iphone平铺图像 [英] iphone tiling an image

问题描述

我有一个1280 x 1664的图像，我想使用Apple给我们的ScrollViewSuite示例，但我需要将此图像剪切到多个缩放级别。

<那么，是否有人知道如何在多个缩放级别平铺图像。必须有一种简单的方法将图像耕种到256x256而不用手工通过photoshop切割？

解决方案

很棒的查找。我根据您的发现进行了一些研究，并设法将row和col添加到输出文件名中。我还将图像调整为我希望图像的百分比。所以我现在可以从1张大图片中完成所有操作。

 转换bigimage.png -resize 25％-crop 256x256 -set filename ：tile％[fx：page.x / 256 + 1] _％[fx：page.y / 256 + 1]+ repage + adjointile_25 _％[filename：tile] .png
  

非常感谢帮助我，它为我节省了很多时间。希望我帮你了？

I have an image which is 1280 x 1664 and I want to use the ScrollViewSuite example that Apple gives us but I need to cut this image up to multiple zoom levels.

So, does anybody know how I can tile an image at multiple zoom levels. There must be an easy way to tilling an image to 256x256 without cutting it by hand via photoshop?

解决方案

great find. I did a bit of researching from what you found and I've managed to add the row and col to the output filename. I've also resized the image to what percentage I want the image to be. So I can now do it all from 1 large image.

convert bigimage.png -resize 25% -crop 256x256 -set filename:tile "%[fx:page.x/256+1]_%[fx:page.y/256+1]" +repage +adjoin "tile_25_%[filename:tile].png"

Thanks a lot for helping me out, its saved me a lot of time. Hopefully I've helped you out?
