  1. Hello: I am wondering if anyone has developed a VI to convert image data from the "Get Image" method to a PNG format string. I do not need compression or filtering and will only store RGB (24-bit), or paletted 8-bit (optionally, but not required). The trouble I am having is that the "write PNG file" and "LV Image to PNG" VI's are not supported in real-time. The BMP file writer works, but is not really a web format. I suppose I could write one, but I am under the gun on a project, and don't want to reinvent the wheel. Thanks.
  2. I'm getting the "Manager Call Not Supported" when attempting to save a PNG file on an NI Phar Lap ETS target. It's nice that the RTOS supports the "Get Image" method for control references, but being unable to save a PNG image makes that method pretty useless. The "write BMP file" VI works just fine, but who wants to generate HTML with BMP images? Is there a solution to the PNG vi, or has someone written an alternative? Thanks.
  3. Hi guys, I have to manage PNG images that don't come from a file, but from a TCP/IP connection. usually I use PNG data to LabVIEW image.vi to convert them into an image data cluster, but this time PNG images are different, I think. These images can be opened with all software without issues, anyway in LabVIEW PNG data to LabVIEW image.vi returns error code 1097. Unfortunately, saving received strings into temporary files is not possible in my app, so I need to convert them on the fly. have you ever seen this error? attached you find a sample code and an image sample. regards, Claudio image conversion.zip
