If I have a BufferedImage which has
Height 25 pixels
Width 5 pixels
And I scale it so that it is displayed as square (25 x 25), how are the
pixels along the left edge and the right edge of the image determined for
bilinear interpolation?
In more detail:
To make my tall thin image square, I do this:
g2.scale(5, 1); // scale by 5 in x, leave y alone
g2.drawImage(myImage, 0, 0, this);
So one column of pixels from the orig buffered image is displayed as 5
columns of pixels in the scaled image.
I would expect that in the scaled image, the 'middle column' of each 5
column band would correspond to a single column of the original image.
I would also expect that the four columns of the scaled image between each
of the 'middle columns' would show values 'between' each of the middle
columns.
But how would the two columns on the far left and the two columns on the far
right of the scaled image be determined?
Thank you,
Ted Hill
