Rotate NSImage in an NSImageView

As soon as I implemented this I realised how much of a pain it would be to copy out the arrow images, rotate them in an external program, then copy them back in. So I put some buttons next to the arrow image wells that allow the user to rotate the arrows within Slider itself.

Tile an NSImage Within an NSBezierPath

Another snippet I had to write during the great Slider rebuild.

I needed to be able to take an NSImage supplied by the user and tile it within an NSBezierPath defined by more user-set values.

The below example uses a rounded rectangle.

NSBitmapImageRep *theImage = [[NSBitmapImageRep alloc] initWithBitmapDataPlanes:NULL pixelsWide:imageSize.width pixelsHigh:imageSize.height
 bitsPerSample:8 samplesPerPixel:4 hasAlpha:YES isPlanar:NO
 colorSpaceName:NSDeviceRGBColorSpace bytesPerRow:0 bitsPerPixel:0];
 
[NSGraphicsContext saveGraphicsState];
[NSGraphicsContext setCurrentContext:[NSGraphicsContext graphicsContextWithBitmapImageRep:theImage]];
 
//bgImage can be any NSImage
NSColor *c = [NSColor colorWithPatternImage:bgImage];
[c set];
[path appendBezierPathWithRoundedRect:NSMakeRect(0, 0, imageSize.width, imageSize.height) xRadius:10.0 yRadius:10.0];
[path fill];
 
[NSGraphicsContext restoreGraphicsState];

Fancy Footer Update

I’ve updated the Fancy Footer snippet, now Trackbacks/Pingbacks will be able to find your posts – the previous version’s implementation was … lacking.

JS-Kit Comments + Greybox on Any Page

I realised that I didn’t want comments to be visible on the page in case one set of photos became wildly popular (yeah, right); which would result in a page of comments with a few photos, instead of a page of photos with maybe one or two comments. For some reason, Greybox popped into my head, and wouldn’t leave. A few hours later, this happened: Hangzhou Day 1.

Archive Annihilator Improved Again

The solution for the “sidebar explosion” effect that the Archive Annihilator caused occurred to me earlier today. The fix was pretty simple, the fact that I didn’t think of it right away is a little embarrassing.
