JPEG - Quality

[fredrik_76]

Hello vger,

 

There was no problem installing, everything works fine. My problem is that the thumbnail have very low quality, so I combined some code from your contrib 3423 with sime lines from contrib 1484. That worked great, the original pics are 50-80KB, with your contrib the thumnails is 2-4KB in size and now with the code from contrib 1484 the size is 8-12KB. My problem is that the quality is still to low for us. I will try modify the code from Contrib 1484 so the quality can be more than 100. 200 makes the same size thumbnail as 100.

 

This is the code, it is not written by me:

# Added possible definition of JPG thumbnail quality

# Changed number of steps for this contrib

#

#IF you are UPDATING and need to add the jpg quality only, do this (complete INSTALLATION instructions below):

#open /catalog/include/functions/html_output.php

#search for

# function thumbimage ($image, $x, $y, $aspectratio, $resize, $cachedir){

#directly after add

# define(JPEGQUALITY, 95); //define the quality of JPG thumbnails

#search for

# call_user_func("image".$types[$imagedata[2]], $thumb, $cachedir.$thumbfile);

#replace with

# if ($types[$imagedata[2]] == "jpeg") {

# call_user_func("image".$types[$imagedata[2]], $thumb, $cachedir.$thumbfile, JPEGQUALITY);

# }

# else {

# call_user_func("image".$types[$imagedata[2]], $thumb, $cachedir.$thumbfile);

# }

#UPDATE done
