The Work Canvas

It’s the GRAPHIC EDITOR, the paintbox , You can draw pixels and shapes, import graphics into it. It has a user defined “color depth” which is the same as the target GLCD of the project.

Load a graphic

LOADING A GRAPHIC USING A STANDARD WINDOWS DIALOG OR LOADING IT FIRST INTO PREVIEW ? 

  • You can either use the Load Graphic Dialog ( red frame )

bitmap2lcd-load-graphic

Fig 5 )

OR

  • open / switch to the FILE EXPLORER
  • In the list of files, click to select your particular graphic file you want to load (fig6 blue arrow) , it appears in the GRAPHICS PREVIEW window at the right side.
  • Resize or turn/tilt the preview image using the buttons located at the top of the GRAPHIC PREVIEW.
  • Double click in the graphics viewer (yellow arrow) or the click the import button located at the top or bottom of the preview (fig6. Green arrow)

fig 6). File explorer view

If the graphic is larger than the WORK CANVAS a message box will ask you if you want resize the image to fit the canvas or not.

The Floating Selection Layer

MOVING THE GRAPHIC IMPORTED INSIDE THE FLOATING SELECTION LAYER ? 

The graphic will be imported in the FLOATING SELECTION LAYER not directly into the WORK CANVAS (fig7. imagine your own graphic inside the canvas)

The red frame (fig7. red arrow) around the canvas means that you will have to PASTE paste the graphic into the canvas after MOVING it, convert it. When outline frame is red, it means that a “floating ” SELECTION LAYER above the canvas is displayed…

The imported graphic can be moved around above the Work canvas : Move/drag the red frame to the desired canvas location with the left mouse button pressed. (fig7. blue arrows)

Then PASTE paste the FLOATING SELECTION LAYER (fig7. green arrow) The red frame in the frame and around the work canvas disappears. (There are also other ways to Paste, in menus, using the return key etc..)

Converting a bitmap to Monochrome

THRESHOLD LEVEL OR DITHERING ?

If you’re loading a COLOR graphic file to convert to black and white for MONOCHROME GLCDs you have the choice of applying a Black and White THRESHOLD level (red arrow), or applying a DITHERING (green arrow) with monochrome color reduction.

Dithering Parameters are located in the main menu of this Window

When the conversion to Black and white is finished, PASTE the floating SELECTION LAYER (Blue Arrow) to the WORK CANVAS

Projects, Artworks and Filenames

A PROJECT is a set of configuration settings ( There are many possible settings ! )

If you work on different GLCD projects, you can save the “current” settings inside a Project name. It’s the easiest and fastest way to switch from one to another.

A so called “Artwork” is a set of files related to the graphic source filename : In the below example a graphic saved for example as NewBitmap.BMP , will be converted to an output file called NewBitmap.h , and the associated touch panel file will then be named NewBitmap.TSC (Red Arrow)  

When you save your Artwork with”Define Artwork Name”  in the GLCD Graphic Tab (Red Frames), as a bitmap,  you will change the basic filenames

Color picker

Bitmap2LCD has built in functions which are very similar to the popular MS Paint program

You can select the foreground (PEN COLOR) and background colors (BRUSH COLOR) for painting and WRITING text by clicking in the color boxes of the menu window.

You can copy foreground color to background colors or swap them when clicking in the small boxes around the colors boxes.

Drawing tools

Buttons are located At the top of the Work Canvas

Write a text

Button is located at the top of the Work Canvas (blue arrow)

bitmap2lcd-write-text

There are 2 different ways to write text inside the work canvas :

  • The Text Field Editor
  • The single Line Text editor

Bitmap2LCD : The Configuration Settings Window

Bitmap2LCD is a tool for programming small Graphic LCDs in embedded systems.

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.

 

Bitmap2LCD Configuration Settings

 

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

  • Data Width format. ( 8,16 or 32 bits data)
  • Binary, Hex or decimal format.
  • Syntax of Data Byte/Word (make it compatible with your favorite compiler, assembler)
  • Type of file (extension)

 

 

bitmap2lcd output settings

 

As next, you define the header syntax ( output file header tab)

>>  To edit file header blue arrow )

  • Click on the edit button and the header script is loaded into the editor. Modify it to meet your requirements.
  • When ready, quit the header editor by clicking the same button.
  • Find more about the header syntax at the end of this article.

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.

  • The origin corner X0,Y0
  • Data direction (The direction in which the pixels slices are taken from the work canvas and converted to GLCD data, for example in slices or in full canvas height or full canvas width. A slice is 8 pixels in monochrome mode and 2 pixels in 4bpp grayscale mode)
  • The Endianness (Most Significant Bit is first or last)
  • Special settings

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.

GLCD Data array output options

Bitmap2LCD is a tool for programming small Graphic LCDs in embedded systems.

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)

bitmap2LCD GLCD to binary file 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..)

bitmap2LCD GLCD to text file output

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”.

Use the file explorer’s project path in Bitmap2LCD

Bitmap2LCD is a tool for programming small Graphic LCDs in embedded systems.

At the top left side of the file explorer, you can set your 5 different project folders.

You can differentiate Graphic files, Output files ,Documentation files, Fonts files and Touch Panel files.

When you’ve selected the folder in the file explorer, click the blue, red, yellow, green or orange icon (fig1. blue arrow at the bottom)  corresponding to the files family, in order to set the path.

Later on, you can either click on one of the the direct links (red arrow) for unfiltered files lists or on the file family (for example upper blue arrow) to display a filtered list. (This files filtering option can be disabled or enabled at the bottom of the filters menu)

 

 

New window layouts and menus ( since Bitmap2LCD v2.0 )

Bitmap2LCD is a tool for programming small Graphic LCDs in embedded systems.

From v2.0 upwards, the work canvas window ( pixel painting grid ) became smaller than before and the former large menu at the top of the main window, has been replaced by a main menu (blue arrow) and sub-menu (red arrow ) structure. Sub-menu content just changes depending on what’s selected on Main menu.

A new fast access menu is accessible by right-clicking at the down right corner work canvas button or on the horizontal and vertical scrollbars. (Green arrows)

When the Work Canvas Window background is red, it means that an active area selection is still active ! This area can be moved by a mouse drag, and then pasted at the right position.

The pixel color can be selected by right- ( or left-) clicking on the foreground/background color icons (On the fig. below black=FG White =BG).

Foreground and background colors, can also easily be swapped.
