Bonsoir, j'ai un soucis avec la fonction ulLoadImageFileGIF.
Je n'ai aucune erreur lors de la compilation mais je n'arrive pas a faire fonctionner la rom...
Voilà la source : /*
test
*/
#include <ulib/ulib.h>
#include "james.h"
#include "banjo.h"
//Our image contains 3 frames, one next to the other vertically, and 32 pixel wide.
#define FRAME_HEIGHT 32
//Files stored in RAM.
UL_VIRTUALFILENAME ram_names[] = {
{"banjo.gif", (void*)banjo, (int)banjo_size, &VF_MEMORY}
};
int main()
{
UL_IMAGE *imgJames, *imgBanjo;
int animStage = 0, frameNumber = 0, color = 0;
int i, j;
//The frame numbers that will be used for animations
const int animPositions[] = {0, 1, 2, 1};
//Initialize µLibrary
ulInit(UL_INIT_ALL);
//Initialize the graphical part
ulInitGfx();
//Initialize the text part
ulInitText();
//We will use the touchpad this time
ulSetMainLcd(0);
//Use bright pink as a transparent color
ulSetTransparentColor(RGB15(31, 0, 31));
{
//We load our James character image. Note that the format is PAL4 (16 colors). It is enough for our image but may not for others.
imgJames = ulLoadImageFilePNG((void*)james, (int)james_size, UL_IN_VRAM, UL_PF_PAL4);
imgBanjo = ulLoadImageFileGIF("banjo.gif", 0, UL_IN_VRAM, UL_PF_PAL8);
}
ulDisableTransparentColor();
//Define the image center, so that the stylus will control the center of the image. By default, images are specified by their top-left corner (that's the fastest). Usually you should not have to change the image center except for rotation.

imgJames->centerY = FRAME_HEIGHT / 2;
while(1)
{
//Read keys
ulReadKeys(0);
color++;
if (color==25) color = 0;
//We place our character to the same position as the touchpad stylus, making it follow it
imgJames->x = ul_keys.touch.x;
imgJames->y = ul_keys.touch.y;
frameNumber++;
//Each 8 frames, we increment the frame stage counter, so that we display the next frame
if (frameNumber % 8 == 0)

for (i=0;i<SCREEN_WIDTH;i+=imgBanjo->sizeX) {
ulDrawImageXY(imgBanjo, i, j);
}
}
}
//Set up the sprite part to draw only the desired image part. We could do it by ourself using the offsetX0, ... members.
ulSetImageTileSize(imgJames,
0, //Image frames are aligned vertically, so we always begin to the left
FRAME_HEIGHT * animPositions[animStage], //Top position: animPositions defines the frame numbers in the image for each animation step (0, 1, 2, 1). Each frame is FRAME_HEIGHT tall, so we just have to multiply to get the actual position of the frame on the image!
imgJames->sizeX, //Every frame takes the entire image width
FRAME_HEIGHT); //Height of a frame
//Draw our character on the screen!
ulDrawImage(imgJames);
//End the drawing
ulEndDrawing();
//Wait the VBlank (synchronize at 60 fps)
ulSyncFrame();
}
return 0;

Voilà... Brunni please help! :cry:
