Problem resizing graphic (reducing size) - 8/21/2005 16:35:38
I have a problem with a graphic (a logo) on a site that I'm redesigning. The original graphic is a jpeg (516 x 333px and 300 px per inch). I've been using it on the previous version of the site at 150 x 98px, still as a jpeg and it looks okay-ish.
With the new site though I'm trying to reduce the size of the top of the page to get more content 'above the fold'. I've been trying to reduce the image to 75 x 48px and I looked back through previous posts that suggested reducing the dpi and using bilinear resizing (I'm using PSP8 btw). I've reduced the resolution to 72dpi and resaved as a gif.
By doing that it doesn't look too bad in PSP, though a little pixellated (though I have to have it magnified quite high so I can see it clearly), but when i view it on the web page it looks extremely pixellated and kind of squished and elongated (and yes I have remembered to change the height and width attributes in the code). I've no idea what's wrong here. Can anyone suggest anything I might be doing wrong?
Thanks. W

Ok - now don't yell at me... I know you changed the dimensions in the code, but did you change the file name from photo.jpg to photo.gif? I only say this because I've done this before now plus the "always good for a laugh" forgetting to upload the new image to the webserver so the page just finds the old one.

womble : do you still have the original (516 x 333px and 300 px per inch)? sounds like you rediced that once and are now working from the reduced version. remember that .jpeg is "lossy" and each time it is saved, more data is lost. I suggest going back to the original or aas close as you can get. also, personally, i have never had luck going from jpg to gif. if it were me i would stick with the jpg

could you post a link to the original?
also when you resize you can take it down 50% use unsharp mask (not *too* much) then take it down to the exact dimensions. if you can you can reduce it to 25% of its original size first.

Dan - she's got a stylesheet switcher so the background colour will be changing.

I was going to suggest png format, but IE has problems with that I think - Tail?

It does have problems with png transparency. There are ways round it with scripts but frankly could never be bothered to experiment! Aparently IE7's fixed that. So it'll only be another 10 years until we can forget all the legacy browsers that do have problems *sigh*.
If it's causing a major problem then you could always have different logos with different colour backgrounds as background images for the header div (or whichever) on the various stylesheets.

yeah i know ;)
if you notice when you zoom in or out in factors of 2 (say 50% or 25%) that the image is smoother and clearer than it is if you say zoom to say 67%...
