Wondering how your ebook will look on the new iPad with the high-resolution display? Let me break it down for you.
Firstly, your antiquated ebook made two months ago can be reformatted specifically for the iPad3. The images can be made larger to suit the higher-res display which has more pixels than HD TV. On older iPads this higher-res art will be scaled down to look fine. Unfortunately, the reverse is not true. Like baby chicks, images do not scale up gracefully. Your images that looked great on the iPad2 will look slightly jagged and pixellated on the new retina display of the iPad3. If your images were not optimized, they may already be big enough (but probably not).
Not bigger in your hand but bigger pain for developers.
Text is usually rendered on the fly by the device so it will be fine. The exception to this is text that has been rasterized. You’ll have to treat rasterized text just like images and double the size of the art for the new iPad.
Formatting rules are the same. Elements on your pages will not shift around unless your ebook is formatted with absolute pixel values. Dragonpencil always uses percentages and we recommend you do the same. For example you could shift an image away from the right edge with image:left-padding100px but, like $20 of gas, those pixels now get you only half as far they did before. The better way to do it would be image:left-padding20%. The exact syntax will vary depending on how you implement your formatting.
Expect new ebooks to have larger file sizes unless they have no images. This means longer download times. We are designing all new ebooks to this new higher-res standard. Dragonpencil is also the leading children’s book app company and our apps will also now be scaled up. While apps are always over 20MB, picture books have not been. But now file sizes will quadruple. This means that they won’t be downloadable via 3G/4G which limits downloads to 20MB. Not a huge deal but might push some publishers to apps vs. ebooks which is already the trend in picture books. Once a kid gets a reaction from touching an image in a book app, there’s no going back.
Your existing ebook can be reformatted if it looks clunky on the new iPad. New ebooks will have larger images and file sizes and work retroactively on the older iPads. And the iPad4 will make everything obsolete, especially this blog post.
