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, Ronie Salgado

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. Regards, Sven
Thanks, It works very well. Greetings, Ronie Salgado 2013/11/22 Sven Van Caekenberghe <sven@stfx.eu>

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. Stef On Nov 22, 2013, at 7:45 PM, Ronie Salgado <roniesalg@gmail.com> wrote:
