Reverse engineering : Convert an existing Data Array (or Hex File) to a Bitmap

Update V3.7e , monochrome only

Want to convert 8 bit GLCD data array from an old project to a 16 bit GLCD data array in a new project ?

Want to recover the image from of an old GLCD data array source ?

 

bitmap2lcd-glcd-array-to-bitmap

  • Load a source into Text editor ( Red arrow )  or click on source file inside Text editor
  • Data array inside Text Editor ( Green arrow )
  • Import Data to Graphic  ( Blue Arrow )

For monochrome GLCD data arrays of 8, 16 and 32 bit – bytes/words – , it is possible with bitmap2LCD !

Set your work Canvas Height and Width to a compatible size with the number of data in the array loaded in the text editor, set the byte word  Width to 8 16 or 32bits (in the output main menu) , select the data direction (horizontal or vertical) and click one of the import Data Array buttons. If it matches with the data count, the Work Canvas will show the graphic.

For example in a file an array of 2560 bytes ( 0x00 – 0xFF )

( Width * Height ) Pixels per byte =  (160 * 128) / 8 = 2560 bytes

Import the array into the work canvas and save the work canvas as bitmap.

Import System Chars into the Font Editor

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

Import System Chars into the Font Editor

Update V3.7e , Standard Edition

bitmap2lcd-glcd-font-menu

Let’s see how we can export selected characters out of a Windows System font into the Font Editor of Bitmap2LCD :

  • Create a GLCD Font Script by clicking the Main menu item or the Font Panel Button (blue arrow)
  • Choose a Font Name and define its size

bitmap2lcd-editable-font_1

  • In the “Ascii Grid“, select the chars you want to export, here for example A, B and C  (red arrow)
  • In the menu, click on item ” Start editable font Export > Editable (Translate LCD Font Script to an Editable Font (green arrow)

bitmap2lcd-editable-font_2

The “editable font” has been created. It is an Editable Font File (EFF) and an associated GIF file, which is the catalogue of char bitmaps. Both files are located in the Fonts folder.

  • Quit Font Script Creator mode and Open editable (orange Arrow)

bitmap2lcd-editable-font_3

In this example, the selected font name and font size were Aria Unicode MS and 20, in this case the filename of the file will be Arial Unicode MS_20Editable_Font.EFF

bitmap2lcd-editable-font_4

The patterns of theses 3 chars (green Arrow) can now be freely edited.

Example 2

In the first example above, the height of the chars is 25 pixels.

This time, we want to limit the Size of chars in Height and in Width and export a Fixed Size Font.

  • Change the first 3 Parameters (purple arrow) and you will see a red frame in the char View (green arrow)
  • Export To editable (blue arrow)

bitmap2lcd-editable-font_5

  • You get these editable chars

Anti-Aliasing and Smoothing of GLCD images and fonts

Anti-Aliasing and Smoothing of GLCD images and fonts

Anti-aliasing or “font smoothing” is a process to make your images look smooth and your text more readable.

Anti-aliasing or font smoothing is a technique to make flat color images and text look smoother on grayscale GLCD screens. The font generator in the Bitmap2LCD tool features font smoothing for 16 grayscale OLED GLCD (4 bit pixel depth)
A graphic liquid crystal display shows an image in bitmap mode. It means that every image is really a bunch of tiny little squares that make up the image. In other words, fonts on monochrome GLCDs or monochrome fonts displayed on grayscale GLCDs, can’t display chars with smooth curves. With anti-aliasing, the curve is created with squares of color that are shaded darker or lighter depending on how much of the curve would take up that square. For instance, if a portion of a curve takes up 10% of a pixel, that pixel would be shaded with 10% of the color saturation of the curve, in fact in case of a 16 grayscale level GLCD, the nearest gray level of the 10%

Anti-aliasing Pros and Cons

Pros
  • Makes fonts look smoother
  • Rounded edges look round
  • Type is easier to read (for some) because it looks more like what printed type looks like
  • Some people feel it’s prettier

Cons

  • Small fonts become too fuzzy to read
  • Sharp edges may be fuzzy and not precise
  • You can’t print anti-aliased text as it comes out blurred
  • Images are generally larger
  • Type is easier to read (for some) because the blurring is reduced and the fonts are clear

Note : This post summarizes information found here and there on the web

Creating A GLCD Font

Creating A GLCD Font

Standard Edition , Update V3.7c

Bitmap2LCD can generate two different types of GLCD Fonts :

  • System Fonts : Fonts of the Operating System, like .TTF (True Type Fonts) , .FON
  • Editable Fonts : Fonts you can edit yourself (modifying the pixels) from a system font source, or Fonts you can create from scratch.

There are ANSI Fonts (system) , Unicode Fonts (system) and Editable Fonts (custom)

bitmap2lcd-font-menu

Choose the main menu GLCD Fonts tab, and click Enter Font Script Mode item to enter Font Creation Mode

Data Setting Parameters are located in Data tab. You can edit the values by clicking on parameter value of the parameter list, only when in Font Script Mode and with Standard Edition.

At the top of the font panel , the caption includes [Font Script Mode] when in Font creation Mode. Use the Door Icon exiz Button to exit this mode when willing to quit.
