### 5.4. ブラシの手早い作成

There are two methods to create a new brush:

1. First, the quick temporary method. You have an image area from which you want to make a brush, to be used with a tool like pencil, airbrush, etc. Select it with the rectangular (or elliptical) select tool, then Copy this selection. Immediately you can see this copy in the first position of the Brush Dialog, and its name is 「Clipboard」. It is immediately usable.

   This brush is temporary: it disappears when you close GIMP. You can make it permanent by clicking on the Duplicate this brush at the bottom of the brush panel.

2. ふたつめの方法は最初のよりも手が込んでいます。

   Select File → New… from the main menu.

   Set Width and Height for example to 30 pixels.

   In the Advanced Options, set for example the Color space to Grayscale and set Fill with to White.

   この新しい画像を拡大ズーム表示して、 「鉛筆で描画」ツールを使って黒で何か絵を描きます。

   Select File → Export As… from the main menu.

   Export the image with a `.gbr` extension in the `brushes` directory located inside your personal GIMP configuration folder.

   In the Brush Dialog, click on the button Refresh brushes .

   Your brush appears among the other brushes. You can use it immediately, without restarting GIMP.
