How images can be loaded

Hello,

I would like to know how I could load .png image into pharo, and being able to access to their pixel data for manipulation or display it.

Greetings,

Here is an example:

'/Users/Sven/Desktop/test.jpg' asFileReference readStreamDo: [ :in |
(JPEGReadWriter on: in) nextImage asMorph openInWindow ].

Inspect the results of #nextImage or #asMorph to learn more, this code actually opens the image in a window in Pharo.

Sven

hi ronie

to get access to pixel have a look at the Form class (you also have the BitBlt class).

Once you have a Morph you can get its form normally sending it form.
