Hi all!

I'm as new here as in programming :)

I created a small program for my degree project. I'm in an art school.

It's a program that loads pictures like a slideshow, very quickly.

I've got thousands of pictures with different sizes.

How could I say

if the picture width is bigger than than the screen width, width pictures == screen width,

f the pictures height is bigger than than the screen height, height pictures == screen height,

I'm sure it so simple but I'm a bit of a Newbee :)

Thank's all

Here is my code.

PS: I'm sure it could be optimized so if you see anything that could be coding better, PLEASE tell me!!

Brainwashing

Correction: romée by basile

PImage img;

String[] files;

int timer;

float a ;

int fragNumber;

void setup() {

size(1300,760);

float a = random(0,1327);// a est une valeur au hasard comprise entre les deux valeurs données (n'apelle pas tes images "0001" mais "1");

int fragNumber = int (a);//fragNumber est l'arrondi de a (10,55 --> 11)

img = loadImage("pic_" + fragNumber +".jpg");

println(fragNumber);

timer=0;

}

void draw() {

background(255);

if(timer==0)

{

smooth();

imageMode(CENTER);

image(img,650,380);//Si tu veux leur donner à toute une taille commune (les adapter à la fen^tre par ex:

// il te suffit de mettre image(img,0,0,largeur,hauteur);

}

else if(timer==1)

{

a = random(0,1327);

int fragNumberPlus=int (a);//fragNumberPlus est l'image qui charge pendant ce temps (une autre épreuve de "a")

img = loadImage("pic_" + fragNumberPlus +".jpg");

println(fragNumberPlus);

delay(130); //this decides how long an image should be displayed

}

timer=(timer+1)%2;

}

(when you post code, the comments should be in english)

so you want to change the size of your frame, according to the size of your current image? or reverse?
the following code changes the size of the frame ( i didnt make any comments, because the code is quite simple):

press the spacebar the see another image

PImage img;
int img_index = 0;
String img_list[] =
{
"http://processing.org/img/cover/onefive.png",
"http://processing.org/img/processing_cover.gif"
};
void setup(){
size(400, 400);
img = loadImage(img_list[img_index]);
resizeMe(img.width, img.height);
}
void draw(){
image(img, 0, 0);
}
void keyReleased(){
if( key == ' '){ //press SPACE BAR
img_index++;
if( img_index >= img_list.length ) img_index = 0;
img = loadImage(img_list[img_index]);
resizeMe(img.width, img.height);
}
}
public void resizeMe(int size_x, int size_y){
int dif_x = frame.getWidth() - width;
int dif_y = frame.getHeight() - height;
frame.setSize(size_x + dif_x, size_y + dif_y);
size(size_x, size_y);
}

Hi Thomas,

Thank you for responding so quickly.

Excuse me for the comments but I tough the code was really easy so it was useless to translate them.

I can do if you want.

I want to use the program in full screen so it's the size of the pictures which change if they are bigger than the size of the frame (the size of the frame is the size of my screen).

Thank you so much for helping me!

Anyone got the answer?

Just want to resize my pictures automatically if they don't fit in my frame.

Please, I'm out of idea...

Big Thank's

You can find the answer on how to resize pictures in the reference: image resize

PImage img = loadImage("jelly.jpg"); // load
if (img.width>screen.width) { img.resize(screen.width,0); } // conditional resize width
if (img.height>screen.height) { img.resize(0,screen.height); } // conditional resize height
imageMode(CENTER); // set image mode to centered
image(img, width/2, height/2); // display image in center of the sketch

Also, you can use screen.width and screen.height in your setup's size function.
