  1. OK, summing UP, I found three different solution: 1) Using AcroPDF Activex Object 2) Using Ghostscript 3) Using Sumatra PDF And that's all. Thank you
  2. As I already told to others, I don't nett to print TO PDF but print A PDF, so an already existing PDF document has to be printed on paper (label in my specific case).
  3. I use 2017 so i can't open VI in 2018. But as i can imagine from the VI name, you are printing TO PDF, I need to print A PDF instead, send a PDF file to a printer.
  4. Yes, I've posted my question to both forums 'cause I expect different users use different forums so better possibility to have suggestions.
  5. Hi, I'd like to print a PDF File. No need to manipulate it, only print. I found some suggestion about using command line via System Exec VI like this: "<Path to AcroRd32.exe>" /t "<Path to document>" "Printer name" But it doesn't seems to work. It opens acrobat reader but it doesn't print. Any solution can be accepted, even using firefox or chrome or whatever else. thank you!
  6. Hi, is it possible to create and resize a button in a running vi's front panel? I would like for example to place a square button where I press mouse down and then, if I drag left and right borders, resize it. I've done something similar in the past using images, but this time I need buttons to be single objects I can move in a second time
  7. At the moment I solved using IMAQFillImage VI. That VI allow, using a binary image as mask to determine which pixels has to be overwritten, to do what I need. Beeing an 8bit grayscale image it allows me only to choose 255 gradients from black to white, but converting the image in a coloured one, it allow to use every color I want.
  8. It's really not clear to me what you said.... At the moment I've used Image To Image vi using the thresholded image as Small Image and as mask as well. It works but it doesn't allow me to choose the color of the overlay. It's always black.
  9. Hi, I would like to threshold a binaty image showing to the user the original Image overlayed by the thershold result like the Vision Assistand does. I've tried with the Keep/Replace Value input in the threshold VI but it does the exact opposite of what I need (it replace or not the thresholded image leaving BLACK the rest) I need to replace the thresholded values with a user color and leave the rest of image as it is. Any suggestion on How to do it? thank you so much.
  10. My fault It was not a strange Offset, it was a specific offest I was setting before using the mask and that I did not disconnect from the offset terminal Now all work fine Thank you!
  11. This is s what I'm trying to do using the Image Mask input of ImagetoImage VI but If I do so, as you can see in attached file, in the result, the inside part of the image has a strange offset... unisci immagini FINALE.vi
  12. Hi, I have an application where I need to extract a portion of an Image, binarize with different threshold the two part of the original image and then merge them back. To do so, at the moment, I trace a rectangle on the original Image, use two Mask from ROI VI to extract the inside and outside portions of the image and then I use the IMAQ ImagetoImage 2 VI to merge the two parts. This procedure works only with rectangular ROI, But I need to do the same with a define by user Polygon. Any suggestion on How to do it? In the attached example If you rotate the rectangle you can see my
  13. My initial problem was on HOW to store blob data in an SQLite record field using this toolkit. So i thought this was the right place to make my question. I Had no idea about the problem of no standard for storing images on a BLOB field. Now that I know that, i can say: 1)Attached are 2 solution working with SQLite Manager but not with SQLite administrator neither with DB Browser for SQLite 2) Being so, maybe it's better to store images in a specific folder and store the path in the DB. Thank you so much for the support.
  14. As you suggested, I've made an example using Vision Library, starting from a previously stored image but nothing change. Or better, I don't get any error executing the VI and in the DB I can see the new record but using SQLite Administrator I'm not able to see the picture inside the DB. SQLite Administrator has a specific function that should show the image. I attach even the DB with 4 records with that should have the same image on it but I can't see it. DB_CN35.sdb
  15. As I told in my previous message, Because I Don't Know How to save my image as a blob in labview! The image is not originally stored in my PC but is acquired with Vision Libraries. So once acquired, Hwo to save it as a blob? And then How to pass it to SQLite library to store it into my DB?
