I need to use the cam in processing but it's already used by OSC Face and it seems to be a problem. Is there a way to make one cam used by 2 softwares? In this case, Processing and OSC Face?

Thank's all.

I'm would like to use the build-in java class  java.io.File to collect the number of .jpg in my data folder.

When I want to use it in my code, to set a int, I got a message error "Cannot convert int[] to int"

I want to convert it to a int because my code'd display randomly one of the jpg from my data folder.

The error comes from line 21.

1. void setup(){
2. 
   
4.     // have a look in the data folder
5.     java.io.File folder = new java.io.File(dataPath(""));
6. 
   
7.     // this is the filter (returns true if file's extension is .jpg)
8.     java.io.FilenameFilter jpgFilter = new java.io.FilenameFilter() {
9.       public boolean accept(File dir, String name) {
10.         return name.toLowerCase().endsWith(".jpg");
11.       }
12.     };
13. 
    
14.     // list the files in the data folder
15.     String[] numberofpics = folder.list(jpgFilter);
16. 
    
17.     // get the number of jpg files
18.     println(numberofpics.length + " jpg files in specified directory");
19.     
20.     int numberofpics_int = int (numberofpics);
21.     xPic = numberofpics_int;
22.     
23.     //Pic loading
24.     Pic = random(1,xPic);
25.     int PicFragNumber = int (Pic);
26.     img = loadImage("Pic_" + PicFragNumber +".jpg");

Thank's a lot.

is there a way or a library or anything to read the original frames rate of a gif?

I have thousands of gif animation files to display and they all seem to have different rates.

Thank you all.

I try to code a program which display successively thousands of pics and hundreds of Gif.

I cant' declare them all so a float load one randomly while the previous one is displaying.

The part with the pics only worked just fine.

I tried to add the same program for diplaying Gif too (randomly choosing between a Gif and a Pic) and it just doesn't work

The Gifs are displaying fine (successively and randomly) but one pic (and always the same each time I launch the program) is displaying too, while the gifs are running.

So two questions here.

Why it's always the same Pic and the float isn't working?

How do I stop the Pic display function while the Gif is looping.

Here is my code.

Thank's a lot

I got a problem on a project.

I want to display some gif randomly and repeat each x times.

Displaying them randomly isn't a problem. I managed to do it with jpeg so it won't be hard I think.

The problem is the repeat program.

I'm using the library gifAnimation

file://localhost/Users/Romee/Documents/Processing/libraries/gifAnimation/docs/index.html

and I think that the amount of repeats is set into the gif himself

when I use the methods 

int getRepeat()

it repeat itself perpetually as if my gifs were set for infinite repeats.

Does anyone knows how to set (or reset more precisely) the number of repeats into the gif?

I'm not sure it can be done with processing. Photoshop maybe?

Thank's a lot!

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!!
