php - Imagick PHP 中的奇怪行为

转载作者：可可西里更新时间：2023-10-31 23:18:29

所以我的应用程序中的 Imagick 有一个相当特殊的问题。该应用程序使用上层输入来创建他们选择颜色、品种等的“宠物”。生成宠物后，它的十六进制值将保存到数据库中，然后他们可以为该宠物装备元素。此功能的演示位于 here

我遇到的问题是，当用户为宠物装备元素或宠物从婴儿变大时，第二个脚本会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黑，如下所示:

如您所见，宠物在创建时比在更新时轻得多。我认为问题可能在于 COMPOSITE_MULTIPLY 和 COMPOSITE_OVERLAY 在创建时和在更新时表现不同，因为除了从数据库中拉取与拉取之外，脚本在步骤上没有变化来自用户输入(值存储正确)。

老实说，我不确定这是创建太亮还是更新太暗的问题。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，更新后的脚本生成的颜色似乎更接近您在第一个屏幕截图中看到的十六进制值，这让我觉得创建的颜色太浅了。

宠物创建脚本:

所有输入都被馈送到函数中(标记被压缩到一个数组中)。

这里是更新脚本，它接受一个宠物对象和一个可选的元素对象，它将找到所需的元素并将其添加到宠物中。这也将扩展到包括现有项目，如果这样的事情对这个问题很重要的话。
