions late astir drafting PDF’s.

Sure, you tin render PDF’s precise easy with a UIWebView however this cant springiness the show and performance that you would anticipate from a bully PDF spectator.

You tin gully a PDF leaf to a CALayer oregon to a UIImage. Pome equal person example codification to entertainment however gully a ample PDF successful a Zoomable UIScrollview

However the aforesaid points support cropping ahead.

UIImage Methodology:

1. PDF’s successful a UIImage don’t optically standard arsenic fine arsenic a Bed attack.
2. The CPU and representation deed connected producing the UIImages from a PDFcontext limits/prevents utilizing it to make a existent-clip render of fresh zoom-ranges.

CATiledLayer Methodology:

3. Theres a important Overhead (clip) drafting a afloat PDF leaf to a CALayer: idiosyncratic tiles tin beryllium seen rendering (equal with a tileSize tweak)
4. CALayers cant beryllium ready up of clip (rendered disconnected-surface).

Mostly PDF viewers are beautiful dense connected representation excessively. Equal display the representation utilization of pome’s zoomable PDF illustration.

Successful my actual task, I’m processing a PDF spectator and americium rendering a UIImage of a leaf successful a abstracted thread (points present excessively!) and presenting it piece the standard is x1. CATiledLayer rendering kicks successful erstwhile the standard is >1. iBooks takes a akin treble return attack arsenic if you scroll the pages you tin seat a less res interpretation of the leaf for conscionable little than a 2nd earlier a crisp interpretation seems.

Im rendering 2 pages all broadside of the leaf successful direction truthful that the PDF representation is fit to disguise the bed earlier it begins drafting.Pages are destroyed once more once they are +2 pages distant from the centered leaf.

Does anybody person immoderate insights, nary substance however tiny oregon apparent to better the show/ representation dealing with of Drafting PDF’s? oregon immoderate another points mentioned present?

EDIT: Any Ideas (Recognition- Luke Mcneice,VdesmedT,Matt Gallagher,Johann):

• Prevention immoderate media to disk once you tin.
• Usage bigger tileSizes if rendering connected TiledLayers
• init often utilized arrays with placeholder objects, alternitively different plan attack is this 1
• Line that photographs volition render sooner than a CGPDFPageRef
• Usage NSOperations oregon GCD & Blocks to fix pages up of clip.
• call CGContextSetInterpolationQuality(ctx, kCGInterpolationHigh); CGContextSetRenderingIntent(ctx, kCGRenderingIntentDefault); earlier CGContextDrawPDFPage to trim representation utilization piece drafting
• init’ing your NSOperations with a docRef is a atrocious thought (representation), wrapper the docRef into a singleton.
• Cancel unnecessary NSOperations Once you tin, particularly if they volition beryllium utilizing representation, beware of leaving contexts unfastened although!
• Recycle leaf objects and destruct unused views
• Adjacent immoderate unfastened Contexts arsenic shortly arsenic you don’t demand them
• connected receiving representation warnings merchandise and reload the DocRef and immoderate leaf Caches

Another PDF Options:

• Getting Hyperlinks wrong a PDF (and present and present)

  • Knowing the PDF Rect for nexus positioning
  • Changing PDF annot datestrings
  • Getting the mark of the nexus (Getting the leaf figure from the /Dest array)

• Getting a array of contents

• Papers rubric and Key phrases

• Getting Natural Matter (and present and Present and present (positioning targeted))

• Looking(and present) (doesn’t activity with each PDFs (any conscionable entertainment bizarre characters, I conjecture it’s an encoding content however I’m not certain) -Recognition BrainFeeder)

• CALayer and Disconnected-Surface Rendering - render the adjacent leaf for accelerated/creaseless show

Documentation

• Quartz PDFObjects (Utilized for meta data, annotations, thumbs)
• Abobe PDF Spec

Illustration initiatives

• Pome/ ZoomingPDF - zooming, UIScrollView, CATiledLayer
• vfr/ scholar - zooming, paging, UIScrollView, CATiledView
• forehead/ leaves - paging with good transitions
• / skim - every thing it appears (PDF scholar/application for OSX)

I person physique specified benignant of exertion utilizing approximatively the aforesaid attack but :

• I cache the generated representation connected the disk and ever make 2 to 3 photographs successful beforehand successful a abstracted thread.
• I don’t overlay with a UIImage however alternatively gully the representation successful the bed once zooming is 1. These tiles volition beryllium launched mechanically once representation warnings are issued.

Each time the person commencement zooming, I get the CGPDFPage and render it utilizing the due CTM. The codification successful - (void)drawLayer: (CALayer*)bed inContext: (CGContextRef) discourse is similar :

CGAffineTransform currentCTM = CGContextGetCTM(discourse); if (currentCTM.a == 1.zero && baseImage) { //Cipher perfect standard CGFloat scaleForWidth = baseImage.dimension.width/same.bounds.dimension.width; CGFloat scaleForHeight = baseImage.dimension.tallness/same.bounds.measurement.tallness; CGFloat imageScaleFactor = MAX(scaleForWidth, scaleForHeight); CGSize imageSize = CGSizeMake(baseImage.measurement.width/imageScaleFactor, baseImage.dimension.tallness/imageScaleFactor); CGRect imageRect = CGRectMake((same.bounds.dimension.width-imageSize.width)/2, (same.bounds.measurement.tallness-imageSize.tallness)/2, imageSize.width, imageSize.tallness); CGContextDrawImage(discourse, imageRect, [baseImage CGImage]); } other { @synchronized(content) { CGPDFPageRef pdfPage = CGPDFDocumentGetPage(content.pdfDoc, pageIndex+1); pdfToPageTransform = CGPDFPageGetDrawingTransform(pdfPage, kCGPDFMediaBox, bed.bounds, zero, actual); CGContextConcatCTM(discourse, pdfToPageTransform); CGContextDrawPDFPage(discourse, pdfPage); } } 

content is the entity containg the CGPDFDocumentRef. I synchronize the portion wherever I entree the pdfDoc place due to the fact that I merchandise it and recreate it once receiving memoryWarnings. It appears that the CGPDFDocumentRef entity bash any inner caching that I did not discovery however to acquire free of.
