Hi,
I am using an external method to load an Image from the harddrive. The external method is as follows:
from email.MIMEImage import MIMEImage ##parameters=filename def getDocument(filename): fname = '/mnt/'+filename; input = open(fname,'r') content = MIMEImage( input.read( ) ) input.close( ) return content
When I try to display the content in the webpage what I actually got is
all raw data of the file rather the image. So how can I convert the raw data to be dispalyed as image in the
webpage. I am using ZPT to display the web page (image). If its dtml I
could have used <dtml-mime> tag is there any equivalent to that in ZPT.
Any suggestion would be a gr8 help.
It is not clear exactly how you are using the Page Template. Typically the page would have an img tag that calls a python script that calls the External Method. Remember the web browser fetches the image separately after the html has been received - so your img tag might look like this:
<img src="getImage?filename=whatever" ...> and your getImage python script would look like this:
(type, encoding) = context.getMimeType(context.REQUEST.filename)
context.REQUEST.RESPONSE.setHeader('Content-Type', type)
context.REQUEST.RESPONSE.setHeader('Content-Disposition', 'inline;
return context.getDocumentCall(context.REQUEST.filename)where getDocumentCall is the name of your External Method that calls the getDocument External Method and getMimeType is another External Method that looks like this:
import mimetypes
def getMimeType(filename):
return mimetypes.guess_type(filename)and your own external method would look like this:
> ##parameters=filename > def getDocument(filename): > fname = '/mnt/'+filename; > input = open(fname,'r') > content = input.read( ) > input.close( ) > return content
At the moment you seem to have skipped a step.
