Error when saving a big file

[ViliamF]

I am trying to save a 59049*59049 px image, but it gives me this error:

Application version: paint.net 4.2.13

It should not have problems with anything, meaning it should have enough RAM (64 GB), and anything it would need, as I have succesfully saved the same file on the same computer in  some previous version of the program.

Not all file types can handle all sizes of images, mind you. Sometimes due to the format, sometimes due to inadequacies or bugs in the underlying system codec.

 

However, In this particular case, it looks like WIC* is having trouble generating an 8-bit palette (or maybe 4-bit). This is part of the "Bit depth: Auto-detect" functionality in Paint.NET.

 

The good news is that I was able to reproduce this, and the even better news is that I was able to save the image just fine by manually choosing 32-bit for the Bit Depth (24-bit is also a good choice if your image has no transparency/alpha).

 

I may be able to fix this for the next update (4.2.14) so Paint.NET will automatically forget about trying to use 8-bit if it bumps into this error from WIC.

 

 

* WIC = Windows Imaging Component. It's part of Windows.

So for now you can't save any indexed format (8-bit, 4-bit, 2-bit, 1-bit) that's "too large". Seems to be around 26,500 x 26,500 pixels is the cut-off.

 

I'm trying to find a way to make those work, too. You should see the fix in the upcoming 4.2.14 alpha.

I was trying to save it with 1-bit setting, as it decreases the file size. Image is simply a black-and-white Sierpinski carpet.

 

I would be very grateful if you'd managed to make it work for 1-bit depth.

 

Also, I would like to ask, why can't I copy a file of that size into the RAM? (I have noticed this in past versions) It is about 3,5 billion pixels, and if every pixel was represented by a byte, it would be only about 3,5 GB of RAM.

 

Is it because pixels are represented by much more than a byte, or?

Each pixel in Paint.NET uses 4 bytes.

Once I make it work for 8-bit, then 4, 2, and 1-bit are no problem.

Thank you for the fix. I have one more "feature request" for you: It would be very helpful if I could set the color depth when opening new picture, so that instead of 4 bytes per pixel, I can directly use 1-bit depth.
