Question

You are to read in two pixel values and generate a number of pixels specified between them. Using the 2 pixels specified it will generate 3 new pixels between the first and last pixel. You will need to round the difference of each channel between the larger and smaller pixel.
Example ：
Enter the first pixel: 0x002222
Enter the second pixel: 0xFFDD33
Enter the number of colours to generate inbetween: 3
Colours:
0x002222
0x405126
0x80802a
0xc0af2e
0xffdd33
How to deal with problem like this !
Thanks in advan

Answer 1

In linear interpolation it is really easy. You just have to calculate the RGB differences of the start and end pixels, respectively. For each color its own difference.
Then, assuming that the start pixel is 1, end is 5 and you are looking for color coordinates of 2, 3 and 4, here's what happens:

2 gets the color coords of 1 boosted by 25% of the differences, 3 get 1 + 50% of the diffs and 4 gets 1 + 75% of the diffs.

Of course, that is best done in the hexadecimal mode :)
