[Seaside] serve jpg image files from form objects

Oh I see, sorry, this would prompt the user to download a file, not quite
what you had in mind.

Cheers!

hey boris,
thanks for your answer and code example. 
i am not clearly about if you just provide a link to the file or if you get
it rendered to the website.
especially the message : 'self pngImageByte' ! does it return a ByteArray?


	WADocumentHandler 
	document: self pngImageBytes
	mimeType: 'image/png'
	fileName: 'image.png') response


because thats what i thought the message : 'aForm bits asByteArray' is doing
:


		html imageWithDocument: aForm bits asByteArray
		                mimeType: 'image/jpeg'
		                fileName: root name,'Picture', '.jpg'.


does anyone know how these methods are meant to be used? or is there some
strange conversion problem from Form -> bits -> asByteArray?

best

martin

i want the jpeg file (hold in a instance variable of type form) to be
RENDERED. not only a link to the data.

	Here's what I did to serve PNG files from VisualWorks,

	(html anchor)
	 attributeAt: 'rel' put: 'lightbox';
	 callback: [self session 
	returnResponse: (WADocumentHandler 
	document: self pngImageBytes
	mimeType: 'image/png'
	fileName: 'image.png') response];
	with: [(html image)
	style: 'border: none; padding: 0px;';
	url: (self pictures addToPath: 'view.png');
	altText: 'View']

	Hope this helps,

	hello out there,
	allthough i browsed throught the archives i couldn`t find the answer

	to my problem.

	i want to serve a jpg-file which is stored in a Form object.
	so i do : aForm _ (Form fromFileNamed: 'wave.jpg')

	then i tried the following inside the #renderContentOn:  method :

	
	

	html imageWithDocument: aForm bits asByteArray
	mimeType: 'image/jpeg'
	fileName: root name,'Picture', '.jpg'.

	this doesn`t work, and when i am acceptin the following, seaside  
	seems to convert the jpg file to gif or wracks up the picture file  
	somehow :

	html imageWithDocument: aForm
	mimeType: 'image/jpeg'
	fileName: root name,'Picture', '.jpg'.

	anybodys having some experience with this issue?
	thanks for help!

	martin
