Thanks, I have displayed the images which them was stored in a Oracle's BLOB field, with:
<dtml-call expr="RESPONSE.setHeader('content-type','image/jpeg')"> <dtml-in SQLMethod_with_a_Only_Row> <dtml-var expr="BLOB_FIELD.read()"> </dtml-in>
However, I would like to resize this image. I can not do it with the "height" and "width" attributes, because the image is >obtained from a Oracle's BLOB field, and no from image object (i.e.: I can not use <dtml-var "ImageObject.tag(border='5', >align='left')">).
How can I do it ?
I don't understand why this would make any difference. The code above is to send the actual image data, the resizing is done when you create the IMG-tag, which I assume you create somewhere else. Or don't you have an IMG-tag at all, just a link? If you actually want to resize the image itself to send less image-data, the PIL library can be used to do that. But it seems easier to resize the image before putting it into the database in that case.
