[8-bit Image Save as a new file without any editing, the Data are all changed]

Hi MJW,

Thank you for your advice.

I'll check if it's the color issue in my code.

Thank you very much.

[8-bit Image Save as a new file without any editing, the Data are all changed]

Hello MJW,

 

Although the two images seem to be the same ,data of these two are not the same when I print out the log at the same location of the buffer like : data[100], data[1000], data[1500]...etc.

It does confuse me at this part...

It's all before the function to show the segmeation images on the tool.

But I will chek my code.

Thank you very much.

Hello MJW,

 

Sorry for the unclear description.

 

I mean the preview icon of these two images look the same.

But when use my own tool(MFC tool) to load the bitmap data into a buffer and then show on my picture control item.

It looks more darker than loading the original one.

Again, I apology for the unclear description...

Thank you very much.

Hello,

I uesd the paint.net to load an 8-bit image (called it A).

And save it as a new 8-bit image file (called it B).

The look of these two are seem the same.

But after I read the hex data of them, their data are not the same.

For example, the offsetvalue (10th byte) of A is 1078, but 474 for B.

And after reading all the bitmap data and show them on my own tool.

The B's picture is more darker than the A one.

Can anyone tell me why there's a difference after saving image without any editing?

Thank you very much.
