saveToFile is not a function

Creator 2.x
#1

版本：1.7.0-beta2
平台：mac
let dirpath = jsb.fileUtils.getWritablePath() + 'ScreenShoot/'; if( !jsb.fileUtils.isDirectoryExist(dirpath)){ jsb.fileUtils.createDirectory(dirpath); } let name = 'ScreenShoot-' + (new Date()).valueOf() + '.png'; let filepath = dirpath + name; let size = cc.winSize; let rt = cc.RenderTexture.create(size.width, size.height); cc.director.getScene()._sgNode.addChild(rt); rt.setVisible(false); rt.begin(); cc.director.getScene()._sgNode.visit(); rt.end(); rt.saveToFile('ScreenShoot/' + name, cc.IMAGE_FORMAT_PNG, true, function() { cc.log('save succ'); rt.removeFromParent(); if (func) { func(filepath); } }); return filepath;
我使用上面这段代码在原生平台上截屏，但是会报错：

调试了一下发现貌似是在create的时候就报错了

手动顶一下@jare

使用1.7 beta3一样报错，使用1.6.2正式版是ok的。
是不是新版本不支持这个saveToFile这个方法了？

谢谢反馈，这个在1.6.2是手动绑定的函数，1.7中漏了此函数。稍后修复。

#6

cc.IMAGE_FORMAT_PNG是哪里定义的？我这里是undefined。查了一下1.6，也没有这个枚举定义。

#7

creator.d.ts里面

#8 
/** Image formats */
export enum ImageFormat {		
	JPG = 0,
	PNG = 0,
	TIFF = 0,
	WEBP = 0,
	PVR = 0,
	ETC = 0,
	S3TC = 0,
	ATITC = 0,
	TGA = 0,
	RAWDATA = 0,
	UNKNOWN = 0,
	getImageFormatByData = 0,	
}

那应该是cc.ImageFormat.PNG吧，你写的是cc.IMAGE_FORMAT_PNG.

你好，用saveToFile会让截屏的图片保存在手机上吗？
