iOS Printing with image and text - iphone

Question

I am trying to print an image and some text above it. When I print the image it takes up the entire page I only want it in the center and about 320 x 480 pix. Someone told me I needed to use rects but I do not know how to do this. The code below is what I have so far, it just prints the image but it has no size constraints. Thank You.

[alert show];
[alert release];
return;
}

Answer 1

seems like you are only adding the picture to the printing item
print.printingItem = imageData;
have you tried creating the whole "picture" of what you want printed out (including the text and stuff) and sending that to the printer instead?

Answer 2

I use the following to insert a simple image into and text into PDF, might point you in the right direction
- (IBAction)generatePdfButtonPressed:(id)sender{
pageSize = CGSizeMake(612, 792);
NSUserDefaults *data = [NSUserDefaults standardUserDefaults];
NSString *projectTitle = [data stringForKey:#"pName1"];
NSString *fileName = [NSString stringWithFormat:#"%#.pdf", projectTitle];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *pdfFileName = [documentsDirectory stringByAppendingPathComponent:fileName];
[self generatePdfWithFilePath:pdfFileName];}
and then...
- (void) drawText{
CGContextRef currentContext = UIGraphicsGetCurrentContext();
CGContextSetRGBFillColor(currentContext, 0.0, 0.0, 0.0, 1.0);
NSString *textToDraw = #"Lorem ipsum ";
UIFont *font = [UIFont systemFontOfSize:14.0];
CGSize stringSize = [textToDraw sizeWithFont:font
constrainedToSize:CGSizeMake(pageSize.width - 2*kBorderInset-2*kMarginInset, pageSize.height - 2*kBorderInset - 2*kMarginInset)
lineBreakMode:UILineBreakModeWordWrap];
CGRect renderingRect = CGRectMake(kBorderInset + kMarginInset, kBorderInset + kMarginInset + 350.0, pageSize.width - 2*kBorderInset - 2*kMarginInset, stringSize.height);
[textToDraw drawInRect:renderingRect
withFont:font
lineBreakMode:UILineBreakModeWordWrap
alignment:UITextAlignmentLeft];
}
- (void) drawImage{
//paint chart
NSData* imageData = [[NSUserDefaults standardUserDefaults] objectForKey:#"chartImageP1"];
UIImage* chartImage = [UIImage imageWithData:imageData];
[chartImageBack drawInRect:CGRectMake( (pageSize.width - chartImageBack.size.width/2)/2, 70, chartImageBack.size.width/2, chartImageBack.size.height/2)];
[chartImage drawInRect:CGRectMake( (pageSize.width - chartImage.size.width/2)/2, 70, chartImage.size.width/2, chartImage.size.height/2)];}
- (void) generatePdfWithFilePath: (NSString *)thefilePath{
UIGraphicsBeginPDFContextToFile(thefilePath, CGRectZero, nil);
NSInteger currentPage = 0;
BOOL done = NO;
do
{
//Start a new page.
UIGraphicsBeginPDFPageWithInfo(CGRectMake(0, 0, pageSize.width, pageSize.height), nil);
//Draw some text for the page.
[self drawText];
//Draw an image
[self drawImage];
done = YES;
}
while (!done);
// Close the PDF context and write the contents out.
UIGraphicsEndPDFContext();}
