Re: [Pharo-users] creating a png filereference in memory

by Tudor Girba

I see. However, I still do not understand two things: 1. Why does it work if I read and write to the file system? f := FileSystem disk workingDirectory / 'pharoicon.png'. f writeStreamDo: [ :stream | PNGReadWriter putForm: ThemeIcons current pharoIcon onStream: stream ]. f readStreamDo: [ :stream | PNGReadWriter formFromStream: stream binary ] 2. Why is binaryReadStreamDo: not equivalent to: f := FileSystem memory workingDirectory / 'pharoicon.png'. f writeStreamDo: [ :stream | PNGReadWriter putForm: ThemeIcons current pharoIcon onStream: stream ]. f *readStreamDo:* [ :stream | PNGReadWriter formFromStream: stream *binary*] Cheers, Doru On Sun, Feb 2, 2014 at 11:23 PM, Sven Van Caekenberghe <sven(a)stfx.eu> wrote: > > On 02 Feb 2014, at 22:13, Tudor Girba <tudor(a)tudorgirba.com> wrote: > > > Thanks!

Hi Hillaire I pulled the code from smalltalhub and the resources, into pharo3. The LEDMorph dependency was resolved by pulling it from PharoExtras. I couldnât find a starting point for demo so I tried the following in a workspace: Stoa beUnix. StoaApp current show. But not having much luck. Do you have any workspace scripts you use to test your app?

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...
