How do you create a 0x0 Pixel image?

Hi people,

Possibly a very noob question but I am just wondering how this can be done? I need it for a test and I have used Irfan view to edit an image but it is not working very well.

Its late in the day so dont all laugh at me

Cheers

AFAIK you can't. Closest would be a 1x1 transparent gif/png.

Why do you need this?

Hmm, the only way I can evenly remotely presume to fool a program into thinking you have a 0x0 image is to create an empty text file and change the extension to .jpg?

Nothing will open it properly though.. there is nothing to display..

You using it for tracking?

You could create it with a hex editor, pick a simple file format like BMP and find the format specification and just define the bytes one by one.

Thanks guys, need the image to replicate an issue the customer is getting I know the problem is basically an image with nothing but there is actually a display image (its a cartoon image) so a little confused so wanted to try in testing environment.

Afaik all you have to do is write a header with image dimension sizes zeroed.

If you want to do it programatically just malloc the 54 byte header, assign the values and write to file
