Displaying an image from a file

Hi all,

How can i make a morph display an image from a file at my hd? How can i further "save" this image inside a class so to be ported via packages?

Thanks,

Laura

Just look at FileReference>>gtInspectorPngIn:

To see the effect, inspect the a .png file reference.

Cheers,

Doru

As for the saving, you can also look at http://smalltalkhub.com/#!/~peteruhnak/IconFactory (or just browse ThemeIcons, which is already present in the image), which stores the images in methods as base64 strings.

Here are two examples that contain elements of what you want:

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

(FileLocator workingDirectory filesMatching: '*.jpg') do: [ :each |
(each withExtension: 'png') writeStreamDo: [ :out |
each readStreamDo: [ :in |
(PNGReadWriter on: out) nextPutImage:
(JPEGReadWriter on: in) nextImage ] ] ]

Seaside has file library objects that store images and other resources as methods.

Re: Displaying an image from a file

Ok ! The snippet explained the reading from file, and ThemeIcons explained the saving-to/loading-from method.
