SVG and smart images
by Alexander James Tucker 03 Nov '01

03 Nov '01

Hi, Has anyone got any pointers, or good ideas as to how to achieve the following? I'd like to be able to use SVG based images on my site, where possible, for a number of reasons -- one being that I'd like to be able to print out documentation and diagrams without jaggies. But I'd like my site to be viewable from different browsers and platforms without necessarily having to have SVG plugins installed everywhere. My thoughts are to create a smart image product, which wraps an SVG image document and delivers it unharmed only if the browser specifically says it can accept image/svg (or whatever the mimetype is). In all other cases, I'd like to be able to have PNG/JPEG content returned, either automagically generated and cached on the fly, or more likely in the first instance have a manually uploaded rendition returned. Does anyone know if this would be easy, whether it's already been done, or know of a simpler solution using client-side Java applets? Alex.

Zope BOF at Comdex in Vegas?
by Michael R. Bernstein 03 Nov '01

03 Nov '01

As the only (AFAICT) Zope user in Las Vegas, I'd like to propose that Zopistas that are here for Comdex (Nov 10th through 16th) get together for a Birds Of a Feather gathering. This could be a dinner or just meeting for drinks, depending on what people would like. How many people would be interested? Does anyone have a preferred time-frame? Here's hoping to meet some of you, Michael Bernstein.

RE: [Zope] using a method as the img name
by Jeffrey Robinson 03 Nov '01

Hi Trevor; I find the easiest way to do this is to use relative URLs on your Zope server, using <img src="images/header.gif"> instead of the absolute path. (This way you can reference it from almost anywhere in your site and let acquisition do the work for you).

RE: [Zope] Newbie Question

Hi Lynn, I have cc'ed the group as I'm sure there are other thoughts on this out there. First Question: Once you have your ZSQL methods working, create a Z Search Interface to see how to create forms and result methods automagically. Their just plain DTML methods. Using the form and results DTML methods that the Z Search Interface generates, look at how it is setup to create your own DTML method containing three forms, each pointing to a different ZSQL method. Second Question: I imagine you could do something like putting the ZSQL method name in your database, and using them to refine your search? So your main form would call a ZSQL method that returns you data, and the names of four other ZSQL methods, perhaps sql_1, sql_2, sql_3, sql_4. Use these fields to make a <a href> link on the results of the first ZSQL, so you can click result 4, for example, and it executes sql_4. Third Question: Are your labels stored in the database? If so, just call those columns as the name. If not, you may be able to do something like <dtml-if expr="result_1 == '1'>USE</dtml-if>. Python is probably a better tool here. -Scott -----Original Message----- From: Lynn Mayes [mailto:LMayes@advpol.com] Sent: Friday, November 02, 2001 3:04 PM To: 'Meilicke, Scott' Subject: RE: [Zope] Newbie Question Hi Meilicke, I gave it a shot - but I keep getting either key errors, or can't submit a string into an in tag. Anyway, specifically here - I have already created an outer join query from 2 tables - the query is actually a ZSQL Method select query. It works fine. I also have created 3 separate ZSQL Methods querying 3 different ZSQL Methods - they all work individually. What I want to do is have all 3 queries on an interface of somekind, so when they pull up the page, they click on whichever search they would like to do. Also, I would like to know how to put another ZSQL method into the query results page - do you know how? Like query A spits out data 1-4, and on the results page, I want to further look at item 4. Lastly, I have data on the SQL tables that came from an Access form option box, items 1-4. All that show up in the table is the numerical value. Within the ZSQL method, I would like change change the 1 to say "USE" . Do you know how this would work?
