Converting JPG to Bitmap with-out changing size

I save .jpg image in my cache folder. Image is 4,032x3,024 (24-bit color) that weights 3.35MB. Now, I wanted to convert this very same jpg to bitmap.

I used code:

val bitmapFromJpg = BitmapFactory.decodeFile(jpgFile.absolutePath)

But what surprised me was that it automatically changed the orignal size of the image - 1,024x768 (32-bit).

Even with

val opts = BitmapFactory.Options()
opts.inSampleSize = 1
val bitmapFromJpg = BitmapFactory.decodeFile(jpgFile.absolutePath, opts)

result is the same...

Why is this happening and how to avoid it (I want to keep original size)?

Solution

  • Yes you can change inScaled

    By default it's value is true, try this code

    val opts = BitmapFactory.Options()
opts.inSampleSize = 1
opts.inScaled = false
val bitmapFromJpg = BitmapFactory.decodeFile(jpgFile.absolutePath, opts)

    I tested this my jpg image size(HeightXWidth) was 600X600 and after converting to bitmap it remain same 600X600.
