Imagick PHP中的奇怪行为

分类：PHP作者：编程之家

所以我在我的应用程序中有一个与Imagick相当特殊的问题.该应用程序使用uper输入创建一个“宠物”,他们选择颜色,品种等.生成宠物后,它的十六进制值将保存到数据库中,然后他们可以在以后为该宠物装备物品.此功能的演示位于here

我遇到的问题是有一个第二个脚本,当用户装备物品或者宠物从婴儿到成人老化时,更新并重新保存宠物.当我运行这个脚本时,宠物突然看起来比创建时更暗,如下所示：

Horse at creation

enter image description here

正如您所看到的,宠物在创作时比在更新时轻得多.我认为问题可能在于COMPOSITE_MULTIPLY和COMPOSITE_OVERLAY在创建更新时的行为方式不同,因为除了从数据库拉出而不是从用户输入拉出(值正确存储)之外,脚本的步骤不同.

老实说,我不确定这是创作太轻或更新太暗的问题.重要的是它必须保持一致,人们不会希望他们创造的宠物的颜色随机改变！老实说,似乎更新的脚本产生的颜色更接近你在第一个截图中看到的十六进制值,这让我觉得创作太过轻微.
