Hi! I need someone who is very good with maths to help me with this, unfortunatly I suck at maths so that someone can not be me. Ironically before I started my first computer course years back I asked the instructer if "learning computers needed a lot of maths...she said 'no, just basics'"..that aint really true is it? :-D
Anyway, I have 2 scripts, one that resizes an image according to the height and width i specify and another that cuts a w=90 h=120 thumb from *within* an image according to the x and y parameters I send it. This functionality is distributed in 2 scripts. Heres my maths problems in 2 parts: Problem 1) I need to scale down an image (eg: example.jpg) to height of 120 pixels while maintaining the images proportions. eg: if i have an image of (height and width) 800x600 what would the dimensions be if the height was 120? usually for resizeing I just do something like this: if($image_height > 400) {$image_height=$image_height / 2; $image_width=$image_width / 2;} which gets me a pretty decent image....but now I need an image no more than 120px in height with a proportionate width. Problem 2) After getting the above image now I need the x and y parameters to cut a h120 x w90 thumb *from the center of the image* eg: if from problem 1 the result is an image of 120 x 160 then x=35 and y=125 (I think, i told you i suck at maths.. :-D ) Anyone up to the challenge? or just want to help a poor person with some maths?
