[TOC] ## 概况 ### 背景 前几天,再次看到一些CI的Badge的时候,就想着要做一个自己的Badge: ![](https://box.kancloud.cn/2016-05-18_573c1da92264e.png) Badge 接着,我就找了个图形工具简单地先设计了下面的一个Badge: ![](https://box.kancloud.cn/2016-05-18_573c1da9380a8.png) Demo 生成的格式是SVG,接着我就打开SVG看看里面发现了什么。 ~~~ <?xml version="1.0" encoding="UTF-8" standalone="no"?> <svg width="1006px" height="150px" viewBox="0 0 1006 150" version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink"> <!-- Generator: Sketch 3.7 (28169) - http://www.bohemiancoding.com/sketch --> <title>phodal</title> <desc>Created with Sketch.</desc> <defs></defs> <g id="Page-1" stroke="none" stroke-width="1" fill="none" fill-rule="evenodd"> <rect id="Rectangle-1" fill="#5E6772" style="mix-blend-mode: hue;" x="0" y="0" width="640" height="150"></rect> <rect id="Rectangle-1" fill="#2196F3" style="mix-blend-mode: hue;" x="640" y="0" width="366" height="150"></rect> <text id="PHODAL" font-family="Helvetica" font-size="120" font-weight="normal" fill="#FFFFFF"> <tspan x="83" y="119">PHODAL</tspan> </text> <text id="idea" font-family="Helvetica" font-size="120" font-weight="normal" fill="#FFFFFF"> <tspan x="704" y="122">idea</tspan> </text> </g> </svg> ~~~ 看了看代码很简单,我就想这可以用代码生成——我就可以生成出不同的样子了。 ### ShowCase ![](https://box.kancloud.cn/2016-05-18_573c1da94eb6a.jpg) Finally 代码: GitHub: [https://github.com/phodal/brand](https://github.com/phodal/brand) ### SVG与SVGWrite SVG就是一个XML > 可缩放矢量图形(Scalable Vector Graphics,SVG) ,是一种用来描述二维矢量图形的XML 标记语言。 要对这个XML进行修改也是一件很容易的事。只是,先找了PIL发现不支持,就找到了一个名为SVGWrite的工具。 > A Python library to create SVG drawings. ## 步骤 ### Step 1: 基本图形 示例代码如下: ~~~ import svgwrite dwg = svgwrite.Drawing('test.svg', profile='tiny') dwg.add(dwg.line((0, 0), (10, 0), stroke=svgwrite.rgb(10, 10, 16, '%'))) dwg.add(dwg.text('Test', insert=(0, 0.2))) dwg.save() ~~~ 然后我就照猫画虎地写了一个: ~~~ import svgwrite dwg = svgwrite.Drawing('idea.svg', profile='full', size=(u'1006', u'150')) shapes = dwg.add(dwg.g(id='shapes', fill='none')) shapes.add(dwg.rect((0, 0), (640, 150), fill='#5E6772')) shapes.add(dwg.rect((640, 0), (366, 150), fill='#2196F3')) shapes.add(dwg.text('PHODAL', insert=(83, 119), fill='#FFFFFF',font_size=120, font_family='Helvetica')) shapes.add(dwg.text('idea', insert=(704, 122), fill='#FFFFFF', font_size=120, font_family='Helvetica')) dwg.save() ~~~ 发现和上面的样式几乎是一样的,就顺手做了剩下的几个。然后想了想,我这样做都一样,一点都不好看。 ### Step 2: 高级Badge 第一眼看到 ![](https://box.kancloud.cn/2016-05-18_573c1da96fd0a.jpg) Idea Prototype 我就想着要不和这个一样好了,不就是画几条线的事么。 ~~~ def draw_for_bg_plus(): for x in range(y_text_split + rect_length, width, rect_length): shapes.add(dwg.line((x, 0), (x, height), stroke='#EEEEEE', stroke_opacity=0.3)) for y in range(rect_length, height, rect_length): shapes.add(dwg.line((y_text_split, y), (width, y), stroke='#EEEEEE', stroke_opacity=0.3)) for x in range(y_text_split + max_rect_length, width, max_rect_length): for y in range(0, height, max_rect_length): shapes.add(dwg.line((x, y - 4), (x, y + 4), stroke='#EEEEEE', stroke_width='2', stroke_opacity=0.4)) for y in range(0, height, max_rect_length): for x in range(y_text_split + max_rect_length, width, max_rect_length): shapes.add(dwg.line((x - 4, y), (x + 4, y), stroke='#EEEEEE', stroke_width='2', stroke_opacity=0.4)) draw_for_bg_plus() ~~~ 就有了下面的图,于是我又按照这种感觉来了好几下 ![](https://box.kancloud.cn/2016-05-18_573c1da94eb6a.jpg) Finally
