All about Bitmap Images

the 12% at the top right corner gave me instant anxiety

[@bobatrix6704]

the reason white is 1 and black is 0 is because pixels are normally lights, so when white is displayed the light is lit, but is not lit when the colour black is displayed

This is gold for me, am trying to make a video player for an oled display who's resolution is just 128x64 pixels.

Thank you for the feedback, most appreciated.

So Zeb and the Wizard set to work and took off the wheels and the top, and then they put the buggy edgewise, so it would take up the smallest space.

thank you, that was helpful ♥

[@CSTeacher]

You're so welcome!

I couldn't figure out why 0 for black and 1 for white ...please explain

[@CSTeacher]

It is because black is the absence of colour, hence 0.

[@RabStalianY2K]

My answer to the question: White in RGB is (255, 255, 255) and Black is (0, 0, 0) if we take the average we get 1 for white and 0 for black

[@MaesterSilva]

Just one question. The positions: Is 0,0 at top or bottom?

[@noxtol8778]

At the left top corner

[@Worldwide_Productions]

In math it's on the bottom left, but most of the time in computers it's the top left.

Thank you That was very straightforward and clear. I wanted to ask why 3 bits is not 9, but 4 bits is 16. All number but 3 are raised to the power of 2. Is that correct?

[@maximilianhonig2049]

Indexing starts from zero i.e. for 4 bits: 1*2^0 + 1*2^1 + 1*2*2 + 1*2^3 = 15 In binary: 1111 We take 2 to the power of the digit we’re talking about (starting from zero). The 1’s represent 4 “1” boys if you will.

[@CSTeacher]

Thank you for the feedback. The reason why 3 bits is not 9 is that it is not 3^2 but 2^3, so not 9 but 8.

Also how may I create a file from scratch? (C++)
