Writing characters to text file to convert the data into image

[MikeS81]

Hi Hasan,

is the data from your post before the entire image? Is it all you have? Can you upload a vi with your data in a string constant? What is the expected image format? Looks like jpg for me.

I need to write all the data into text file. The value 0x00 is interpreted as 0x20 in labview. how can I handle this?

Hi Hasan,

as already mentioned, write your file as binary file.

Can you upload such an example?

The problem i think is that .... while writing data to the file, labview converts 0x00 to 0x20 ...... how can i handle this?

hi mike... this is not the whole data, its only the frst package. I have 12 packets similar like this.

am attaching the file that i need to write them in text file as characters and then convert the extension of that txt file into jpg. so that i can read the image.

i have attached the whole file. I need to display this file as jpeg image. the image should look like the attached image (image.jpg)

the source code is very cumbersome to obtain all the data one by one following the protocols.

 can you please tell me how to convert the file (example values.txt) into jpeg image  using labview?... the image should look like the second attachment (image.jpg) in the previous post

Hi Hasan,

How are you converting/writing this hex file into jpeg image? can you please post your code?

what i am getting the image is attached here (Distorted image.jpg)

only first row is visible but the rest of the image is distorted. Please tell me how can I obtain the actual image?

Hi Hasan,

if you have the image data as text, as you have posted before, then the attached code works to generate the jpg file.
