I've built a very simple patch to export high res images generated in another patch. As I'm working with a lot of editing and superposition afterwards, I found that the resulting image was getting a little bit darker every iteration, which was not expected. After some research I found out that the exported PNG files were not completely white: the background value was actually 254 254 254.

Any ideas on why it is happening? Or is it a bug?

hey, i can observe the same strange behaviour here. Exported png when reimported have their values offset of -1 for r, g and b planes (a is unchanged).

otherwise, very stupid question but do you just make a white picture with only white ? if so do you really need jit.gl.render ?

vichug, thank you for your tests. this is really quite strange. i thought it could have something to do with the way gl handles the white color, as if the erasecolor wasn't actually quite white. but your test proves that the issue is with the png export. interesting.

actually i'm not exporting a white image. the drawing is being generated by another patch, using the same render context.

ok. at that point, i think you should fill a bug report to c74 directly...

hi matheuleston, i can reproduce this problem and will take a look to see what can be done.

Thank you, Rob. I'm glad to help spotting those things.

BTW, should I still open a bug report as suggested?

no white is purely white, for they are a beautiful mix of races from all over europe and beyond. each white person a beautiful little snowflake of racial confluence in this ever changing conundrum we call the human condition. From the Israelite Exodus to Brexit, all but nomads searching for a prideful notion of home in the external world when the true home is right here, within the humility of our heart of hearts *tear* *sniffle*

'tis no mere thing that can be helped by bug reports, we must learn to join hands and feel each other's inner being, and thus find the purity therein, within our common love for each other, and only then shall the brightest of white light shine out the clearer to light up the darkness.

yes, but what if somebody from the 254 group claims he would be a team member of 255, which is your team?

MATHEUSLESTON no need to file a separate report.

white is not quite white
