Image Downloading

Pharo Smalltalk Users mailing list
Hi.

I want to download images from Internet and save them on my local disk.
I will take the path of this image and put it in variable in pharo.

I don't  know how to proceed.

Thanks

Hi,

Here is a first idea of how to do it :

image := (ZnEasy get: 'http://www.w3schools.com/css/paris.jpg') contents.
file := 'file.jpg' asFileReference.
[stream := file  writeStream.
stream nextPutAll: image.
]ensure: [stream close].
ImageReadWriter  formFromStream: file readStream.


Cheers,
Vincent Blondeau

You can open images directly inside Pharo:

(ZnEasy getPng: 'http://pharo.org/files/pharo.png') asMorph openInWindow.

If you want, you can download to the filesystem as well:

(ZnClient new url: 'http://pharo.org/files/pharo.png') downloadTo: '/tmp/'.

The above uses the following as file name:

'http://pharo.org/files/pharo.png' asZnUrl file.

HTH,

Sven

Thanks all for your answers.

But now I want to access to some images on my disk from a rest client.

I have the name of the image in a variable.

Cheers
