Images

Do you know what the upper size of the bitmap can be? If I make it really small it works, but over a certain size it just shows as a black box. I haven't quite narrowed down the size that breaks.

well, bmp images are loaded into ram, so you need at least enough ram

Hello,

it seems that in the XLS file in the GamebuinoPalette.zip file describing the colors, PINK (from the source) is called MAGENTA.

Thanks, I'll fix that :)

Bonjour , j'ai une image bitmap mais je sais pas comment la mettre dans le programme.

The section "Flash Image" explains how to do that. If you are still confused, would you please mind saying more specifically where you are stuck?

comment savoir si on a une image uint8_t ou uint16_t?

In the conversion tool linked. if you specified "indexed" it'll be uint8_t, else it'll be uint16_t.

ca change quoi?

Indexed images use a palette, by default the gamebuino palette. They are smaller in size.

RGB565 images are basically full color.

l'ide me dit qu'il y a une erreur de compilation.

c moi dit:

# include <Gamebuino-Meta.h> 

const uint8_t myImgBuf [] = { 
   8, 8, // largeur, hauteur 
  1, 0, // frames 
  0, // boucle d'image 
  0xFF, // couleur transparente 
  1, // Mode couleur 

  0x07, 0x07, 0x07, 0x07, 
   0x70, 0x70, 0x70, 0x70, 
   0x07, 0x07, 0x07, 0x07, 
   0x70, 0x70, 0x70, 0x70, 
   0x07, 0x07, 0x07, 0x07, 
   0x70, 0x70, 0x70, 0x70, 
   0x07, 0x07, 0x07, 0x07, 
   0x70, 0x70, 0x70, 0x70, 
} 

Image myImg (myImgBuf); sur cette ligne ca me dit "expected ',' or ';' before 'Image'"

void setup () { 
  gb.begin (); 
} 

void loop () { 
   while (! gb.update ()); 
  gb.display.clear (RED);
 
  // dessine l'image 
  gb.display.drawImage (10, 10, myImg); 
}

C est parcequ il manque un ; juste avant Image ;)  

const uint8_t myImgBuf [] = { 
   8, 8, // largeur, hauteur 
  1, 0, // frames 
  0, // boucle d'image 
  0xFF, // couleur transparente 
  1, // Mode couleur 

  0x07, 0x07, 0x07, 0x07, 
   0x70, 0x70, 0x70, 0x70, 
   0x07, 0x07, 0x07, 0x07, 
   0x70, 0x70, 0x70, 0x70, 
   0x07, 0x07, 0x07, 0x07, 
   0x70, 0x70, 0x70, 0x70, 
   0x07, 0x07, 0x07, 0x07, 
   0x70, 0x70, 0x70, 0x70, 
} ; //<<<<<<<<<<<<<<<<<<<<<--------------- celui la de point virgule 

Il faut bien lire les messages d erreurs souvent ils aident bien :)
