Doru, I think you will need the new #binaryReadStream or #binaryReadStreamDo: Sven On 02 Feb 2014, at 20:15, Tudor Girba <tudor(a)tudorgirba.com> wrote: > Hi, > > I have troubles creating a PNG file in memory. > > I can create a PNG file on disk and load it back without problems: > f := FileSystem disk workingDirectory / 'pharoicon.png'. > f writeStreamDo: [ :stream | > PNGReadWriter > putForm: ThemeIcons current pharoIcon > onStream: stream ]. > f readStreamDo: [ :stream | PNGReadWriter formFromStream: stream binary ] > > But, when I try the same thing in memory, I get an exception for incorrect format: > f := FileSystem memory workingDirectory / 'pharoicon.png'. > f writeStreamDo: [ :stream | > PNGReadWriter > putForm: ThemeIcons current pharoIcon > onStream: stream ]. > f readStreamDo: [ :stream | PNGReadWriter formFromStream: stream binary ] > > Can anyone point me to what am I doing wrong? > > Doru > > > -- > www.tudorgirba.com > > "Every thing has its own flow"

creating a png filereference in memory

by Tudor Girba

Hi, I have troubles creating a PNG file in memory. I can create a PNG file on disk and load it back without problems: f := FileSystem disk workingDirectory / 'pharoicon.png'. f writeStreamDo: [ :stream | PNGReadWriter putForm: ThemeIcons current pharoIcon onStream: stream ]. f readStreamDo: [ :stream | PNGReadWriter formFromStream: stream binary ] But, when I try the same thing in memory, I get an exception for incorrect format: f := FileSystem memory workingDirectory / 'pharoicon.png'. f writeStreamDo: [ :stream | PNGReadWriter putForm: ThemeIcons current pharoIcon onStream: stream ]. f readStreamDo: [ :stream | PNGReadWriter formFromStream: stream binary ] Can anyone point me to what am I doing wrong?

Then I guess the simplest way to go, would be to add some ogg files with pre recorded sentences. In this way the child could have the letters and the sound at the same time and begin to learn to read while doing some maths...

Hi Hilaire, The instructions are written in small characters, which supposes that the child who tries the exercises is rather old; yet before a child is able to read complete sentences like this, he/she learns the numbers. So I wonder if your application would not benefit from voice synthesis. Which yields me to an other question: Is there already voice synthesis in Pharo? If yes, how many languages are implemented?
