Gif resizing down increases file size about kirby-focus HOT 4 CLOSED

Thanks for reporting.

The Focus plugin IM driver inherits most of its logic from the original IM thumb driver of the Kirby Toolkit, including the -resize option.

Could you please verify, if the issue also occures when you are using crop() instead of focusCrop()? In this case it is a Toolkit issue, too.

I will check your suggestion, but this will take some time. In the meantime you can change the option by yourself to do some tests, if you like. You can change line 32 in site/plugin/focus/drivers/im.php, which is responsible for the focusCrop() method. There are two more lines with -resize below for crop() and when the image ratio doesn't change.

Thanks so much for getting back to me promptly.

I have just run a quick test and it appears to happen using the crop() method as well. I tried previously altering the im.php file to change the -resize option to -scale, but also no luck.

From a bit of research it appears to be caused by the fact that IM is incapable of optimising resized gifs, which is a shame, and some suggestions seem to prefer other image drivers (eg Gifsicle), which is also not much help!

Let me know if you have any other ideas! Thanks again.

Alright. Thanks for the quick response and the testing.

Seems to be an ImageMagick issue, so I will close this one here.
