I got it :-)

Alpha Blend function apply the transparency to all pixels. What i want is, I have the pixel array containing the RGBA (RGB and Alpha)values consequently. I want to apply the alpha value for each pixel.
For that I am using BITMAPV4HEADER and SetDIBitsToDevice function to draw the pixel array into picture box. But the Alpha value is not working (RGB is working fine).
How can i use alpha value??

Iain,

Are you aware of Alpha Blend function?
I want to draw the Transparent BITMAP, As said earlier i have the pixel array that containing the RGB and Alpha value. But transparency not happening..

Regards,
Rajesh.

Jochen,

I am containing the pixel array containing the RGB and Alpha value. I can able to plot the RGB values in display, but Alpha (for transparency) is not working. How can Implement this?

I am using setDIBitsToDevice function to plot the pixel array into display.

Rajesh.

Put your code here.

Iain,

I solved It:-)
Thanks for your co operation.

Iain,
Still problem is there.
If you don't mind, give your email, I will send the Outputs (what exactly I want & what I have now). Otherwise Can I upload the image here?
The problem is, I got the picture, but some alignment problem is there.

Iain,
One more doubt,
As said earlier, I have the pixel array (24 bpp format & 1024x1024) contains the RGB values, but It has no padding byte values.
How can I add Padding Bytes (24 bpp format) into the pixel array?

Iain Clarke,
Thanks for your previous quick reply.

Bitmap pixel format have the color format in the order of blue, green, red.
I am containing the 2D array, which contains the value in the order of red, green and blue.
When I am print the 2D array, the color pattern is not look like what I want.
How can I map the My RGB format to BGR?

Iain Clarke,
I think you understand my question.
I have only a 2D Array (1024 x 1024), which contains the RGB colors.
My question is, I want to plot these array of pixel into picture box or bitmap, whatever at a time, Now I am using loop for drawing the same, It take more CPU utilization.
But, In SetDIBitsToDevice, We can copy the from a bitmap to destination, Am I right?

Rajeshkumar Ramasamy 15-May-13 2:11am View

Are you have any example for SetDIBitsToDevice?

I have inserted a Form (CFormView) in MFC Mainframe. In that form, when i am going to repaint, at the time flickering happen. For that i will have to use EraseBackGround (in false mode) function. But in the form's class wizard WM_ERASEBKGND is not available. So how can i include EraseBackGround function in that form?

Sergey, I want to draw (pixel by pixel) in a form. It take time to draw pixel by pixel (range : 1024 x 1024). Any Tools/Controls are there for draw?

Rajeshkumar Ramasamy 21-Mar-13 0:29am View

Any Controls are there for drawing, Instead of draw pixel by pixel.

Yes, IDC_PICBOX is child window of CSplitterOne class.

Rajeshkumar Ramasamy 12-Mar-13 8:09am View

I had Create same form using Splitter Window. I have to call the OnPerformIBIT() function from MainFrm.cpp. I am not got the handle when I am calling from MainFrm.cpp, If I put the same function from OnPaint & OnInitialUpdate, it works. How can i get the window handle if i'm call from Mainfrm.cpp?
