ps画九宫格辅助线肿么吧拉倒空白处

1、首先要了解下微信九宫格的尺寸，一般是1800x1800的像素，照片太大了发朋友圈会显示不完全，我们先在ps里建一个1800x1800的画布，点击“文件--新建”
/iknow-pic.cdn.bcebos.com/d058ccbf6c81800a6d589477be3533fa828b470d"target="_blank"title="点击查看大图"class="ikqb_img_alink">/iknow-pic.cdn.bcebos.com/d058ccbf6c81800a6d589477be3533fa828b470d?x-bce-process=image%2Fresize%2Cm_lfit%2Cw_600%2Ch_800%2Climit_1%2Fquality%2Cq_85%2Fformat%2Cf_auto"esrc="https://iknow-pic.cdn.bcebos.com/d058ccbf6c81800a6d589477be3533fa828b470d"/>
2、宽度和高度改为1800x1800

3、将照片拖进ps画布里

4、ctrl+t调整图片和画布一样大小，调整好了点击上方对号
