Webdesign:PHP:How to Resize Image Dynamically in PHP
Sjabloon:Ays:blockfloatDownload timthumb.php and put under any folder. Upload this script timthumb.php though FTP to your web hosting. Put it under a directory /script. Just call timthumb.php with appropriate arguments, For example: <img src="/script/timthumb.php?src=/some/path/myimage.png&w=100&h=80" alt="resized image" /> Code language: HTML, XML (xml) And that’s all!!
One thing worth noting here is that this library will create a folder cache in the directory where timthumb.php script resides. This folder will cache the resized image for better performance.
You can refer following table for different parameters and its meaning. Parameter Values Meaning src source url to image Tells TimThumb which image to resize w width the width to resize to Remove the width to scale proportionally (will then need the height) h height the height to resize to Remove the height to scale proportionally (will then need the width) q quality 0 – 100 Compression quality. The higher the number the nicer the image will look. I wouldn’t recommend going any higher than about 95 else the image will get too large a alignment c, t, l, r, b, tl, tr, bl, br Crop alignment. c = center, t = top, b = bottom, r = right, l = left. The positions can be joined to create diagonal positions zc zoom / crop 0, 1, 2, 3 Change the cropping and scaling settings f filters too many to mention Let’s you apply image filters to change the resized picture. For instance you can change brightness/ contrast or even blur the image s sharpen Apply a sharpen filter to the image, makes scaled down images look a little crisper cc canvas colour hexadecimal colour value (#ffffff) Change background colour. Most used when changing the zoom and crop settings, which in turn can add borders to the image. ct canvas transparency true (1) Use transparency and ignore background colour Hope this is useful for you :)
