Serving pictures from the image
Locked
 
|
Hi
How would I go about serving a picture from within the image (not using static content) and making it a link? And then (not Seaside related), how can I read the picture into the image in the first place? Probably some basic stuff, but I'm new at this :) Thanks, JP _______________________________________________ Seaside mailing list [hidden email] http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside |

This is a really helpful tiny FAQ - I wish I had known about it earlier. Thanks Michel. Shouldn't this FAQ be advertised on the seaside web page (along with instructions on how to view it)? It clears out many of the problems beginners run into when starting Seaside and try to follow the tutorials found online. Nearly all the tutorials use the old WAHtmlRenderer which is not used by default in a new Seaside installation - this FAQ explains the difference and reasons behind the switch. Regarding the files, I am looking for a way to serve binary data from directly within the image itself, not using files on the external filesystem. I'm planning on using Magma as the persistent repository for everything and don't want to rely on stuff out on the filesystem, hence I need a way to load and serve my images completely from within squeak.

I'm trying to learn as much as I can about Seaside and I think tutorials are the best way to do that. Looking forward to it.

But how do I load the document from disk into aByteArray? I think I can do this using a web form, but I want to be able to load it directly from the filesystem (used in a batch load later).

Here was a method I used quite some time ago for a Seaside app that had to have the pictures in the image ;) Basically, I loaded the jpeg files from the hard drive and put them into a class side Dictionary. I had a singleton JPEGImages class through which I would reference the dictionary. When I wanted to transfer things between images, I would save the dictionary as a reference stream and could load that in with a different message on my JPEGImages class. Here is the import method from the JPEGimages class: importFromPath: pathString | jpegFiles thisDir | thisDir _ FileDirectory on: pathString. jpegFiles _ thisDir fileNamesMatching: '*jpg'. jpegFiles do: [:ea ||fileStream | fileStream _ thisDir readOnlyFileNamed: ea. DictionaryOfImages at: ea put: ((JPEGImage fromStream:fileStream) name: ea)] And the JPEGImage class: Object subclass: #JPEGImage instanceVariableNames: 'height width contents name' classVariableNames: '' poolDictionaries: '' category: 'AbleLink-Utility-Images'! asMIMEDocument ^ MIMEDocument contentType: 'image/jpeg' content: self contents! ! contents ^ contents! ! contents: aFileStream | tform | contents _ aFileStream contentsOfEntireFile. tform _ ImageReadWriter formFromStream: aFileStream binary. width _ tform width. height _ tform height. ^ self.! ! height ^ height! ! name ^ name! ! name: aString name _ aString! ! width ^ width! ! "-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- "!

I did the following. Firstly I initialized the gifs. I could do this because my gifs are fixed, I don´t need dynamic files: SomeClass>>intializeGifs |gifs imagekey newGif| gifs:= (FileDirectory on: 'C:\SES\product\squeak 3.8\working\img') fileNamesMatching: '*.gif'. gifs do: [:gif | imagekey:= ('DES-',(gif copyUpTo: $.)) asSymbol. newGif:= (FileStream readOnlyFileNamed: 'C:\SES\product\squeak 3.8\working\img\' , gif) reset; binary; contents. ScriptingSystem formDictionary at: imagekey put: (newGif)]. where 'C:\SES\product\squeak 3.8\working\img' is a path in the server context. Then to use them: MyWAHtmlRenderer>>getImage: anImageName withPath: aPath |imagekey newForm| imagekey:= ('DES-',(anImageName copyUpTo: $.)) asSymbol. (ScriptingSystem formAtKey: imagekey) isNil ifTrue: [newForm:= (FileStream readOnlyFileNamed: ((FileDirectory default pathName),'\', aPath,'\',anImageName)) reset; binary; contents. ScriptingSystem formDictionary at: imagekey put: (newForm). ]. ^self imageWithForm: (ScriptingSystem formAtKey: imagekey). and also override... MyWAHtmlRenderer>>imageWithForm: aForm self image: (self context urlForDocument: aForm) and defined: ByteArray>>asMIMEDocument ^MIMEDocument contentType: 'image/gif' content: self Bany, Michel wrote: _______________________________________________ Seaside mailing list [hidden email] http://lists.squeakfoundation.org/cgi-bin/mailman/listinfo/seaside |
