I have one example for creating Pdf417 barcode using ActiveX technology EaseBarCd.dll. It all works fine, but the application creates an image of a different size depending on the resolution of the monitor and the type of graphics card. Does anyone know if there is a possibility in EaseBarCd to create an image that is always the same size regardless of monitor resolution and type of graphics card?

Given that you are probably "riding on default values" which are gleaned from the computer's display capability by default...

I'd bet what you are looking for is here:

First David, thanks for your reply. Even before my first question, I was working with the following properties that affect image size: ControlWidth, ControlHeigth, RasterImageResoution, BarTopMargin, BarLeftMargin, PDFModuleHeight, PDFModuleWidth and Autosize. That seemed to me to be enough then, and it seems to me now after additional consideration of those properties and all other properties of EaseBarCd. No matter how much I considered them, I could not figure out where I could even look for a solution, let alone find a solution.
There is nothing in the existing manual that would point me to a solution.
Another issue that I didn't mention earlier is the image display in ReportPro. In fact, this is the question that caused the first question and the need to have the image always the same size. I inserted the image in the report and adjusted the size. ReportPro stretches or shrinks the image created in EaseBarCd according to its algorithm. The problem is that the image is stretched unexpectedly in different resolutions and graphics cards. For example I tested the image at the same resolution 1920x1050 on two different computers and I get two different sizes on the printout !? On one computer it works fine on all resolutions, but on the other it doesn't. When I set the ratio and layout (text size in applications) to, for example, 1.25%, then I get a printout in sizes that satisfy me. Of course, this is not very convenient because clients would have to choose that option on their computer regardless of what they want. I tried to create a barcode in the Zint program, which creates an image of the same size on different resolutions and graphics cards without white spaces, but Zint also creates an image of a different size at a text size of 125%.

Which may be this problem also, ReportPro down-scaling the actual good output? Better start a new thread, not sure this title will draw any attention of someone that can help now..

EaseBarCd creates an image of different size depending on the resolution and creates an image in which the barcode is only part of the overall image. Zint creates a barcode image of the same size regardless of resolution, an image of the barcode as it should be, without gaps. ReportPro correctly displays such an image from Zint when the correct image sizes are set in ReportPro.

You are right !
Thanks
