Map windows can contain the following objects:
If the Map is bigger than the window itself, scroll bars will appear. The map can be scrolled using these bars. It can also be scrolled by using the scroll wheel on your mouse (if it has one). Vertical scrolling is done by the scroll wheel on your mouse and horizontal scrolling is done by pressing and holding the CTRL key while using the scroll wheel on your mouse.
Here is a list of common toolbar buttons. The available buttons will change depending on the type of maps.
|Zooms in or out||To zoom in, left click on the map. To zoom out, right click on the map.|
|Region of Interest (ROI)||Selects a Region of Interest(ROI). Just click and drag to select the ROI. A red rectangle will appear (known bug). The ROI is used in only two operations: Crop and Histogram. All other operations are always done on the whole map even if an ROI is defined. To remove the ROI, simply click at one point and do not drag.|
|Cropping||Crops the map to the desired dimension. If no ROI is selected, a dialog will appear asking to enter the coordinate of the crop window.|
|Paint||Inverts the pixel at the clicked location and all the pixels of the same state that touches it. Great way to remove objects in BinMap.|
|Erase||Erases a selected region. To erase, simply click and drag over the region to erase. Every pixel in the selection will be set to 0.|
|Line||Draws a line of color 0. The thickness of the line can be selected by right clicking on the button. When you select a new size, the button will become unpressed even if it was pressed before.|
Typical information showed:
- Coordinates of the mouse cursor on the map: These are map’s coordinates, not display coordinates. So it takes into account the scaling factor. The origin (0; 0) is at the top left corner of the map.
- Scale factor of the display: When the scaling factor changes, the map stays the same in memory. Only its display changes.
- Color index of the pixel under the cursor or its value
