Using many complex dynamos on a DeltaV Operate picture can burden the CPU and potentially slow screen redrawing. Complex dynamos typically contain more than 25 objects per dynamo.
To increase performance, complex dynamos can be converted into bitmaps directly, or you may choose to animate a portion of the dynamo first and then convert the remainder to a bitmap. Bitmaps will usually draw and load faster than groups of DeltaV Operate objects.
To convert a dynamo into a bitmap
One downside to a bitmap is that it is rectangular and that it may cover up the objects below it. DeltaV Operate has the ability to make bitmaps transparent, which allows underlying objects to show through.
To make a bitmap transparent
Right-click on a bitmap and select the Transparent Color menu.
Select the color that you want to make invisible. Usually this is the background color of the bitmap.
Right-click on the bitmap and select the Enable Transparency menu.
If parts of your bitmap are transparent that should not be
Before selecting Copy As Bitmap, change the picture (*.grf) background color to an odd color that is not in your dynamo. BrightMagenta might be a good choice.
Choose that same odd color (e.g. BrightMagenta) as your Transparent Color.
Animating a Complex Dynamo
Sometimes you need to animate a complex dynamo, but converting it to a bitmap would prevent you from animating it. In this situation, you may consider animating a portion of the dynamo and then converting the rest of the dynamo to a bitmap. You can then overlay the animated portion over the bitmap portion. This technique allows you to have animation, but with the performance boost of a bitmap.
Ungroup the complex dynamo.
Select the objects that you want to animate and move them off to the side.
Convert the remaining objects to a transparent bitmap.
Apply animation to the objects from step 2.
Group these animated objects, apply Bring to Front to the group, then slide the group on top of the transparent bitmap.
