Bitmap2LCD is a multi-window application and supports dual screen.

List of the windows : Main window, LCD Viewer, Configuration Settings, File explorer, Graphic and Editors Window, Tool menu, Work Canvas, Adjustments, Font Panel and internal Web Browser.

You can show or hide (minimize) the windows, move them to the secondary monitor.

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)

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

Converting a bitmap to GLCD data.

Start   Export WORK CANVAS Graphic To a DATA ARRAY inside the Text Editor

Start HEX   Export WORK CANVAS graphic to Data inside the HEX Editor / BINARY file

Start Selected Export a selected area of the WORK CANVAS To a Data Array inside the TEXT EDITOR

Bitmap2lcd export graphic

Start a Graphic To Data conversion (fig 9. red arrow)

Your hexadecimal file appears in the Text editor, formatted according to the defined configuration settings. (fig 10)

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

Fig 14 )

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

  • The Text Field Editor
  • The single Line Text editor

Example of using the single Line Text Editor, text can be moved and pasted with paste

Working in Vector Mode (GLCD Library)

Using GLCD library functions like GLCD.rect(x,y,h,w) or GLCD.GotoXY(x,y) and similar :
