Vision- Image size

[Nainesh]

An image is created in photoshop or corel Draw and the size is A4 but when I open it in Labview Vision and Save it. It is not maintaining image size it is always greater than original size. A problem is occurred when I got print A4 size.
Also how could we control DPI (Dot per Inch) property of Image.
Recently I have developed one project in Labview Vision and upload Demo on YouTube

Icard Generator

So any body guide me to resolve it.

Let me know if any other information needed.

This is a bit complicated, since every image file type (jpg, tiff, ...) saves the dpi in a different way.

Then we have different representations of the image. In Corel it's vector based (as far as i know) and with NI Vision we have the "image" datatype.

So when opening an image in LabVIEW the dpi information might be lost.

At the other hand there is an example here which demonstrates how to set the dpi for jpg files.

Why don't you try to create images in other imgae creation program, and to be honest, im not familiar with PS or corel Draw for theis complex operation, but they are powerful. my opinion is that your creat your images in other way and open it in Labview Vision and Save it. you can have a try to see whether the prolem is sloved or not.
