[SOLVED] Displaying only a portion of a graphic image ?

[lxndr]

I have a routine which reads in the names of all the GIF graphic files from a particular directory and displays the actual images but what I want to be able to do is just display a PART of each image.  For example, all of the images are 500 pixels wide by 55 pixels high and I want only to display the first hundred pixels width of the image so that I would in effect have just a portion of each image starting from the left and 100 pixels wide.  Can it be done ?

Yes.

Another way of doing that would be to use the graphic images as the background to a defined area that's 100px wide by 55px high.  You could do that with a series of size-defined divs, but it might be easier to use a table with each cell having a different background defined and a transparent 100px by 55px image as cell content.

Thanks to both of you for the speedy replies, I shall follow up your suggestions.

As usual it's a tradeoff.

 

To resize the image uses server resources

 

To truncate the image on output uses extra bandwidth as the whole image is still sent.
