@paulgoux how to use the code ?
import java.io.BufferedWriter;
import java.io.FileWriter;
String outFilename = "out.txt";
void setup(){
// Write some text to the file
for(int i=0; i<10; i++){
appendTextToFile(outFilename, "Text " + i);
}
}
/**
* Appends text to the end of a text file located in the data directory,
* creates the file if it does not exist.
* Can be used for big files with lots of rows,
* existing lines will not be rewritten
*/
void appendTextToFile(String filename, String text){
File f = new File(dataPath(filename));
if(!f.exists()){
createFile(f);
}
try {
PrintWriter out = new PrintWriter(new BufferedWriter(new FileWriter(f, true)));
out.println(text);
out.close();
}catch (IOException e){
e.printStackTrace();
}
}
/**

void createFile(File f){
File parentDir = f.getParentFile();

}catch(Exception e){
e.printStackTrace();
}
}
try {

output.flush();
output.close();
}
catch(IOException e) {
println("It Broke :/");

As for video @noel has a video sketch.
Hi @paulgoux this code how to save image from ketai camera ?
You just have to set the fileoutput.img variable.
Ketai produces an image for the cam stream, simply called cam, so set img to cam.
I did not understand
Theres a variable in the fileoutput class called img. Thats what it uses to save. If you want to save something else such as the ketai class variable cam which is a pgraphics object then you have to set img to cam.
I meant in the imageSaver class
All img set to cam ?
What do you mean all.
Just write
fileOutput f = new fileOutput();
f.img = cam
This will have to be done in draw or img wont have the most recent camera image.
I can not find this or maybe I am still not following with you
Sorry again this needs to be the image saver.
But please look at the code ive shared.
class imageSaver{
Permission wstorage,rstorage;
Activity act;
PApplet p;
int counter = -1,maxImageCount;
boolean imageSaved,mdown;
String folderName = "MyImageFolder",fileName,ext,absolutePath;
String imageFile = "MyImage.jpg";
// see this variable is the one saved
PImage img;
File file,file2;
imageSaver(PApplet applet){
p = applet;
wstorage = new Permission(p,"WRITE_EXTERNAL_STORAGE");
act = p.getActivity();
getExt(imageFile);
};
imageSaver(PApplet applet,String s1, String s2){
folderName = s1;
imageFi
alternatively using the following sketch
import android.os.Environment;
import android.Manifest;
import android.content.pm.PackageManager;
import android.os.Build;
import android.os.Build.VERSION_CODES;
import processing.core.PConstants;
import android.app.Activity;
PImage img;
Activity activity;
boolean image_saved;
boolean permissions_granted;
// Folowing file name is the folder you save your image file in.
// If it does not exist it will be created automatically
String folder_name = "MyImageFolder";
// Folowing string is the name of your image file
// Be sure to include extension.
String image_file = "MyImage.jpg";
Permission wstorage,rstorage;
void setup() {
wstorage = new Permission(this,"WRITE_EXTERNAL_STORAGE");
rstorage = new Permission(this,"READ_EXTERNAL_STORAGE");
size(displayWidth, displayHeight);
background(0, 0, 200);
rectMode(CENTER);
rect(width/2, height/2, width, height/2);
textAlign(CENTER);
String str = "Click to save an image.";
textSize(12);
float twf = width/textWidth(str);
textSize(8*twf);
fill(0);
text(str, width/2, height/2);
//rather than setting img here you set it in draw
//img = get();
//img.save(
};
void draw() {
//note you have to set it to whatever your ketaicamera instance is called + ".cam"
img = ketai.cam;
if (image_saved) {
background(0, 0, 200);
fill(255);
text("Image saved.", width/2, height/2);
}
};
void mousePressed() {
saveMyImage(folder_name, image_file);
};
void saveMyImage(String sf, String tf) {
try {
String absolute_path = new String(Environment.getExternalStorageDirectory().getAbsolutePath());
File file = new File(absolute_path+"/"+sf);
//println(file);
if (!file.exists()) {
boolean success = true;
success = file.mkdirs();
if(success){
save(file+"/"+tf);
image_saved = true;
println("File saved successfully.");
println("Path",absolute_path,"File",file);
}
else {
println("no File");
println("Path",absolute_path,"File",file);
