.redbits R/O Property

Function:

A 16-bit value packing two 8-bit parameters: number of "red" bits per pixel (high byte) and the position of the least significant red bit within the color word (low byte).

Type:

Word

Value Range:

Value depends on the currently selected controller/panel

Details

The value of this property depends on the currently selected controller/panel. Selection is made through the Customize Project dialog, accessible through the Project Settings dialog. This property is only relevant for color panels (lcd.paneltype = 1 — PL_LCD_PANELTYPE_COLOR).

By taking the value of the high byte you can determine the number of the steps in which the brightness of the red "channel" can be adjusted. For example, if the high byte is equal to 5, then there are 32 levels for red.

This property also tells you the bit position and length of the red field in values used by lcd.forecolor, lcd.backcolor, and lcd.setpixel. If, for example, lcd.redbits = &h0500, lcd.bluebits = &h0605, and lcd.greenbits = &h050B, then you can reconstruct the composition of the red, green, and blue bits in a word: bit 15 -> gggggbbbbbbrrrrr <- bit 0. In this example, the red field is the first field and occupies 5 bits (4-0).
