Hi,
I can't quite get my head around obj-c sometimes, so i was just
wondering if anyone could point me in the right direction.
I've got a fairly simple coredata app that I code and use to keep
track of some work stuff (I run my own business), and it automatically
generates composite images for me. At the moment it's set to re-size
the original images and fit them into a 3x4 grid, but if theres only a
few images it looks very odd, so I want to change it so if there are
less than 8 images it lays them out differently. In non code what I
want to do is:
for NSMakeRect(0,0,x,y)
origin to stay at 0,0
calculate scale factor (sf) by dividing 225(required height) by the
original height: sf = 225 / originalheight
x = requiredwidth / sf
y = originalheight
I can't work out how to get the original height and width of the
image, and I think i'm getting confused with number formats, I've got
the following at the moment but my width variable is coming out as
null?
NSArray* kitImages = [kit
valueForKeyPath:@"kitItems.kitItemProduct.productImage"];
int ki = [kitImages count];
NSLog(@"Number of images: %i",ki);
//calc image width
float width = 300 / ki;
NSLog(@"Width: %@",width);
I'd appreciate any help.
Many Thanks
Amy
