General

1. Drawing

You can draw by pressing 1 finger on the screen and move it. It's equivalent to pressing the mouse left button down on your computer and moving the mouse.

2. Scrolling view

You can slide the view by pressing and moving at least 2 fingers on the screen.

3. Zooming and de-zooming

You can zoom or de-zoom the view by pinching 2 fingers on the screen. Alternatively you can pinch and move your fingers to zoom and scroll the view at the same time.
Note that zooming in the view does allow you to see more accurately but is not more precise in term of mouse inputs sent to the computer (an iPad doesn't catch more touch events with a view at 200% than at 100%). For more accuracy you should use the zoom tool inside your CG software on your computer.

4. Tools panel

Since version 3.0 there's now a tools panel on the left (for iPad only. For iPhone it's another view available by pressing the top right button). The first button's purpose is to configure the settings of iGraphTablet (see section Settings below). The two following buttons are to show/hide the ruler and the t-square. Then you got the mouse button selection and the undo/redo shortcuts. The refresh shortcuts totally refresh the picture on your iOS device (in case you got some artefacts on it). Finally, the "shortcuts" section provides an access to your custom shortcuts and a button to manage them (see section Shortcuts below).

5. Ruler and T-Square

The Ruler button display the ruler. With it, you can trace lines on your drawing as if you were on a real paper sheet. Move and rotate the ruler to the desired position, then press your finger inside the zone delimited by the dotted lines and move your finger for a perfect line ! The T-Square does the same but allows you to trace two perpendiculars.

5. Displays

The Displays button at the bottom right allows you to choose the screen or the region of screen to display. The last element of the list, "manage regions...", is a button allowing you to create your own regions (see just below).

6. Regions

You can create regions representing a portion of the screen. Only this portion of the screen will be sent by iGraphTablet Server. You will then be able to interact only with the important part of the screen and will benefit from a faster frame rate, the picture sent being smaller.

 

Connection

1. Connection test

In version 3, like before, you can connect by detecting automatically your computer with Bonjour's help, or connecting manually by entering the IP address of your computer where iGraphTablet Server is running. But now you'll see a "Test" button: you'll be able to test the connection before you try to connect. If your computer isn't reachable, iGraphTablet will tell it to you. If it's reachable but iGraphTablet Server doesn't respond, it will tell you too. It has never been easier to troubleshoot the connection problems !

2. Multiple connections

iGraphTablet Server allows you to connect simultaneously multiple iOS devices. A good example is to use an iPhone or an iPad Mini for viewing a region corresponding to the tools panel of your application, while your iPad will be used to work on the region corresponding of the picture itself. The maximum number of iOS devices connected simultaneously depends only on your CPU, your iOS devices models and your network bandwidth capacity.

 

Settings

1. Trace helper

There's now a trace helper showing you exactly where the mouse inputs will be. It's really useful when the lag between your inputs and the returned picture is too important. In the settings you can choose the trace helper color (or disable it entirely) and its width in pixels. Remember that it has nothing to do with the size or the color of your brush in your computer's CG software !

2. Image size

You can choose the scale of the picture sent by iGraphTablet Server: full size, half size or fourth size. Smaller size is faster but a lot less pretty, of course !

3. Image quality

You can choose the encoding quality of the picture sent by iGraphTablet Server: high, medium or low. Lower quality is faster but a lot less pretty, of course !

5. back to left after right click

Ok, this one isn't so easy to explain. With iGraphTablet you can choose to interact with the left or right mouse button. But most of the time, the right mouse button's only purpose is to show a popup menu. And in order to click on the menu, you need to use the mouse left button. This settings does exactly that: when activated, if you tap a first time on the screen it does a right click, and then when you tap a second time it reverts back to left mouse click. Disable this setting by example if your CG Software draws in one color when you move the mouse by pressing the left button and in another color when you move the mouse by pressing the right button.

 

Shortcuts

1. Shortcuts properties

In the tools panel, when you tap on the "Edit shortcuts..." bottom button, you'll be able to manage your shortcuts. Select one in the left list and then customise it by changing the name, the key stroked, the modifiers (hold alt, cmd/windows, ctrl or shift simultaneously) and the predefined picture template. Note that the shortcuts created by default works only on Photoshop: for the CG software you use you may have to modify them. Note too that you shouldn't forget to choose a key to press, otherwise the "empty" warning will be displayed and nothing will be sent to the computer when you'll use the shortcut.

2. Add a shortcut

Simply tap on the "+" button on the bottom left of the screen.

3. Move a shortcut in the list

Tap on the "Edit" button on the bottom right of the screen: you will toggle the edit mode in the list. You'll then be able to move a shortcut to the top or bottom by pressing the icon on the right of the shortcut and moving it. When finished, press the "Done" button on the bottom right corner to exit the edit mode of the list.

4. Remove a shortcut

Tap on the "Edit" button on the bottom right of the screen: you will toggle the edit mode in the list. By taping on the left symbol of a shortcut you'll be able to delete it. When finished, press the "Done" button on the bottom right corner to exit the edit mode of the list.
