Paint.NET 3.5.4 cannot open this png correctly

[bpmtri]

Dear Paint.NET team,

I open a PNG file in Paint.NET 3.5.4, but it is displayed incorrect. Please try the file I attached.

Thanks.

It loads just fine here. Please describe precisely what you mean by "displayed incorrect." And which version of Windows are you using.

This reproduces on my Vista PC - PdNv3.5.4.

Same with MS Paint.

Works OK with Gimp and Irfanview.

And if opened and saved in either of these programs,

without any editing, will then display OK in Paint.NET.

Also, if you copy the image from online,

then paste it into Paint.NET it will display

correctly and when saved can be re-opened

with correct display.

My Windows version is Windows XP Service Pack 3. Please the the screenshot in the attachment.

Thanks

My guess is that this is due to the underlying GDI+ codec.

In Windows 7, the GDI+ codecs were actually rewritten to use the WIC codecs (Windows Imaging Component), which is known to be superior in many quality-related reasons ("quality" referring to software and engineering quality, and in this case the image quality is only a corollary).

This will not be fixed in the Paint.NET v3.5.x timeframe. I'm planning to redo all the Paint.NET codecs to use WIC directly for Paint.NET v4.0. For now, use the workarounds detailed above.
