wxWidgets Discussion Forum

I have a byte array containing the "raw" data (i mean: the pixels) of a 4-bit-per-pixels grayscale image. I receive this data via RS232 from an old device and i can't change this. But I need to draw this image on a wxPanel.

I have an old code made with C++Builder 2006 which initialize a DIB bmp with a 16 color palette, and then it memcpy the array in it each time i receive a new image, convert to screen bpp while scaling it x3 and finally show it on the screen.

I need to do this with wxWidgets (and make it working in both Windows and Linux) but i'm struggling to find how to do the same.

How could i show that array of bytes as an image using wxWidgets 3.0.4?



Thanks.

Create an empty wxBitmap with the correct size and use raw bitmap access to write the RGB data into it:

(You have to convert it to 24bit RGB).
