[BUG 256.34] Calculate Text Rect gives crazy values on iOS (fine on PC)

[AyreGuitar]

Not sure if this is a new thing with one of the Betas as I haven't used the Calculate Text Rect object before.

Basically works as it should on PC, but just gives values in the millions on iOS (and they can keep changing even when the text it is calculating doesn't, perhaps they're pointing to random memory somehow?)
I've included a simple example file for others to try requires the Calculate Text Rect object.

Maybe it's just my system: using XCode 4.3.3 on OSX Lion and iPod touch 4G iOS 5.1.1

I'd love to get a fix for this soon, as I can't see any other way to calculate size of text.
Thanks!

Thanks, will look into it

Anders - Thanks!

After a bit of digging it looks like there have been some changes to CServices.m in one of the more recent betas/releases, in particular the drawText routine and I don't think the calcRect has been taken into account (since 3rd party extension).

I've found that this couple of changes to calcRect help get the correct height, but not width:

-(void)CalcRect
{
	// CRect rc;
	CRect rc=CRectNil(); //This gives slightly better values, not huge (but still wrong)
    rc.right=maxWidth; //This gives correct height but width is always maxWidth

Hopefully it will save you a bit of time

Anders - Just wondering if there's any update on this (I haven't seen a fix mentioned in any of the Betas)?

[AyreGuitar]

Anders - Anything? I'd fix this myself if I could figure out how!

Ah, sorry I must have missed your reply here.

This bug is fixed and will be in the next patch.

You can replace the method "CalcRect" in the CRunCalcRect extension with this code snippet:

-(void)CalcRect
{
	//Font
	CFontInfo* fontInfo = [[CFontInfo alloc] init];
	fontInfo->lfFaceName = [[NSString alloc] initWithString:fontName];
	fontInfo->lfHeight = fontHeight;
	fontInfo->lfItalic = (unsigned char)(fontItalic ? 1 : 0);
	fontInfo->lfUnderline = (unsigned char) (fontUnderline ? 1 : 0);
	CFont* font=[CFont createFromFontInfo:fontInfo];

	//Size
	CGSize size = [text sizeWithFont:[font createFont] constrainedToSize:CGSizeMake(maxWidth, 100000) lineBreakMode:0];
	calcWidth = (int)size.width;
	calcHeight = (int)size.height;

	[fontInfo release];
	[font release];
}
