Matrix Orbital GLK12232-25-FGW - Manual (Page 33)

Parameters Parameter Length Description
X 1 Left bounds.
Y 1 Top bounds.
W 1 Width
H 1 Height
D 1 Data
Description Drawing a bitmap to the GLK12232-25, without first uploading the
image to the memory can be a very useful feature for drawing images
that are not used very often. In order to accomplish this, you must
supply the display module with the X,Y coordinates, representing the
top left corner of where you would like to draw the bitmap on the
screen, as well as the width and the height of the bitmap. After you have
supplied this data you may then upload the bitmap data to the
GLK12232-25. The bitmap data is encoded into bytes horizontally and
is transfered the same as if you were uploading a file, see Section 12 on
page 42 for more information about transferring data to the display
module.
NOTE Drawing a bitmap directly to the display is supported by flow control.
This command is not available in I2C mode.

8 Bar Graphs and Drawing
8.1 Introduction
Supplementary to the ability of the GLK12232-25 to display bitmaps and fonts, the GLK12232-25 also
allows for a robust 2D drawing environment. With the ability to draw by pixel, line or rectangle, as well as
the ability to continue a line to form a polygon, we are certain that you will spend less time, developing and
creating better looking projects. With the addition of custom bar and strip graphs, you are sure to find the
right tools to make any graphical layout a success.
