Title: Conversion fail – size rounding error? | Bug on 2.6 Last modified: August 22, 2016 --- # Conversion fail – size rounding error? | Bug on 2.6 * Resolved [scheeko](https://wordpress.org/support/users/scheeko/) * (@scheeko) * [11 years, 4 months ago](https://wordpress.org/support/topic/size-rounding-error/) * I’m having an issue with retina file generation in 2.6. If I attach an image 2000×1333 if fails for my largest size (1000pixel wide, therefore half the size, so height would be 666.5>667): * ``` 2015-02-03 10:56:52: ** RETINA INFO FOR ATTACHMENT '2015/02/Laguna-de-los-tres.jpg' ** 2015-02-03 10:56:52: - Original: Laguna-de-los-tres.jpg 2015-02-03 10:56:53: - thumbnail: /wp-content/uploads/2015/02/Laguna-de-los-tres-200x200.jpg -> /wp-content/uploads/2015/02/Laguna-de-los-tres-200x200@2x.jpg => RESIZE 2015-02-03 10:56:53: - medium: /wp-content/uploads/2015/02/Laguna-de-los-tres-500x333.jpg -> /wp-content/uploads/2015/02/Laguna-de-los-tres-500x333@2x.jpg => RESIZE 2015-02-03 10:56:53: - large: /wp-content/uploads/2015/02/Laguna-de-los-tres-1000x667.jpg -> /wp-content/uploads/2015/02/Laguna-de-los-tres-1000x667@2x.jpg => FAIL ``` * The 1000×667 is generated ok, but it fails on 1000×667@2x. This did not happen before v2.6, as I have used this aspect ratio frequently before. * If I crop the original image to 2000×1330, then it generates both a 1000×665 and 1000×665@2x perfectly. So maybe it’s related to the rounding of the 0.5 pixel? * Thanks * [https://wordpress.org/plugins/wp-retina-2x/](https://wordpress.org/plugins/wp-retina-2x/) Viewing 8 replies - 1 through 8 (of 8 total) * Plugin Author [Jordy Meow](https://wordpress.org/support/users/tigroumeow/) * (@tigroumeow) * [11 years, 4 months ago](https://wordpress.org/support/topic/size-rounding-error/#post-5745836) * Actually I believed I experienced this issue with previous versions as well… I didn’t change it in the new version. Give me a few days, I am going to replicate exactly your image sizes and photo sizes. I must fix this 🙂 * Thread Starter [scheeko](https://wordpress.org/support/users/scheeko/) * (@scheeko) * [11 years, 4 months ago](https://wordpress.org/support/topic/size-rounding-error/#post-5745837) * Hello Jordy, Thanks for the response and there’s no rush! * Just to give a little more info, since I’m sure there’s _something_ going on now, that didn’t happen before. Another [image](http://blog.scheeko.org/wp-content/uploads/2013/09/The-Cape-212.jpg) with the same dimensions (2000×1333): * I went to the plugin and regenerated the retina files and it generated a 1000 ×666 file (the @2x, again failed). But when I check what’s on the server from an older usage, the files there were 1000×667 and 1000×667@2x. * There’s clearly something happening with that rounding too (although I don’t understand why the conversion fails). I also wonder if it’s related to some other software or code that’s doing the actual resizing (sorry, I didn’t actually go and investigate what your plugin is doing). * Thanks, F * Plugin Author [Jordy Meow](https://wordpress.org/support/users/tigroumeow/) * (@tigroumeow) * [11 years, 3 months ago](https://wordpress.org/support/topic/size-rounding-error/#post-5745902) * Definitely a rounding issue. The calculation of the retina image is based on the new images created by WordPress, which are themselves based on the images uploaded by the users. There was often a difference between what the plugin expects and how the images are resizes by WordPress so now the plugin allows a little error margin (2px max). * I did some testing myself and it seems to work perfectly. Please give me one or two days and the next release should work much better for you 🙂 * Thread Starter [scheeko](https://wordpress.org/support/users/scheeko/) * (@scheeko) * [11 years, 3 months ago](https://wordpress.org/support/topic/size-rounding-error/#post-5745904) * Thanks!
