Fails to optimize an image in assets, Android 10 companion, using // ?

[Kumaraswamy]

Sorry, I don't think it can optimize images from assets

[TIMAI2]

works with full path:

/storage/emulated/0/Android/data/edu.mit.appinventor.aicompanion3/files/assets/

[Kumaraswamy]

I will fix the issue soon. Thanks

[TIMAI2]

That said does a good job, optimised a 1.9mb image file to 55kb. which looks fine on a phone screen.

Could you add an option to retain the original file name and append -compressed (or better -opt) to it,
or option to name the compressed/optimised file?

[Kumaraswamy]

So you mean like :

if(append)

the file name should be : "compressed" + orginal name.
Am I right?

@Kumaraswamy

to optimize images and reduce their size with loosing very little details

What does optimized mean? Original: left, opt: right

[Patryk_F]

This looks like compression with a large loss of quality.

[Anke]

No wonder:

[Patryk_F]

What is the resolution of both images?

[Kumaraswamy]

Please give me some time.

[TIMAI2]

@Kumaraswamy

if(append)

the file name should be : "compressed" + orginal name.

for example (append means add to end)

original file name: myImage1.png
optimised: myImage1-opt.png

That's not an issue. There is nothing to fix.

[Kumaraswamy]

@Anke

What does optimized mean? Original: left, opt: right

Sorry but the is the quality of output

@TIMAI2

for example (append means add to end)

Yes, but we can just add it in the output name?

[Anke]

@Kumaraswamy

is the quality of output

It's perfectly fine. I just wanted to know how the compression is done.
