I have 1 bit per pixel information and i have the width and height of
this data.Each bit corresponds to a 24 bit colour value. I want to
convert this to 24bit per pixel bitmap.
Do i need to multiply the width and the height by 24 or just the width?.
I tried to multiply the width by 24 but the value is too large?.....what
can i do?.
The 1bpp data is at resolution 600dpi.....can i just use the set
resolution function to change it to 96dpi...

I have trouble displaying a bitmap. I have 1bpp information. I also have
a command telling me what color i need to set the bytes to when the
colour is switched on. The trouble is i do all this but it will not
display properly. I convert this to 8bpp information. I set the relevant
pixel to for example "255,0,0" for Red.....is this right?....i set the
Red byte to 255 and the other two values set to 0. I think the Bitmap
data class i am...

Hi.
I use System.Drawing.Bitmap to copy bitmap pixel data.
I use LockBits to retrieve a BitmapData which in turn provides me with the
Scan0 property which i then use to loop the pixel data using a byte *.
I am aware of that internally GDI+ stores RGB as BGR,
therefore i have to manually swap the R and B components of each
pixel.
Since GDI+ internally stores the components in BGR order, there is'nt a
way to copy the entire pixel data...

Is there some way to convert a Bitmap from one PixelFormat (16bit or with
indexed colors) to another(24bit), without doing per pixel operations?

Hello!
My goal is to develop a program that opens a bitmap, copies its pixels
to an ArrayList in order to perform some complex calculations (edge
detection, Hough transform etc.), and save resulting image back in some
other bitmap.
It works pretty fast, except for stages of coping pixels between bitmap
(object of type Bitmap) and the ArrayList. I'm using the trivial

Hi All,
I have some Windows BMP, 1BPP, monochrome files that I need to get the
raw data from to load a graphics buffer on a Roll Printer (which I
know can be done). Lets forget about the Roll Printer in this equation
as I am not sure I am getting the correct "raw" image from the file.
However, when I print what I think is the raw data, I get the image
size, but the information within the image looks nothing like it
should be, and...

Dear forum friends,
With the development of smart home technology, a variety of wireless communication protocols have appeared on the market, such as Zigbee, Z-Wave, Wi-Fi, Bluetooth, etc. Each protocol has its own unique characteristics and advantages, but as a user who is planning to build a smart home system, I am a bit confused by the choice of these technologies.
