路径查找器 pathfinder 感觉翻译成路径建立器更好些,或者直接翻译成计算器。类似计算交集、并集的东西。

网上的教程提到了这个功能,但没讲清楚。因为本身也不常用,所以可能他们自己也搞不太清楚。找到了参考手册的解释,手册里说得算是很明白了。

Summary of Pathfinder effects

Add Traces the outline of all objects as if they were a single, merged object. The resulting shape takes on the paint attributes of the top object.

Intersect Traces the outline of the region overlapped by all the objects.
Exclude Traces all nonoverlapping areas of the objects, and makes overlapping areas transparent. Where an even number of objects overlap, the overlap becomes transparent. Where an odd number of objects overlap, the overlap becomes filled.

Subtract Subtracts the frontmost objects from the backmost object. You can use this command to delete areas of an illustration by adjusting the stacking order.

Minus Back Subtracts the objects in back from the frontmost object. You can use this command to delete areas of an illustration by adjusting the stacking order.

Divide Separates a piece of artwork into its component filled faces (a face is an area undivided by a line segment).
Note: When you use the Divide button in the Pathfinder panel, you can use the Direct Selection or Group Selection tool to manipulate the resulting faces independently of each other. You can also choose to delete or preserve unfilled objects when applying the Divide command.

Trim Removes the part of a filled object that is hidden. It removes any strokes and does not merge objects of the same color.
Merge Removes the part of a filled object that is hidden. It removes any strokes and merges any adjoining or overlapping objects filled with the same color.

Crop Divides artwork into its component filled faces, and then deletes all the parts of the artwork that fall outside the boundary of the topmost object. It also removes any strokes.

Outline Divides an object into its component line segments, or edges. This command is useful for preparing artwork that needs a trap for overprinting objects. (See Create a trap.)
Note: When you use the Outline button in the Pathfinder panel, you can use the Direct Selection or Group Selection tool to manipulate each edge independently. You can also choose to delete or preserve unfilled objects when applying the Outline command.

Hard Mix Combines colors by choosing the highest value of each of the color components. For example, if Color 1 is 20% cyan, 66% magenta, 40% yellow, and 0% black; and Color 2 is 40% cyan, 20% magenta, 30% yellow, and 10% black, the resulting hard color is 40% cyan, 66% magenta, 40% yellow, and 10% black.

Soft Mix Makes the underlying colors visible through the overlapping artwork, and then divides the image into its component faces. You specify the percentage of visibility you want in the overlapping colors.

Trap Compensates for potential gaps between colors in artwork by creating a small area of overlap (called a trap) between two adjoining colors.

About clipping masks

A clipping mask is an object whose shape masks other artwork so that only areas that lie within the shape are visible—in effect, clipping the artwork to the shape of the mask. The clipping mask and the objects that are masked are called a clipping set. You can make a clipping set from a selection of two or more objects or from all objects in a group or layer.

Object-level clipping sets are combined as a group in the Layers panel. If you create layer-level clipping sets, the object on top of the layer clips all of the objects below it. All operations that you perform on an object-level clipping set, such as transformations and alignment, are based on the clipping mask’s boundary, not the unmasked boundary. Once you have created an object-level clipping mask, you can only select the clipped content by using the Layers panel, the Direct Selection tool, or by isolating the clipping set.

Before masking (left) compared to after masking (right)

The following guidelines apply to creating clipping masks:

  • The objects that you mask are moved into the clipping mask’s group in the Layers panel if they don’t already reside there.
  • Only vector objects can be clipping masks; however, any artwork can be masked.
  • If you use a layer or group to create a clipping mask, the first object in the layer or group masks everything that is a subset of the layer or group.
  • Regardless of its previous attributes, a clipping mask changes to an object with no fill or stroke.

Tip: To create a semitransparent mask, use the Transparency panel to create an opacity mask.

作为个人非专业开发者,做了一些企业的网站了,大部分都是有了网站质量太差需要换的。
分享一下自己遇到的一些困难和经验:

什么都不懂,也不愿意了解的客户

如果客户什么都不懂,解释之后他们也依然没有兴趣搞明白,就不要接这种单子。
他们通常连打字,传图片,调整比例都弄不好,甚至录了视频教他们都没有用。这
些客户比较适合去找价格很高的一条龙服务的公司来做。我们自己做会面临很大的
沟通麻烦。而且自己的精力有限,这些地方就没办法做。

比如我曾经遇到一个客户,改旧版网站,完全重新做了,布局完全不一样,居然说
和以前的网站一样的版式。实在让人费解。另外比如分不清“网页直接下载下来”直接
替换和只是“界面上模仿”之间区别的客户。

还有最为重要的,如果这个客户说的话你听不懂,不管多少钱都不要再做,因为后期
沟通会更困难,你尽量控制项目质量,但结果就是白费时间,吃力不讨好。

信用较差的客户

信用差的单子千万不要接。一旦接了会非常麻烦。当然,如果碰到了,只能想开一点,
就当自己练习技术了。

长期不回复的客户

比如答复了客户的问题之后长期没有回复,你也无法进行下一步。隔了很长时间又来询问
进展。遇到这种,业务也很难进行下去。

要求支付定金

最开始我觉得朋友介绍也就不需要付定金了,但是会有这种情况,开发部分的工作做完了,
但是需要客户完善的内容,会因为客户比较忙而中断,甚至中断几个月之久。所以需要支付
定金,不然长时间拿不到报酬,定金至少算作一些报酬。

如果拿不到钱

拿不到钱也要看淡一些,人品各种各样,这种情况通过支付定金能避免就避免,如果碰到
狭隘一点,或者前期就沟通非常困难的,这种后续基本就很难有结果。

心态要好,态度要好

不论遇到什么样的客户,不要影响自己的心情和学习。自己尽力去解释清楚,开放的心态
去沟通。至于结果是什么样的,也不是自己能确定的。因为存在技术壁垒,沟通困难应该
是比较普遍的现象。

总结

这一段时间生意的经历,总结下来就是,可以终止这个给人做企业站点的生意了。
原因就是,需求很多要求太高,个人能力无法满足需求。遇到沟通困难的基本上就在不停地浪费时
间。大批的豆腐渣工程修得很累,客户也全然不知,所谓吃力不讨好,技术上也很难
有收获,所以不再做了。

复合路径有时候没办法镂空,非常奇怪。一度以为是不是软件出问题了。

结果是填充颜色规则的问题,有时候会有这种情况,具体可能和新建图形的操作有关。

解决方法:

调出属性窗口,点击下拉三角显示所有,
有两个填充规则,“非零环绕填充”“按奇偶填充”,切换一下。
这是两种用来判断闭合的空间是否填色的方法。
有时候结果会不一样。
具体解释可以搜索网页上的解释,也可以用adobe Ai的官方文档。

证件照ps更改底色.png

建立一个需要的底色的图层放到最下面

选择-颜色范围,选中图片现在的背景色

然后反选,建立蒙版。选区变成蒙版里的白色(透过),非选区就是黑色(不透)。

图片中的背景色就被遮住,显示的是最下面图层的底色了。

用不透明的白色画笔涂抹掉蒙版一些灰色(半透)的部分。
