ImageResizer Image Quality

Hi

I was wondering with the latest build of ImageResizer the default image quality is 75% but I need this to change to 100% since im using thumbnails of screenshots and 75% just makes them look real bad.

Im guessing that I would need to modify CachedResize_Image.php but not sure where and what to...

in the PHP manual it states I would add a value imagejpg but there is not reference to that in the code where I can add a value to.

ok i think I found what I needed to change but just wanted to confirm thats all I needed to change:

LINE 207

$process = $image_save_func($image_c, $save_path, 100);

changed to :

$process = $image_save_func($image_c, $save_path);

are there any other parameters that I could change to improve quality of image, or was it just this line?

That looks correct, image quality only applies to jpegs and there is only the one parameter.

I am having the same problem. I need to be able to change the compression amount on my jpg files.

on line 207 my code is already set too $process = $image_save_func($image_c, $save_path);

Do I need to change this?

My images look way to compressed, I am sure that in older versions of this plugin you could set the amount, but I may be wrong.

I am using the latest version to date.

change line 207:
$process = $image_save_func($image_c, $save_path);

to:
$process = $image_save_func($image_c, $save_path, 100);

I tried this and it did re-cache the image as I could see the changes in github, that they had been deleted and added again, but they seem to look the same.
The original images are a lot bigger and a good resolution, so not sure why they are still looking to compressed.

Thanks
