Set Image output from extension

[jean-marc_Latour]

Hello all
This is my new extension.
Description

This extension allow you to edit image files and obtain a new image file
I did it because when i wanted to dark an image and blur it befor to set it in layer
I have only found 3 simples extensions :

AICODE - ImageUtil

[Free] BlurBackground with image. My 11th extension

but edited image was not save in file and was not really background image
so th only way was to use

[F/OS] 🖼️ ViewUtil: Convert a component into an image!

Introduction An extension that creates an image of a visible component. This can be useful to screenshot components with particular information that needs to be stored, such as an arrangement that contains a bill, or images of buttons for other buttons. Thanks to @Jerin_Jacob for the Convert component to image, I took inspiration from his extension. Release date: 2022-03-23T03:30:00Z (UTC) Package name: com.gordonlu.viewutil.aix Version: 4 …

the probem was it spend lot of time And i didn't succed to do it asynchronous with

[Free] Async Procedures | Extension

With this extension, you can edit image file and get it as an image file
you can also scale it to reduce it and go faster
you can do several editions and get result in a file
You can do all this async in order to not freeze your app

Thanks to Justus Raju because i started with his extension
https://mit-cml.github.io/extensions/data/extensions/ai.cdk.justus.ImageProcessor.aix
I corrected some little bugs and completed it, many thanks

I hope it will be helpful for some of you

i 'd like to use AI loaded image image but i don't succed to get it in my code:

    @DesignerProperty()
    @SimpleProperty(description = "Sets the Image ")
    public void SetImage(Bitmap bitmap) {
        this.globalBitmap = bitmap;
    }
	*/

this give me an error:
java.lang.IllegalArgumentException: Cannot convert Java type 'android.graphics.Color' to Yail type

i tried this

but mx.gif is just a string so i don't know how to put this image in "this.globalBitmap"

@jean-marc_Latour

i 'd like to use AI loaded image image but i don't succed to get it in my code:

somebody could help me with this ?

[Kevinkun]

@jean-marc_Latour

use AI loaded image image

what's this meaning?

[jean-marc_Latour]

@Kevinkun

what's this meaning?

and then i want to use it in my extension
I rtrid this:

 @DesignerProperty()
    @SimpleProperty(description = "Sets the Image ")
    public void SetImage(Bitmap bitmap) {
        this.globalBitmap = bitmap;
    }
	*/

it it's not an Bitmap it seems to be a String "mx.gif" ...
I don't know how to do to get it in Bitmap to edit it...

[TIMAI2]

public void SetImage(String filePath) {
    Bitmap bitmap = BitmapFactory.decodeFile(filePath);

[jean-marc_Latour]

well...
i tried this

    @DesignerProperty()
    @SimpleProperty(description = "Sets the Image ")
    public void Image(String image) {
		this.globalBitmap = BitmapFactory.decodeFile(image);
		this.globalBitmapSet=true;
    }
	@DesignerProperty()
    @SimpleProperty(description = "")
	public String test(){
		if(this.globalBitmap!=null)return "ok";
		else return "null";
	}

but it return null.......

[TIMAI2]

You have to write the "bitmap" back out to file once you have "modified" it.

final FileOutputStream stream = new FileOutputStream(output,false)) {
        //modify bitmap here
        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, (OutputStream) stream);
        stream.close();

        File file = new File(output); //new filename with path

[jean-marc_Latour]

Yes of course ! i have already a procedure like this,
but i wrote this

@DesignerProperty()
    @SimpleProperty(description = "")
	public String test(){
		if(this.globalBitmap!=null)return "ok";
		else return "null";
	}

because after

 @DesignerProperty()
    @SimpleProperty(description = "Sets the Image ")
    public void Image(String image) {
		this.globalBitmap = BitmapFactory.decodeFile(image);
		this.globalBitmapSet=true;
    }

when i try to modify this.globalBitmap i get an error " attempt to invoke virtual methode 'int android.graphics.Bitmap.getWidth() on a null reference object reference"...
it seems there is nothing in this.globalBitmap

[Patryk_F]

This should work in the compiled APK. If you are testing in companion you must use decodeFile. But you need to get the full path to the file, because the gif file block in app inventor returns only the file name, without the path.

@DesignerProperty()
    @SimpleProperty(description = "Sets the Image ")
    public void Image(String image) {
        AssetManager assetManager = context.getAssets();
        InputStream inputStream = assetManager.open(image);
		this.globalBitmap = BitmapFactory.decodeStream(inputStream);
		this.globalBitmapSet=true;
    }
	@DesignerProperty()
    @SimpleProperty(description = "")
	public String test(){
		if(this.globalBitmap!=null)return "ok";
		else return "null";
	}

[TIMAI2]

and bitmapfactory only works with JPEG/PNG/WEBP.

[jean-marc_Latour]

@Patryk_F

This should work in the compiled APK.

yes i use compile APK but it doesn't works...

@Patryk_F

you need to get the full path to the file

that is my problem: how can i find full path ?
i can't see any file "mx.gig" with my file explorer...

[Patryk_F]

@jean-marc_Latour

yes i use compile APK but it doesn't works...

Have you tried this code? Try the same code but with a PNG file, as Tim mentioned.

[jean-marc_Latour]

@Patryk_F

AssetManager assetManager = context.getAssets();

it seems i must import class, but i dont know which one,
i tried import android.AssetManager; but no success...sorry, i'm newbee
