There is not a tool that I know of do do this. But there is a button in the Xcode Organizer, under Screenshots, labeled “Save as Launch Image”. If you set up your code to dynamically generate the image you want, you can run your app on various devices and grab images of it running, and then use those images as your launch images. You may have to modify them a little bit, but it’s certainly easier than creating each one from scratch.
Launch image manager for iOS

Table 5-4 (about half way down) this Apple doc page suggests sizes for the launch images for iOS:
Device Portrait Landscape
iPhone and iPod touch 320 x 480 pixels Not supported
640 x 960 pixels (@2x)
iPhone 5 640 x 1136 pixels (@2x) Not supported
iPad 768 x 1024 pixels 1024 x 768 pixels
1536 x 2048 pixels (@2x) 2048 x 1536 pixels (@2x)
My app has a photo background at launch so at present I have to use GIMP to crop/resize the photo for each of these, which is fiddly.
Is there a tool to do this automatically ?
One other complication is that there are a couple of logos in the image too, ideally they will be in separate layers, so they can stay legible and tidily laid out for each size/orientation.
