    ImageGen and slimmage.js

    Hello,

    I'm not sure if I'm implementing this correctly with ImageGen 2.9.1

    Is this the right HMLT output to get slimmage to work its magic on top of ImageGen magic?

    <img src="~/ImageGen.ashx?image=XXX&amp;class=newsFull&amp;slimmage=true&amp;width=650" alt="xx" class="newsItem" />

    I don't need anything else apart from latest version of ImageGen 2.9.1 and slimmage.js, right?

    Should I see in the "cached" folder several sizes of the same image?

    Thank you!

    Hi Franz,

    Here is a episode http://uhangout.co.uk/video/_98Q0j2mE40 from uHangout where Douglas Robar explains how you can use ImageGen and Slimmage together. If you donĀ“t want to see the full episode, the explanation on ImageGen and Slimmage starts at  20 minutes into the episode.

    Hope this anwser your question.

    /Dennis

    Thanks Dennis, I think it does! I've implemented the same markup as Doug used on the uHangout and it seems to be working... :)

    Uhm, new question however about ImageGen and slimmage.js.

    We have the professional version and are using classes. It seems that even if slimmage.js does its tricks, the ImageGen class overrides the resizing, resulting in the same image (same Kb size) being downloaded by the client no matter what slimmage does (which is confirmed on the JS console)

     

    Slimming: updating /ImageGen.ashx?width=320&quality=90&image=/media/571195/nanana.jpg&class=newsFull
    slimmage.js (line 14)
    Slimmage: restored 1 images from noscript tags; sizing 1 images. 11ms
    slimmage.js (line 14)
    Slimming: updating /ImageGen.ashx?width=640&quality=90&image=/media/571195/nanana.jpg&class=newsFull
    slimmage.js (line 14) Slimmage: restored 0 images from noscript tags; sizing 1 images. 17ms slimmage.js (line 14) Slimming: updating /ImageGen.ashx?width=800&quality=90&image=/media/571195/nanana.jpg&class=newsFull
    slimmage.js (line 14) log: Slimmage: restored 0 images from noscript tags; sizing 1 images. 6ms

     

    See attached screenshot from Firebug.

     

    This is the "newsFull" class as defined in the ImageGen config:

      <Class Name="newsFull" OverridesQueryString="true">
        <AllowUpsizing>true</AllowUpsizing>
        <Width>650</Width>
        <Height>360</Height>
        <Crop>Resize</Crop> 
        <CachingTimeSpan>604800</CachingTimeSpan>
      </Class>

    Hum so I think the problem is that in the class we define a width for the cropping, and the OverridesQueryString="true" does what's expected: ovverrides the width coming from slimmage.

    So, I think it all boils down to: how can we use the crop feature of the professional edition with slimmage?
