Convert Bitmap with cells?

[lightcalamar]

With tools gd2asset convert.
After this post link need more than 15 handles,  please How to convert this image with 2 cells?




My code convert this;

gd2asset -o logo.h logo.jpg,format=ARGB4
Only one cell. why?

[jamesbowman]

#include <EEPROM.h>
#include <SPI.h>
#include <GD2.h>

#include "logo.h"

void setup()
{
 GD.begin();
 LOAD_ASSETS();
 GD.BitmapLayout(ARGB4, 2 * 64, 64); // override the bitmap layout
}

void loop()
{
 GD.cmd_gradient(0, 0, 0x103010, 480, 480, 0x101030);
 GD.Begin(BITMAPS);
 GD.Vertex2ii(100, 100, 0, 0);
 GD.Vertex2ii(200, 100, 0, 1);
 GD.swap();
}

You can do it like this. The call to BitmapLayout tells the GPU to "split" the bitmap into cells of 64x64 pixels.

Thanks you James, Works fine.
One question. I want to now put two images this for example;


and ;


My code asset-converter this;

gd2asset -o logos.h logo.jpg,format=ARGB4 logo2.jpg,format=ARGB4

My Code Arduino MEGA is;


#include <EEPROM.h>
#include <SPI.h>
#include <GD2.h>

#include "logos.h"

#define PDNPin 8       // Señal P.O.R. TFT FT800

void setup()
{
   pinMode(PDNPin, OUTPUT);       // CONTROL P.O.R. Power On Reset
   digitalWrite(PDNPin, HIGH);    // Pantalla FT800 comparada
   delay(20);                     // en http://HotMCU.com
   digitalWrite(PDNPin, LOW);     //           |
   delay(20);                     //           |
   digitalWrite(PDNPin, HIGH);    //           |
   delay(20);                     //           |
 
   GD.begin();
   LOAD_ASSETS();
   GD.BitmapLayout(ARGB4, 2 * 64, 64); // override the bitmap layout
}

void loop()
{
 GD.Clear();
 GD.cmd_gradient(0, 0, 0x103010, 480, 480, 0x101030);
 GD.Begin(BITMAPS);
 GD.Vertex2ii(100, 100, 0, 0);
 GD.Vertex2ii(300, 100, 0, 1);
 GD.End();

 GD.Begin(BITMAPS);
 GD.Vertex2ii(200, 200, 1, 0);
 GD.Vertex2ii(300, 200, 1, 1);
 GD.End();
 
 GD.swap();
 
}
This obtained ;

You can help me?
Thanks !

Sure, in this example you now have two handles (LOGO_HANDLE and LOGO2_HANDLE). You need to change the layout for each handle, like this:

GD.BitmapHandle(LOGO_HANDLE);
GD.BitmapLayout(ARGB4, 2 * 64, 64);
GD.BitmapHandle(LOGO2_HANDLE);
GD.BitmapLayout(ARGB4, 2 * 64, 64);

Infinite thanks James, this be a result;





#include <EEPROM.h>
#include <SPI.h>
#include <GD2.h>

#include "logos.h"

#define PDNPin 8       // Señal P.O.R. TFT FT800

void setup()
{
   pinMode(PDNPin, OUTPUT);       // CONTROL P.O.R. Power On Reset
   digitalWrite(PDNPin, HIGH);    // Pantalla FT800 comparada
   delay(20);                     // en http://HotMCU.com
   digitalWrite(PDNPin, LOW);     //           |
   delay(20);                     //           |
   digitalWrite(PDNPin, HIGH);    //           |
   delay(20);                     //           |

 
   GD.begin();
   LOAD_ASSETS();

   GD.BitmapHandle(LOGO_HANDLE);
   GD.BitmapLayout(ARGB4, 2 * 64, 64);
   GD.BitmapHandle(LOGO2_HANDLE);
   GD.BitmapLayout(ARGB4, 2 * 64, 64);
}

void loop()
{
GD.ClearColorRGB(0, 0, 0);
// GD.Clear(1, 1, 1);
 GD.Clear();
 /*
 GD.cmd_button(0, 0, 479, 45, 30, 0, "Estacion Meteo");

 GD.Begin(LINES);
 GD.Vertex2ii(0, 50, 20, 0);
 GD.Vertex2ii(480, 50, 20, 0);
 GD.Vertex2ii(0, 54, 20, 0);
 GD.Vertex2ii(480, 54, 20, 0);
 GD.End();
// GD.End();
*/

// GD.cmd_gradient(0, 0, 0x103010, 480, 480, 0x101030);
 GD.Begin(BITMAPS);
 GD.Vertex2ii(100, 100, 0, 0);
 GD.Vertex2ii(300, 100, 0, 1);
 GD.End();

 GD.Begin(BITMAPS);
 GD.Vertex2ii(200, 200, 1, 0);
 GD.Vertex2ii(300, 200, 1, 1);
 GD.End();
 
 GD.swap();
 
}



This I seek. Take more than 10 days to find a solution ... You give. To give you infinite thanks again. Thomas.
