Creating versions of an image
The following example shows how to create an application that lets you generate four versions of the same image,
display the versions in a form, and choose which one to save. The application comprises three ColdFusion pages that
perform the following tasks:
• Dynamically populate a drop-down list box from a database query.
• Use the
tag to create a ColdFusion image from the title selected from the list. Use the
cfimage
to create three clones of the ColdFusion image. Use the
each clone.
• Save the file chosen from the form to a new location.
Example
On the first form page, create a query that selects the artwork from the
in a pop-up menu:
<!--- Create a query to extract artwork from the cfartgallery database. --->
<cfquery name="artwork" datasource="cfartgallery">
SELECT ARTID, ARTNAME, LARGEIMAGE
FROM ART
ORDER BY ARTNAME
</cfquery>
<!--- Create a form that lists the artwork titles generated by the query. Set the value to
LARGEIMAGE so that the image file is passed to the action page. --->
<cfform action="dupImage2.cfm" method="post">
<p>Please choose a title:</p>
<cfselect name="art" query="artwork" display="ARTNAME" value="LARGEIMAGE" required="yes"
multiple="no" size="8">
</cfselect>
<br/><cfinput type="submit" name="submit" value="OK">
</cfform>
On the first action page, clone the original image three times, change the sharpness setting for each clone, and display
the results:
