I’m attempting to use the “Image Placeholder” component in the Report Designer, and have some questions. Basically, what I am wanting to do is to use the Image placeholder to display a picture of a graph (an Equipment Schedule Component from the root container) in the Report Designer. The report designer has some good functions, but it can’t make what I want to display in the Equipment Schedule Component. I want to make some special plots using the Ignition components and include them in the Report, thereby extending the functionality of the Report Designer.
I can get an java.awt.image.BufferedImage object by:
but I can’t figure out how to convert this object to a Byte Array needed by the Image Placeholder. I want to eventually get to:
but I am missing the conversion code between it.
In the Report designer, I have a custom property “imagedata” as an empty dataset, which is set as the “key” of the Image Placeholder. If I write the byte array to that dataset, it should work to create an image of the equipment schedule.
So, how do I convert from the Buffered Image to a Byte Array that I can write to a dataset? I can’t find a method in the javax.imageio class to help, and there’s no BufferedImage.toByteArray() function available natively. Thanks.
