 |
|
Hi all,
I am rendering a synthetic image/graph and want to plot this image on the
form. The image is rendered on a buffer as a 24-bit RGB bitmap.
Its been a while since I used Borland C++ builder, but now with the release
of Turbo C++ I'm trying to get back on my feet with C++ Builder and VCL.
Thanks,
IraqiGeek

How would a buffer with as content a 24-bit RGB bitmap differ from a
Graphics::TBitmap with the same content?
Did you experiment with Graphics::TBitmap already? There are actual
examples in this group.
Maybe the thread 'TBitmap and HBITMAP question' is usable for you?
If you just read all the posts here you could make your problem
more concrete.
Once you have your picture in a Graphics::TBitmap displaying it is easy.
Hans. |

Look at the windows API function SetDIBits().

I really dont know as I am not familiar with Graphics::TBitmap. I am
extracting color image data from DSLR RAW files (originally 12-bit per
color, but scaled down to 8-bit/color) into a char buffer (with the buffer
x-axis being 3 times the number of pixels to accomodate the RGB data). Now I
want to show the final result of my processing into a Timage and/or save it
to a .BMP file.

Yes I did. However, I didnt get how to actually copy the image I have on my
char buffer into the TImage.

I really don't know. I haven't used BC++ builder for over two years, but now
with the release of Turbo C++, I'm getting back to Borland, but I feel a bit
lost in the UI and in finding help/documentation.

Yep, but how do I get my buffer contents to Graphics::TBitmap???

ISTM that if you're extract the rgb data that you can easily
extract it directly into the TBitmap's scan lines. All you'd
need to do first is set it's PixelFormat and it's Width and
Height.
Read the Bitmaps Again thread. It explains how to work with
the scan lines depending on the pixel format.
