I'm running Win2003 R2 x64.
From VS 2005 i created a new Win32 x86 project and pasted the code in the WM_PAINT case.
My gdiplus.dll's are:
C:\WIN\WinSxS\amd64_Microsoft.Windows.GdiPlus_6595b64144ccf1df_1.0.3790.1830_x-ww_56CDF238\GdiPlus.dll File Version: 5.2.3790.1830 (srv03_sp1_rtm.050324-1447)
and,
C:\WIN\WinSxS\x86_Microsoft.Windows.GdiPlus_6595b64144ccf1df_1.0.3790.1830_x-ww_24C40C58\GdiPlus.dll File Version: 5.2.3790.1830 (srv03_sp1_rtm.050324-1447)
...cmk

I was afraid of that too LOL
Mine is XPSP2 gdiplus.dll is 5.1.3102.2180
Where is the mythical GDI+ 1.1 ...
Thank you!

Hello Gentlemen!
I am working on a project in vb.net. The application will color any grayscaled picture in its actual colors. The problem is big!
All I need is an accurate advise or direction how to setup an algorithm to find the exact colors of the picture.
It seems to me that I have to find the color of each pixel first and then what? Is there any matrix about the colors what reflects a paralelism between graysacaled color set to others.
Any advise would be helpful..
Thank You!

I don't think you can get exact colors from a grayscale image.
Have you searched for "colorize algorithm"?

there is no way to find the "exact color" of pixel from panchromatic (greyscale). The primary issue is that panchromatic is usually luminance which follows a ration of RGB light there will usually be more than 1 color value triplet to match each pancromatic pixel.
you are trying to reverse this formula: RGB Luminance value = 0.3 R + 0.59 G + 0.11 B
so if the luminance value is say 255 (bright white luminance) what is the values of R G and B? If you know the most prominant color, a color reference, then you can figure out from the ratios the others involved.

You are very welcome. Always willing to encourage the image processing addiction... you'll hate me later.

It's way too late. My first computer job that's what I did.
The challenge lately has been to not get sucked into it, for the time being
Hopefully soon I'll have someone to do my UI programming so I can get back to the fun stuff!

Thanks you very much Jeffry.
I was intending to pull my sleves and jump into coding but when I examined the sophisticated algorithm behind it, I decided to roll back my sleves...
Thanks a lot!

It is the stuff that master's thesises are written about. I know of about four. none of them mine, sorry. Though my work was turned into a master's thesis, it just wasn't for me, someone used my work to get theirs.

I am programming a small drawing application.
And what I do is rubber band a red circle and draw in black (eventually any color but red). And my program draws designs inside of the circle, and then when the user is done, the user can make a new circle. And I want the circle to erase itself and not the designs it may encounter in the rubber banding. I would like to know how to just erase the circle.
This means I am asking a general mixed mode involving the SetROP2 function in the Windows GDI. Is there a way to draw on a client window and erase only the pen color? (Erase means make it white.)

This has nothing to do with ROP, just draw the circle based on a Boolean flag and when the flag changes issue a command to redraw the area that contained the circle.

Can I select a DIB into a memory Device Context?
If yes, then how?
B2C

No.
The docs for SelectObject[^] explain what can be selected into a DC.
But, you can select a DIBSection into a mem DC. See CreateDIBSection[^]
or you can create a DDB from a DIB with CreateDIBitmap[^]

Are you sure you're not mixing up DDBs and DIBs? If so how does one select a DIB into a
device context?

 I apologize; at one time I was so used to dealing with raw DIBs that I forgot that they needed to be converted to a GDI DIB via CreateDIBSection, which converts a raw DIB to a DIB that the GDI recognizes, before it could be selected into a DC.

No apology necessary for sure. I wonder what happened to the OP?

They often disappear after the original post. Some times they come back and say thanks and other times they just continue on with their lives, with a little more information.
I have been guilty of both! 
P.S. I have been known to disappear for weeks!

Yes! A dib is just a bitmap and if your program can load it you can display it. The problems occur when it is not a dib (essentially a “.bmp”), in which case you will need to convert it using code like “CxImage” (at CP).
See LoadImage (MSDN).

Using DirectX.Capture I lately found out that there is a problem in Lip movement and voice synchronization, i.e. when I apply Video Compression and without applying audio compression, say for example Microsoft Video 1, I found out that the voice and the lip movement does not match, sometime the voice/sound came out after the lip movement or vice-versa. What is the problem with these and how do I solve this problem. I will be very happy to get answer for this query.
Thanks in advance.

Is there a way to import an object created with a 3d-modeling program (ex. Google Sketchup) to an OpenGL application and use it?
If yes what file type must it be (.obj?) and how?
I'm new at this
