FIT 14.5.1 – Web Accelerator vs BigimageBack to overview
This month’s release is mostly a “smoothing” release comprising a lot of bug fixes and smaller improvements, as well as 3rd party updates and security patches.
One of the most common errors that we have encountered in our log files was a complaint about source images being too large:
… image area exceeds limit of 8 Mpixels. Of course, 8 million are a lot of pixels. But with the proliferation of high resolution cameras (in smartphones) and high density displays (also in smartphones), prepare to encounter large images in Web sites more frequently. However, the worst part of the error message was:
Continue with original source. That means that of all things the largest images on your Web site are “too large to optimize”. The client has to load all these big files as they are. Even if those might be the outliers of your image files, a single large image with megabytes of data will outweigh every little byte saved by thoroughly optimizing everything else.
Acknowledging this problem, the Web Accelerator now supports sources images with up to 100 mega pixels.
Image Scaling will drastically reduce the file size of large images by allowing optimizations such as format conversion or lossy compression. On our systems, we have seen savings of multiple mega bytes per image. To mitigate the operational costs of processing huge pixel arrays, images with more than 8 mega pixels are processed with an algorithm that is less precise but faster than our usual scaling method. Given so many pixels, there is no noticeable difference.
