Not a question. Idea of SetPixel won't work though.

Solution 1

No.
Several reasons:
1) SetPixcel only works with int values - i.e. 32 bit indexes.
2) Even if you could, any operations involving SetPixel over that number of pixcels would be horrifically slow!
3) You can't even create a bitmap that big: 2^32 is 4Gb, and .NET has a maximum individual object size of 2Gb - which means that for practical purposes you can't create a bit map larger that 1 row x 500,000,000 columns.

slowness is not my concern.please is there any possibility to give large x,y values

vishnulalr 11-Jun-11 12:15pm

is there any function other than setpixel(int,int,color);

Read the answer: Not in .NET - you can't create any object that big.
You will have to learn C++ and do it in native code...

thanks for your replay sir

is it ordinary c++ or visual c++ in visualstudio 2008

Doesn't matter. You just cannot use managed code (anything that targets the .NET Framework).

Well, that's not entirely true, you could create the image entirely by writing the data to the file. But, you cannot load the image into a object and display it. You'd have to know the exact layout of the file format you're using and exactly how to write each byte out and in which order to do this.

OP could create zoomed of fragmented pictures dynamically based on, say, data in file...
The site of Hermitage Museum does something like that. The volume of data on each painting is tremendous.

Yeah, he could. But do you get the feeling he knows the file format and knows what he's doing?

Sergey Alexandrovich Kryukov 12-Jun-11 23:24pm

Not really. :-)

All correct, my 5.
