Thanks for the quick solution; well, the half solution because now, if I try to save it as a PNG, the program just forget my choice and saves it as a bkd !
Hum yes it's a little bug, anyway it's better to keep a BKD working file and consider PNG as an export when you’re finished...
And something I noticed, since the first time I used BI, the saved files loose some intensity on the blacks when reopened; I say in the blacks because for the moment I only used BI for pen drawings, in black and not for full color illustration, so I can not say if it also happens in other situations, But a saved black and white drawing sure fades when saved, PNG or BKD.
..because as you stated here BlackInk work in Linear color space ( unlike Photoshop and the majority of drawing softwares who work in gamma color space
) and then to be reliable BlackInk convert the result into Gamma color space for compatibility when you save in PNG. It's an operation which can alter some colors. That's why working with BKD is a better choise.
Anyway the fades you describe seems strange to me when you says it's fading do you refer to the image opened in Photoshop/other program or an image opened in black ink ( v0.115.1500 ) ?
This was a known issue before the version 0.114 and perhaps you try to open old drawings with a new version.
Do you still have this problem when creating drawings with the latest version ?
And thanks for your valuable support
