The first thing to check is that the Professional features are enabled. For your site, visit the /imagegen.ashx?version page and be sure it says that ImageGen Professional is enabled for your domain. If it isn't, double-check that you have the proper entries in the web.config file and the domain registration key in the /config/imagegen.config file.

Once you've confirmed that you have ImageGen Professional activated then the classes in the imagegen.config file will be available (they only work when you have Professional). If you've made the entries in the "default" class then they will be applied automatically. If you've made your own class (such as one named "Mridul") you'll need to specifically tell ImageGen to use it for a request. For example, /imagegen.ashx?image=myimage.jpg&class=Mridul

Let me know how it goes.

ImageGen Basic version 2.5.7.27945
Professional features are available for localhost
Professional features are available for *.local

This is what the browser is showing when I visited the /imagegen.ashx?version page. Can you please show me how to add the domain of my website.

Also the following settings aren't working on the local development version. 

<Align>center</Align>

<VAlign>middle</VAlign>

But the constrain and altimage settings are working fine.

When you install ImageGen it should have added the correct entries to the web.config file and referencing the /config/imagegen.config file. The ImageGen Reference Manual PDF has instructions on how to update the web.config file manually though. 

<configuration>
    …
    <configSections>
        <!-- ImageGen Professional -->
        <section name="ImageGenConfiguration" type="ImageGen.ImageGenConfigurationHandler,ImageGen" />
    </configSections>

    <!-- ImageGen Professional -->
    <ImageGenConfiguration configSource="config\ImageGen.config" />
    …
</configuration>

 

As for the align and valign, do they work if you set them on the querystring and not in your class?

Note that when working on these kinds of issues it can be helpful to use the ?nocache=true parameter on the querystring to ensure ImageGen ignores any previously cached images and recreates the requested image to your specifications. Just don't use the nocache=true parameter in production because if you do you'll see your cpu and memory usage soar when every request is always regenerated afresh rather than using the cache.

The web.config is having the exact same settings that you have mentioned.

And setting the align and valign parameters inline in the querystring also doesn't work. And adding ?nocache=true in the querystring didn't help. 

What am I doing wrong?

It sounds like things are set up correctly.

Can you show us your ~/config/imagegen.config file's contents?

Any chance you could share a URL where I can see this happening myself? If you don't want to share it publicly on the forum, contact me through my website at http://www.percipientstudios.com/about/contact.aspx

Thanks for getting me access to your staging site.

When I visit the /imagegen.ashx?version page I see the following (domain obfuscated), which is correct and shows you have the web.config and imagegen.config files properly set up:

ImageGen Professional version 2.5.7.27945
Professional features are available for localhost
Professional features are available for *.local
Professional features are available for yourdomain.com

 

I also see the Align and VAlign settings working properly. For instance, this request puts the text in the middle of the image. It's in the middle because the 'default' class in your imagegen.config sets it that way.

/ImageGen.ashx?text=hi&width=400&height=400

 

I can't verify that changing the Align and Valign settings works because the default class has the OverridesQueryString="true" setting. Which means even if I set &align=right&valign=bottom on the querystring command they will be ignored because the settings for align and valign in the class will override those on the querystring. But I've confirmed the settings work properly on a local installation.

cheers,
doug. 

 

Thanks for checking the website. I thought that setting the Align and Valign parameters would place the image according to the container div. By reading your comment i understand that these parameters are used to align the text only.

Sorry that i've misunderstood this. But is there any way to aling the image as a whole instead of the text. 

Thanks a lot. It worked.

Can you also please tell me how to enable cache for the images? Now it takes almost 2 sec for each image to get loaded. So the loading time for a page is very high.

 

 

Server-side caching is always enabled so ImageGen won't have to make the same image twice, saving server resources. With ImageGen Professional you can also enable client-side caching on a per-class basis with the <CachingTimeSpan> in the imagegen.config file. All explained in detail the ImageGen Reference Manual pdf if you need more info.
