PNG Question

[fuglyfreaker]

I have a question about that PNG format, as to why it was chosen to be the default

"save as" format.

I mean, I know you have to choose one to be the default when programming the

Save As thingy. And I know that jpg would be kinda late 1990s cheesy. And I'm sure

BMP would be too early 1990s and too large a save MB wise (though you can greatly

smallify the sizes by putting them in zip folders).

Also, I know (from reading yall posts about users trying to change the default save as

directory) that the yall believe that PNG is superiour to jpg as it is considered

"lossless"...so I guess that is the reason?

I dunno, I just don't like the look of that PNG as an extension. It just don't look

right. I got a bad feelin' about that one, etc.

 

Just wondering,

When you save an image with PNG and open it again later, it will be exactly the same. Every single pixel will have exactly the same color values it had before. This what is meant by lossless. The same is not true for JPG, which changes things to get a smaller file size.

And I'm sure

BMP would be too early 1990s and too large a save MB wise (though you can greatly

smallify the sizes by putting them in zip folders).

PNG is kind of like putting a BMP in a ZIP, but in such a way that you can open it again without opening the ZIP first.

Paint.NET defaults to the PNG format for single layered images because, as Pyrochild said, the format is lossless.

 

If your image has multiple layers then Paint.NET will default to the native *.PDN file format in order to save all the data again without loss.

 

These defaults are there to ensure that, by default, you do not lose any data.  Changing the file format is a conscious decision you make when saving a file - hence the loss of data is one you take responsibility for.

 

"Hey, I had a 132 layer JPG open in Paint.NET and I saved it!  Now when I open it there is only one layer....".   Yes.  That's because you chose to change the file format when saving.  Sorry, but the layer structure is shot.  Weep.
