I want to generate a pdf of UIScrollView whose content size is near about 320*2000. if i use current graphic image context to capture the scroll view layer, then it only captures the visible part of the scroll view not the whole layer of that scroll view.
i am using the below code.
Code:
-(void)CreatePdf:(id)sender
{
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *saveDirectory = [paths objectAtIndex:0];
NSString *saveFileName = @"myPDF.pdf";
[self writePDFAma];
CGRect arect=CGRectMake(0, 0, 768, 1024);
CreatePDFFileAma(arect, nil);
}
-(void) writePDFAma
{
UIImage *image;
NSData *data;
UIAlertView *successAlert;
UIAlertView *failureAlert;
//
NSArray *documentPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
// // This should be our documents directory
NSString *saveDiirectory = [documentPath objectAtIndex:0];
// // Our PDF is named 'Example.pdf'
NSString *saveFileName = @"FormImage2.JPG";
// // Create the full path using our saveDirectory and saveFileName
NSString *finalPath = [saveDiirectory stringByAppendingPathComponent:saveFileName];
//NSLog(@"%@",finalPath);
CGSize asize=CGSizeMake(_scrollview.frame.size.width, _scrollview.frame.size.height);
//NSLog(@"%d..%d",mainViewAma.frame.size.width, mainViewAma.frame.size.height);
UIGraphicsBeginImageContext(asize);
[[_scrollview layer] renderInContext:UIGraphicsGetCurrentContext()];
image = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
data = UIImageJPEGRepresentation(image, 1.0);
BOOL catch;
if(!catch){
if ([[NSFileManager defaultManager] createFileAtPath:finalPath contents:data attributes:nil])
{
successAlert = [[UIAlertView alloc] initWithTitle:@"Success" message:@"Doodle was successfully saved to the Photo Library." delegate:self cancelButtonTitle:@"Close" otherButtonTitles:nil];
//[successAlert show];
[successAlert release];
} else {
failureAlert = [[UIAlertView alloc] initWithTitle:@"Failure" message:@"Failed to save doodle to the Photo Library." delegate:self cancelButtonTitle:@"Close" otherButtonTitles:nil];
//[failureAlert show];
[failureAlert release];
}
}
}
void CreatePDFFileAma (CGRect pageRect, const char *filename)
{
// This code block sets up our PDF Context so that we can draw to it
//some code here
CGContextRef pdfContext;
CFURLRef url;
CFMutableDictionaryRef myDictionary = NULL;
NSArray *documentPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
// // This should be our documents directory
NSString *saveDirectory = [documentPath objectAtIndex:0];
// // Our PDF is named 'Example.pdf'
//NSString *saveFileName = @"PDFForm2.pdf";
// // Create the full path using our saveDirectory and saveFileName
NSString *finalPath = [saveDirectory stringByAppendingPathComponent:saveFileName];
NSURL * aurl=[[NSURL alloc]initFileURLWithPath:finalPath];
url=(CFURLRef)aurl;
// This dictionary contains extra options mostly for 'signing' the PDF
myDictionary = CFDictionaryCreateMutable(NULL, 0,
&kCFTypeDictionaryKeyCallBacks,
&kCFTypeDictionaryValueCallBacks);
CFDictionarySetValue(myDictionary, kCGPDFContextTitle, CFSTR("AMA FORM PDF"));
CFDictionarySetValue(myDictionary, kCGPDFContextCreator, CFSTR("My Name2"));
// Create our PDF Context with the CFURL, the CGRect we provide, and the above defined dictionary
pdfContext = CGPDFContextCreateWithURL (url, &pageRect, myDictionary);
// Cleanup our mess
CFRelease(myDictionary);
CFRelease(url);
// Starts our first page
CGContextBeginPage (pdfContext, &pageRect);
// Draws a black rectangle around the page inset by 50 on all sides
CGContextStrokeRect(pdfContext, CGRectMake(50, 50, 768, 1024));
// This code block will create an image that we then draw to the page
CGImageRef image;
CGDataProviderRef provider;
CFURLRef pictureURL;
documentPath = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
// // This should be our documents directory
saveDirectory = [documentPath objectAtIndex:0];
NSString *saveFileName2 = @"FormImage2.JPG";
// // Create the full path using our saveDirectory and saveFileName
NSString *finalPath2 = [saveDirectory stringByAppendingPathComponent:saveFileName2];
NSURL * aurl2=[[NSURL alloc]initFileURLWithPath:finalPath2];
pictureURL=(CFURLRef)aurl2;
provider = CGDataProviderCreateWithURL (pictureURL);
CFRelease (pictureURL);
image = CGImageCreateWithJPEGDataProvider(provider, NULL, TRUE, kCGRenderingIntentDefault); //DataProvider (, NULL, true, kCGRenderingIntentDefault);
CGDataProviderRelease (provider);
CGContextDrawImage (pdfContext, CGRectMake(0, 0,768, 1024),image);
CGImageRelease (image);
CGContextEndPage (pdfContext);
// We are done with our context now, so we release it
CGContextRelease (pdfContext);
}

i would realy appreciate if anyone can show the track or provide me some refrence code or links to solve my problem
You are capturing the visible content only because your scroll view is sized match the visible content only, which it should be. You need to resize your scrollview to match the content you need to capture before you start the drawing code using something like this:
Code:
self.scrollView.frame = CGRectMake(0, 0, "your content width here", "your content height here");
After you are done drawing make sure to resize your scroll view to back, in this case to the container view:
Code:
self.scrollView.frame = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height);
t worked on my iPad app. I hope it works for you.
Hi Currently am having images and textview inside a scrollview i just need to convert all these things/contexts into pdf context could any one help by steering me in the right direction???thanks in advance.
