``nxlines`` NX Line Drawing
|
|||
|
|
===========================
|
|||
|
|
|
|||
|
|
A very simple graphics example that just exercised the NX line drawing logic.
|
|||
|
|
|
|||
|
|
The following configuration options can be selected:
|
|||
|
|
|
|||
|
|
- ``CONFIG_EXAMPLES_NXLINES_VPLANE`` – The plane to select from the frame- buffer
|
|||
|
|
driver for use in the test. Default: ``0``.
|
|||
|
|
- ``CONFIG_EXAMPLES_NXLINES_DEVNO`` – The LCD device to select from the LCD driver
|
|||
|
|
for use in the test: Default: ``0``.
|
|||
|
|
- ``CONFIG_EXAMPLES_NXLINES_BGCOLOR`` – The color of the background. Default
|
|||
|
|
depends on ``CONFIG_EXAMPLES_NXLINES_BPP``.
|
|||
|
|
- ``CONFIG_EXAMPLES_NXLINES_LINEWIDTH`` – Selects the width of the lines in pixels
|
|||
|
|
(default: ``16``).
|
|||
|
|
- ``CONFIG_EXAMPLES_NXLINES_LINECOLOR`` – The color of the central lines drawn in
|
|||
|
|
the background window. Default depends on ``CONFIG_EXAMPLES_NXLINES_BPP`` (there
|
|||
|
|
really is no meaningful default).
|
|||
|
|
- ``CONFIG_EXAMPLES_NXLINES_BORDERWIDTH`` – The width of the circular border drawn
|
|||
|
|
in the background window. (default: ``16``).
|
|||
|
|
- ``CONFIG_EXAMPLES_NXLINES_BORDERCOLOR`` – The color of the circular border drawn
|
|||
|
|
in the background window. Default depends on ``CONFIG_EXAMPLES_NXLINES_BPP``
|
|||
|
|
(there really is no meaningful default).
|
|||
|
|
- ``CONFIG_EXAMPLES_NXLINES_CIRCLECOLOR`` – The color of the circular region
|
|||
|
|
filled in the background window. Default depends on
|
|||
|
|
``CONFIG_EXAMPLES_NXLINES_BPP`` (there really is no meaningful default).
|
|||
|
|
- ``CONFIG_EXAMPLES_NXLINES_BORDERCOLOR`` – The color of the lines drawn in the
|
|||
|
|
background window. Default depends on ``CONFIG_EXAMPLES_NXLINES_BPP`` (there
|
|||
|
|
really is no meaningful default).
|
|||
|
|
- ``CONFIG_EXAMPLES_NXLINES_BPP`` – Pixels per pixel to use. Valid options include
|
|||
|
|
``2``, ``4``, ``8``, ``16``, ``24``, and ``32``. Default is ``16``.
|
|||
|
|
- ``CONFIG_NSH_BUILTIN_APPS`` – Build the NX lines examples as an NSH built-in
|
|||
|
|
function.
