MS Office Forum / General MS InfoPath Questions / August 2005PNG transparency in InfoPath
As you can modify the HTML output by an InfoPath view's .xsl template, I thought I might be able to use the AlphaImageLoader filter to display png images with transparency (as they don't render properly by simply inserting the png image). After thinking about it, it makes sense that this filter can't be used probably due to security restrictions around using the filter located in an untrusted domain. Is there any way to get image transparencies working in InfoPath (please don't say install IE 7.0 beta :) )? Perhaps I could use managed code to manipulate the image?? Thanks in advance for the help. It's probably placing the unfiltered image on top of the filtered one. Try using a transparent gif as the source for the IMG element and your png for the source in the call to the filter. You can also try applying the image and invoking the filter via css: http://koivi.com/ie-png-transparency/ > As you can modify the HTML output by an InfoPath view's .xsl template, I > thought I might be able to use the AlphaImageLoader filter to display png [quoted text clipped - 11 lines] > > Thanks in advance for the help. Thanks. I probably should have specified the implementation that I was using: I inserted a 1 x 1 pixel, transparent .gif into the InfoPath form so it would be included into the package (.xsn). I also inserted the .png file. I then modified the default view.xsl file to reference the images like so: <img style="FILTER: progid:DXImageTransform.Microsoft.AlphaImageLoader(src='BD55AF9E.png', scalingMethod='image'); WIDTH: 60px; HEIGHT: 48px" src="B55DBEE5.gif"/> All I get is a 60px by 48px blank image (obviously, the transparent .gif). I tried changing the size of the blank.gif to 10px by 10px and put a solid 1px black border on the image. If the filter was working properly, I should see a small 10x10 square with a black outline and the png image behind it. I put the above code (with the 10px size change) into a testpng.html file in the InfoPath project's working directory and opened in IE. Now, I got an "Active Content" warning and had to stop the content block. When I unblocked the content, I saw what was expected, a 10x10 square with the png image behind it. I'm thinking this is exactly why it isn't working in InfoPath...security boundaries. Now, the question is, can I circumvent this using managed code? > It's probably placing the unfiltered image on top of the filtered one.

It is my experience that filters/image transofrms do not work in InfoPath.  SignatureGreg Collins [InfoPath MVP] Please visit: http://www.InfoPathDev.com Thanks.

It sure would be nice if Microsoft took the png rendering from IE 7 and put it into InfoPath! HINT HINT HINT! For now, I just created a jpg with the background color set to the same as the header where I was placing it and created another with a white background for the print view. It's a hack, but works... > It is my experience that filters/image transofrms do not work in InfoPath. > [quoted text clipped - 52 lines] > > > > > > Thanks in advance for the help. I guess I didn't have my MSDN subscriber alias set up (which would explain why I received no responses on this issue from support). Now that I have set this up, I assume that I will receive a response within 2 business days. Is this the case? > Yes, I've come to that realization as well.
