  thanks @Gordon, it's working with r100 :)

  Hello @Gordon

  i'm testing code with pcd8054 lcd.

  the example works well with 2.04 firmware, but not with the 2.05 firmware. (i updated to try the scale factor feature on Font).
  If i downgrade to 2.04 it works again...

  SPI1.setup({ sck:B3, mosi:B5 });
  var g = require("PCD8544").connect(SPI1, B6 /*DC*/, B7 /*CE*/, B8 /*RST*/, function() {
    g.clear();
    g.drawString("Hello",0,0);
    g.drawLine(0,10,84,10);
    g.flip();
  });

  Thanks @NebbishHacker for the code.
  the slanted font need a different width to have a good kerning.
  I use a fixed size font of 9x8 px.
  i had an array to specify the with of each letter for a correct kerning

  //                    a b c d e f g h i j k l m n o p q r s t u v w x y z
  var largeurLettres = [3,0,0,0,6,5,4,0,3,5,5,3,8,0,0,0,5,5,0,4­,0];
  function drawStringSlanted(text, x, y) {
    var largeur = 0;
    for (var char of text) {
      g.drawString(char, x, y);
      index = char.charCodeAt(0);
  // 65 is my offset in the array for lowercase (i do  not draw all the font) and 32 for my first char (space)
      x += (largeurLettres[index-(65-32)]+ 2);
    }
  }

  thanks @NebbishHacker, but the question is now to overlap on previous drawn letter.
  Cause with a slanted font the width's letter is not the place for the next letter as in comment #21

  ok!
  is there a simplier way to draw?
  can i draw with drawString only one letter in an image?
  i prefer the way you use a font with a picture than use x, space and carrier return...to draw my font... it look like in Arduino.

  well and after using drawImage i suppose i have to paste the drawing with g.drawImage(img,0,0)?
  can i overlapping ?
  0+1 = 1
1+1 = 0
1+0 = 1
  ?

  in Photoshop it's call "product" mode. black is transparent (0), white is opaque (1)

  Thanks @gordon for you explanations

  In fact, I am really sad to have to abandon the ide in chromeApp, it was very practical and had fewer limitations than the online ide.
  Goog pretends to abandon techs that bring him nothing. they hit us regularly ... grr

  some other test

  The first pic is with a kerning of 2 px (as it should be)
  The second pic is with a 1 px space between letters (as it should not)
