ft81x load_assets and cmd_loadimage problem

[rayman]

hi @all

i use an ft812 with gd3-lib ...

load_assets and cmd_loadimage in the same programm dosn't work

the asset is 189644byte, the image is a 800x400 background-image.png 129660byte

assets 185k
image 126k
sum    311k

the ft812 has 1mb ram, where is the problem

follow code broken bg-image


   GD.begin(~GD_CALIBRATE);
   GD.cmd_setrotate(0);
   LOAD_ASSETS();
   GD.BitmapHandle(15);
       GD.cmd_loadimage(ASSETS_END, 0);
       GD.load("bg001.png");
the follow has broken assets


   GD.begin(~GD_CALIBRATE);
   GD.cmd_setrotate(0);
   LOAD_ASSETS();
   GD.BitmapHandle(15);
       GD.cmd_loadimage(-1, 0);
       GD.load("bg001.png");
who overwrites the memory when and why

[rayman]

... if i pack everything into a asset

$> gd2asset -o assets.h -f def.bin BIG_NUMBERS/0.png BIG_NUMBERS/1.png BIG_NUMBERS/2.png BIG_NUMBERS/3.png BIG_NUMBERS/4.png BIG_NUMBERS/5.png BIG_NUMBERS/6.png BIG_NUMBERS/7.png BIG_NUMBERS/R.png  graph/teufel.png sym/bat.png sym/sat.png bg001.png
Assets report
-------------
Header file:    assets.h
GD3 RAM used:   957644
Output file:    def.bin
File size:      64505

and use the follew testcode

on startup
   GD.ClearColorRGB(BLACK);
   GD.Clear();
   LOAD_ASSETS();
   ...

in main-loop
   GD.ClearColorRGB(BLACK);
   GD.Clear();
   GD.Begin(BITMAPS);
   GD.Vertex2ii(0, 0, BG001_HANDLE);
   ...
   ...
   GD.Begin(BITMAPS);
   GD.Vertex2ii(400-43, 240-64, SAT_HANDLE);


i have this result

Could you attach images? In the images for example with GD2Assets the option;


gd2assets -f xxxx.gd2 -o xxxx.h mypics.png,format=ARB4
After;


   GD.begin();
   LOAD_ASSETS();
   GD.BitmapLayout(ARGB4, 2 * 64, 64); // override the bitmap layoutinsert code here

all images for my gd2asset call in the attachment ...images.tgz (137.66 KB)

thx for your time

The "windows-size" is it not the same that "GRAM-size"

The asset converter bring two sizes:

GDX RAM   (FT8XX file size)

File size (Windows file size)
The corret size to consider in account is RAM-size, so you must combine RAM-size of background image and RAM-size of your prefer group of assets.

Remember this gold Asset key: the file name of each image inside the group of assets, must be start with a letter.

[rayman]

i have put all images in one asset for test, the result is

Header file: assets.h
GD3 RAM used: 957644 <-- 957644 < 1mb
Output file: def.bin
File size: 64505

and the problme is the same...see my previous post

Well the png images of 800x480 on FT81X maybe have some limit on the GRAM. In order to avoid such limitation, we can split such kind of images, and introduce in the asset group.


int PXL=-390, PXD=400-PXL, SpeedX=40, XMov=1;

void loop() {
 GD.Clear();  
  GD.Begin(BITMAPS);

  if(XMov==1){
              PXL=PXL+SpeedX;
              PXD=400-PXL;
              if(PXL>=0){XMov=0;}
              }

 GD.SaveContext();
   GD.VertexTranslateX(16*PXL);
   GD.Vertex2ii(0, 0, 12);      //left panel
   GD.Vertex2ii(360, 170, 0);
   GD.SaveContext(); GD.ColorRGB(255,0,0);  GD.Vertex2ii(390, 110, 9);   GD.RestoreContext();
   GD.SaveContext(); GD.ColorRGB(0,15,255);  GD.Vertex2ii(390, 340, 10);   GD.RestoreContext();
   GD.SaveContext(); GD.ColorRGB(0,255,0);  GD.Vertex2ii(260, 215, 11);   GD.RestoreContext();    
 GD.RestoreContext();

 GD.SaveContext();
   GD.VertexTranslateX(16*PXD);
   GD.Vertex2ii(0, 0, 13);      //right panel
 GD.RestoreContext();

GD.swap();
}

thx, i will try the same times

[tftlcdcyg]

In the setup

void setup() {
 GD.begin();

 LOAD_ASSETS();
}

[rayman]

thx for help, works now ...

can i share my background and reflect in the middle of screen ?
that would save the half of memory ... or is that a bad idea because of the draw speed in main loop

thx
