Android Question when converting the image , it is not captured completely

Is this because of the image, I tried to convert it to more bitmap through black and white shown in the right of the image, but how is it initialize ? Or maybe i need to save image the file in Temp file and load it again so that changes of Flip etc are permanently made. Then the conversion is done

Sorry, but I do not understand what exactly you want to do.
You have a SeekBar in your layout with Visible set to False, therefor it is not displayed.
I Set Visible to True, and the SeekBar event does not work.
Because the event name must be ValueChanged and not ValueChange !!!
I leave it up to you to correct it.
Then your original image is already black and white, so I do not understand the logic.

i mean that, mabye it need a process before it in order to catchh the full

Sorry, if it might sound a bit rude.
But you need to think a bit about of what you are doing.
The size of your image is 255 * 255 pixels.
This means that you need 255 characters for each line !!!
How many characters can you put horizontally in your EditText view.
In the test project, the image is not displayed completely because I limited it intentionally to limit the number of iterations!
Maybe you missed the comment in the other thread: For testing I reduced the loop.
In the image of your previous post you display about 40 characters per line, out of 256 !?

I just made some changes to see what happens.
To see full lines in the EditText I had to set the TextSize to 1 !!!
Then, the number of characters exceeds the max authorized number.
So I limited the number of lines.
Then, in your image not all supposed black pixels are really black and bot all white pixels are really white.
This means that your test is wrong !
Up to you to improve it.

Attached the test project.

Again, what is the purpose, is it just for fun or something else ?

Yes, as I indicated in the image, it must be converted to black and white again in order to obtain a pure pixel, the result is the same as visual basic, for something else it is output to a microcontroller

Could this maybe help....

As I already told you, your test is wrong !
Attached a new version.
It uses the same BlackeAndWhite routine, you used for the right image, which returns a BitmapCreator instead of a Bitmap.
In what format do you want to send the image to the microcontroller?

In what format do you want to send the image to the microcontroller?

only data to arduino in hex format (convert to base) and (convert from base)

First, try to do it on your own.
I have never done it, so I would need to do the same as you could do, search and test.
In the BlackeAndWhite routine you know for each pixel if it is black or white.
So, you can create the message for the Arduino in the format you need.
