Thanks for your suggestions. I've got it working. Here is the essential code. //Define parameters TMemoryStream* Bitmap = new TMemoryStream(); unsigned char header[54]; unsigned char cameradata[262144]; unsigned char imagebtmp[786432]; //Create header & test data //The header is 54 bytes long...

I don't think ScanLine will help me. If there was a function that allowed me to write a line at a time that would certainly help. The image I want to get onto the canvas is not in a bitmap format. I don't know if there is any benefit in converting the data into a bitmap first and loading that?

The data source is a CCD camera, which generates a stream of 262144 data values. This is to cover a 512x512 pixel source. I'm trying to view the camera image on the GUI as fast as possible. I've created an Image1 on the GUI (width 512,height 512). I update the image pixel by pixel using the...

I am looking for a method of updating an Image rapidly from data stored in a 2D matrix. I currently use the following code for each pixel: Image1->Canvas->Pixels[x][y] = greyscale; My image is a 512x512 array so the above line is part of an embedded for loop that iterates 262,144 times to...
