In this topic we will discuss how pixopedia uses mouse for various actions on image. Beside this topics, we will see how to set various cursor shapes for use with this program. Image panning and foreground and background color picking is discussed.

Mouse

Navigation
is actually straight forward mouse movement. You simply click on page tabs to control set of actions. To choose some action click on the button, to access global parameters or to apply input/output action or some global action click on button located on speed panel, etc..

Selecting Shape
Regarding on desired action (Draw, Rtch, Adjust, Warp....) by clicking the right mouse button while mouse cursor is in image manipulation area pop-up menu attached to given action is displayed. Some actions may not have any pop-up menu attached. If there is some menu displayed, it can be one of two types, described under shapes & brushes section.
Choose desired shape by navigating with mouse cursor and click left mouse button. Shape is selected. All further brush actions upon image are determined by shape selected.

Drawing Shape on the Mask (Image)
Mouse movements for drawing various shapes on the mask are divided in three categories: free hand drawing, geometric shapes drawing and text rendering.

1. In case of free hand drawing, no matter is it connected or disconnected, the principle is the same:
Press left mouse button, hold it down and move the mouse in desired direction.
To stop drawing, simply release the finger from the left mouse button.

2. In case of geometric shape drawing, after shape is selected, press the left mouse button, hold it down, and move the mouse to create desired shape. While moving an XOR-ed shape is temporary drawn onto image. To apply the desired shape, simply release the left mouse button. Selected action is performed through shape drawn.

3. In case of text rendering, click on the left mouse button, the pop-up panel will be displayed (as shown on the left). In the edit field, enter the desired text, by pressing Change font button standard font dialog form will be shown. You can change the size, style of text font. After those actions, press OK button if you want to proceed with text rendering, otherwise press Cancel button.
If OK button is clicked, XOR-ed text will be shown on image, without pressing any mouse button, move your text to desired position. To perform text rendering, press again left mouse button. Text antialiasing can be performed by super-sampling method, higher the amount, the better antialiasing is performed. Text rotation angle is specified by slider and its associated edit field and spinner buttons.

Control mouse movement
are set of movements for panning the picture inside the image manipulation area. Panning can performed with scroll bars if specified so or via CTRL mouse movement. To pan an image that is larger then IMA press CTRL button on your keyboard, and while holding it pressed, press the left mouse button and hold it down. Move the mouse to pan the picture. After desired panning, release the mouse button and CTRL button as well. To select foreground color do the same thing, but release the mouse button without any mouse movement (clicking). The foreground color will be selected. To select background color do the same thing as above, but with right mouse click.

Keyboard

Esc
key is used to stop execution of some time consuming action (autobrush, 3x3filters on large images,etc..). If you want to stop some action, press Esc key and hold it down, until action stops.
In the new program version Esc key will control thread cancelation, so you will not need to hold the key pressed.

Other Keys
will be added as a shorcut keyboard keys through new versions of program.
