HE: Bitmap Grid

Use the Bitmap Grid widget to display a grid-based drawing area on the HMI, controlled by PLC data.

Each cell in the grid represents a single unit that can be painted with a color based on a buffer value. By writing values into the buffer and triggering a redraw, the PLC can draw, update, or clear graphical content on the HMI in a deterministic and repeatable manner.

This widget is available only on iMX6 platforms

Bitmap Grid Attributes
Tag: Buffer	Select or create a buffer tag for the color data of the grid. Each byte in the buffer corresponds to one cell in the grid. The required buffer size is Rows × Columns, with a maximum of 9600 bytes. Each byte value maps to a color defined in the Bitmap Values configuration.
Tag: Redraw	Link a bit tag. When the value changes from 0 to 1, the bitmap grid redraws itself based on the current buffer contents.
Tag: Clear Bitmap	Link a bit tag to trigger clearing the bitmap grid. When this bit is set to 1, all grid cells are cleared. The bit is automatically reset to 0 after the clear operation.
Lock Element	Check to prevent any adjustments or changes to the element's configuration.
Grid Properties
Rows	Define the number of rows in the bitmap grid. Range: 0 - 200 Note: The total number of cells (Rows × Columns) must not exceed 9600
Columns	Define the number of columns in the bitmap grid. Range: 0 - 200 Note: The total number of cells (Rows × Columns) must not exceed 9600
Paint Direction	Determines how buffer values are mapped to grid cells. Horizontal - Values are painted row by row, from left to right Vertical - Values are painted column by column, from top to bottom
Grid Lines Color	Click the drop-down arrow to select the color of the grid lines.
Grid Lines Thickness	Define the thickness of the grid lines. Range: 0.0 - 5.0
Bitmap Values	Bitmap Values enable defining which numeric values correspond to which colors. To configure the Values: Select Bitmap Values > Collection in the Properties Window. In Bitmap Values Configuration, click Add Bitmap Value. Add the Values and select its corresponding Color. Note that Values may be non-consecutive.
