使用 Fedora 和 Inkscape 制作一张简单的壁纸
================
![inkscape-wallpaper](https://cdn.fedoramagazine.org/wp-content/uploads/2016/10/inkscape-wallpaper-945x400.png)
在先前的两篇 Inkscape 的文章中,我们已经[介绍了 Inkscape 的基本使用、创建对象][18]以及[一些基本操作和如何修改颜色。][17]
在接下来的介绍中,我们会集合这些新的技巧,并且创建我们的第一个作品 —— 一张简单的壁纸。
### 更改文档大小
回顾先前的教程时,你可能会注意到主画板上的默认文档尺寸是一个黑色边框的矩形。Inkscape 中默认文档的大小是 A4 纸大小:

][16]
对于这张壁纸而言,我们会将尺寸改为**1024px x 768px**。要改变文档的尺寸,进入`File` > `Document Properties...`。在文档属性对话框中自定义文档大小区域中输入宽度为 `1024`,高度为 `768` ,单位是 `px`:

页面上文档的轮廓大概像这样:

][14]
### 绘画背景
接下来,我们会画一个和文档一样大的矩形。因此选择**矩形工具**来画一个矩形,并使用工具控制栏来调整矩形的大小。

][13]
接着在矩形中添加一个渐变填充。如果你需要复习添加渐变,请阅读先前添加色彩的[那篇文章][12]。

][11]
你的矩形也可以设置轮廓颜色。 使用填充和轮廓对话框将轮廓设置为 **none**。

][10]
### 绘制图样
接下来我们画一个三角形,使用 3 个顶点的星型/多边形工具。你可以按住 `CTRL` 键给三角形一个角度并使之对称。

][9]
选中三角形并按下 `CTRL+D` 来复制它(复制的图形会覆盖在原来图形的上面),**因此在复制后确保将它移动到别处。**

][8]
如图选中一个三角形,进入`Object` > `FLIP-HORIZONTAL`(水平翻转)。

为这三个三角形重新着色。让它看上去和背景和谐。

][5]
选中所有的三角形并复制,以填充你的样式:

### 导出背景
最后,我们需要将我们的文档导出为 PNG 文件。点击 `File` > `EXPORT PNG`,打开导出对话框,选择文件位置和名字,确保选中的是 `Drawing` 标签,并点击 `EXPORT`。
