Hi,

In versions 19.1.7 and 19.2.3 we fixed an issue that occurs in the SkinImageColorizer.CalcLightness method in the scope of the System.ArgumentException is thrown in the SkinImageColorizer.CalcLightness method report. To check if the current shortcoming relates to that issue, upgrade your app to the latest minor update 19.2.5 or 19.1.8.

If you are already using the latest version, would you please isolate the issue into a simpler compilable project and send it to us for further investigation?

Hello,
I upgraded to 19.2
problem still there. I would say it is even worse since I had it immeditalely after upgrade.
I cannot reproduce it. It happens randomly.
That is very ambarassing since the application jus crash with no hope to recover.
I beleive you should address that as a matter of urgency.
I don't see myself delivering an app where I know it can blow up any time.

Private DevExpress Support Team Private DevExpress Support Team 5 years ago

Hi,

I understand the urgency of this matter. We have analyzed our code and found several points to improve. Unfortunately, we cannot guarantee that these changes will fix the original issue since we cannot reproduce it on our side. That is why, we would ask you to request a hotfix and install it once it is ready. Usually, we provide hotfixes within a week. If you need it faster, just let us know.

We will update this thread once we introduce the required changes. Please bear with us.

Hello is that normal that the downloaded installer is named DevExpressNETComponentsSetup-19.2.5.20020.exe
Once installed, how can we be sure that the project uses the hotfixed libs ? (we still see reference to 19.2.5.0)
thx

Private DevExpress Support Team Private DevExpress Support Team 5 years ago

Hi,

We apply a hotfix to the latest available minor version, i.e. to version 19.2.5. Please refer to the How to request a hotfix KB where we describe this point.

To ensure that your app uses hotfix libraries, run it in VS and open the Debug -> Windows -> Modules window. Find our assemblies there and see what values the Version field has. It should show a nonzero value after the last dot.

There is a small typo above: the hotfix is for version 19.2.5 but juste before the link "Download hotfix", it is written 19.2.6

Private DevExpress Support Team Private DevExpress Support Team 5 years ago

Hi,

It is not a typo. We mean the version in which the issue will be officially fixed. That is why, you can see "Fixed In 19.2.6 / Next Release" there. Until the official minor update 19.2.6 is released, we provide a hotfix. A hotfix is generated by using our current intermediate build whose version is still 19.2.5.
