B4J Question Read image file into array...

[rbghongade]

Dear friends,
Is there a way to read an image file (bmp/jpeg/tif) into an integer array? Tried to search in forum but did not get any clue. (Maybe I missed !)
Apology if the issue has been addressed earlier!

What is the reason for it? What are you trying to archieve?

Dear DonManfred,
I am planning to write some code for image processing using B4J, to be used by my students.

You can get the pixelsd of an Image with https://www.b4x.com/b4j/help/jfx.html#image_getpixel

Thanks DonManfred.
Is there any library required to be associated , since type Bitmap is not recognized.

The Imagetype in B4J is Image

Dear friends,
I was able to read an image into array of integers successfully (thanks to DonManfred and inakigarm), but now I want to write the processed data (array of ints) as an output image file,but am not quite getting it. Tried to use writetostream method but am not being successful.
