Bitmap2LCD is a tool for programming small Graphic LCDs in embedded systems.
From Version V2.8b, you can split the “File Explorer” and the “Graphics Preview & Editors” (red arrow) into two separate Windows (See button pointed by blue arrows)
The “Graphics Preview and Editors” Window can then be resized.
Use the same buttons to reunite the windows.

1 . Click Select Contiguous Pixels Button (red arrow)
2 . Click inside the area of pixels (a group of pixels separated from the others, an island (blue arrow)
–> The seleted group of pixels becomes red
3. Click the Selection Area button (green arrow)
4. Move the mouse cursor inside the selected area (blue arrow) and drag the area to the destination (orange arrow below)
5. Click Paste button
6. To “delete” the moved area, press the escape key ( to clear the addition of pixels to the last selection) and press the delete key (in this case the background color should be white )

1. Pick Source Color with color picker A inside the work canvas
2. Pick Target Color with Color picker B inside the work Canvas
3. Replace every color A pixel with color B in the Work Canvas (green arrow)

Data of one display line of pixels (direction can be either in colums or in rows) can be separate in a sub array (green arrow)
Example of this kind of data output (Checkbox enabled must be set )
[[ — Array prefix example
[data for line 1]
[data for line 2]
[data for line n]
]] — Array suffix example

Outdated information :
Since v2.6B, there’s a new toolbar at the top of the graphic (blue arrow)
When importing a graphic file, you can choose to resize the graphic size in the graphic preview (yellow arrow) or turn the graphic or reload the original graphic.
If the graphic is much larger in size than the work canvas, you will see a “blue frame” in the preview, frame which shows the size of the Work Canvas. You can move this area to the graphic detail you wish to import. In this case, the later message box resize to fit should be answered with NO.
When you want to resize the graphic, click on the selection button (yellow button) and then define the size on the image with mouse. The preview will be resized.
When ready import the graphic (red arrow) to the floating selection layer above the work canvas. When ready paste the floating selection layer.

OBSOLETE Article : For older versions
All the configuration settings of the Bitmap2LCD tool have been reorganized and grouped in one single window :
The main settings, the output file header syntax settings, the pixel to data array orientation setting , the optional postprocessing and a new user friendly pixel to data array organisation display.
Let’s see how to configure the GLCD data output settings :
The generated data array file can be configured to meet the syntax requests of your compiler or assembler. There are many possible settings, to make it possible to match the tool with most of the compilers of the market.
At first, you define the table data settings
As next, you define the header syntax ( output file header tab)
>> To edit file header blue arrow )
As next, you define the way the data arrays are arranged to correctly fit in the DDRAM of your LCD controller. ( Data orientation ) These settings must be compatible with the LCD display functions in the GLCD Library you use in your project.
More about File Header syntax ( output file header tab )
The script components [&***] can be included only once and will be replaced by the data or value when the data array is generated. Not needed script components can be erased.
[&NAME]
The [$NAME] and the image size and position are optional and can be placed optionally anywhere in the header.
[&SIZE]
Same for Size of Data
[&TRUEORG]
This is the script component if present in the file, to indicate that you want to have the XPOS and YPOS origins of a reduced dynamic table of constants ( a part of the display you want to change ) given from the X0,Y0 corner you selected in the table translation manager window.
[&XPOS]
[&YPOS]
[&WIDTH]
[&HEIGHT]
The corner position on the Work Canvas and the size of the converted graphic area can be exported into the file.
There are additional script components for font generation and data compression.

Output of the GLCD data array in a binary file
The converter data output feeds a built in hexadecimal editor and is saved to disk in a binary file (*.hex)
Output of the GLCD data array in a INTEL Hex format
Details about Intel Hex Data Output
Output of the GLCD data array in a text file for the compiler or assembler, format 8, 16 or 32 bit data
The converter data output feeds a built in text editor and can saved to disk in a text file
( *.c , *.h , *.asm , “.lib etc..)
Next to the data file, a rich text file (*.rtf) which contains all GLCD conversion parameters is written to disk, in the user defined “Documents folder”.

Since V2.3 and upwards, Bitmap2LCD supports the 4,16 and 32 level grayscale controllers. ( Newly implemented are the 4 and 32 gray levels capability )
Color images and pictures can be imported and converted to 4, 16 and 32 gray levels into the work canvas. The software tool then generates the pixel data array in the selected arrangment, 2, 4 or 5 bits per pixel.
Here’s a list of grayscale LCD controllers, featuring 4, 16 and 32 gray levels.
