WriteRainbow is an easy-use Application. There are two main windows: the start window and the drawing window.
When you start WriteRainbow, you enter into the Start window.
You will see three thumbnails in the center. They represent the last 3 files you opened before. (The first time you start WriteRainbow, those three will be blank.) You can click on it to open it.
There are 4 buttons:
After you click the "New File" icon, or click one of the thumbnail, or browsed and selected a local file, the Drawing window will be shown.
This one shows an empty document with the background image only. Now you draw directly on it. It is just as simple as that.
To activate the menu, click and hold on any point of the screen.
If you click the Settings button on the menu bar, you will see the following setting page.
Now we get to the advanced features here. You see three sections in the Settings page. On top you also see two buttons. The cancel button cancels whatever you selected here and go back to the Drawing page. The OK button accepts the change and go back to the Drawing page.
The first section on top is the section for setting the drawing line. By default you are drawing "RainbowB", which stands for Rainbow color with black outline. The other choices are:
Zoom in and then edit, and you will get a much better visual effect. Open a document, and activate the menu bar. Please know that the document will be zoomed in around the point you click, so click on the place you want to write.
If you select RainbowB or Rainbow, you can adjust how fast the color changes, using the "Rainbow length" slider. Slide it to the left if you want the color to change quickly; to the right if you want the color to change gradually.
Then the color wheel for picking color if you select Normal, WhiteOutline, or BlackOutline. For these three choices, you can further adjust the brightness and the transparency of the color. The effect will be previewed in the Preview section.
For any of the 5 choices above, you can also adjust the line width.
For convenience, the last 5 colors you picked are shown in the Color selection history section. You can pick one by clicking it.
Besides drawing on the page, you can also stamp icons on it. You pick an icon from the icon sections by clicking it. You can also specify how big the stamp you want it to be. The default is shown here as 48x48.
You can pick a background image for your document here by clicking at one of the built-in one. Or you can click the "Browse" button and select an image from the local storage as the background.
When you first start WriteRainbow, you will see the following image:
Use your finger or a stylus to draw directly on the document and you will see something like this

Click the thumbnail above to re-open the last document. Click and hold any point to activate the menu item.
Click the Email button, and you will see
