電暈：圖像裁剪

Question

如何在corona sdk中裁剪從相機卷中選擇的圖像？

我試過掩蓋 following this tutorial 但這給了我彩色背景與我的裁剪圖像。我需要單獨裁剪圖像。

Answer 1

local localGroup = display.newGroup() 

local backGround = display.newImage(localGroup,"backGround.png") 
local imageForCrop = display.newImage(localGroup,"path.png") 

local mask = graphics.newMask("mask.png") 

localGroup:setMask(mask.png) 

--then Capture , or if you don't need to capture circle you can use easy the display.captureBounds(boundsData)
