photos

问题 For a special project, I need to find an API/DLL/Library to help me create a big image using parts of this image. For example, if someone take 4 pictures representing the 360 degrees around him, he will be able to create one big image (panorama) by stitching the 4 images together using special algorithm that recognize some patterns. I know how to do this in Photoshop and I know there are a lot of programs that to this on the internet. But I want one that will be controlled by programming.

问题 Does apple allows me to change the wallpaper of the iphone from my application? 回答1: The public iOS 4.0 API so far does not allow changing any of the iPhone wallpapers programmatically. Undocumented APIs are not supported by Apple, so no, I don't think they would allow it. However, technically it should be possible to do so. 回答2: Nope, no public APIs for it even with the latest SDK. You need to ask the user to save your image as a wallpaper manually. 来源： https://stackoverflow.com/questions

问题 When I use ALAssetsLibrary to get local photos it works fine. But after I delete some photos with the 'Photos' application my app crashes. Crash info is: "Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[NSOrderedSet enumerateObjectsAtIndexes:options:usingBlock:]: index 14 beyond bounds [0 .. 9]'".'14' It looks like the number of local photos still remains the same as befoore. And even after I quit my app and restart it again, it still crashes. Local photo access

问题 I am very new to AppleScript but have worked extensively (for years) with other scripting languages, so not entirely new to the game. I have just sadly said goodbye to Aperture and imported my nearly 100K digital images into Photos (so I'm also brand new to Photos). I would like to make a sane structure for finding images, i.e. Folders named for Year (e.g. 2004) contain Folders named for Month (e.g. 05) contain Albums named for each day for which there are images (e.g. 2004-05-03) (yes this

问题 I want to provide my users a photo picker which displays all their images similarly to the Photos app. Currently I can use two frameworks, the old Assets Library and the new Photos Library frameworks. Is there any recommendation how should I choose between these two? The documentation states: In iOS 8.0 and later, use the Photos framework instead of the Assets Library framework. The Photos framework provides more features and better performance for working with a user’s photo library. But as

问题 I am new to Java but not new to graphics I'm trying to expand my understanding with a project in which I'm displaying many photos of items using JLabels and Icons to display them, The items pictures are garnished from various locations on the net and so many sources. I've converted these into PNG files as they have transparent backgrounds to them. Thing is I wasted a whole weekend recently checking and re-checking some code because one item just would not display, following the logic to its
