Summary: | 0001351: Pre-resize image to speed up page loading | ||||
Description: |
It's obvious, that users upload images in a higher resolution, then actually is needed on a website and they needs to be resized. Right now to speed up uploading process In-Portal don't resize image right after uploading, but only at time, when it's displayed in a different resolution on a website. This seems to be very good solution when: * small amount of users tries to view a page with image thumbnails displayed; * images were originally uploaded in low resolution (smaller then 1MB on size). But in case when a lot of users tries to see page with resized images at a same time and original images are ~4MB+ in size, then it will take a lot of memory and will attempt to resize same image multiple times. In-Portal don't pre-resize images in background, because it can't guess what image dimensions would be requested in actual theme, user set's as primary. But I have an idea, how to overcome that: Create new column in Theme table, called ImageResizeRules, where per-path image resize rules will be written in following format: * /system/path/one/:format1 * /system/path/two/:format2 Usually each line would look something like this: /system/images/manufacturers/:resize:100x75;default:img/no_picture.gif Actual data to place in ImageResizeRules field of the theme database table will be retrieved from <image_resize_rules> node in /_install/theme.xml file of individual theme. Then CRON script would scan all rules from each theme and pre-resize images according to them. Even more, if we would consider using Message Queuing servers, like ZeroMQ, then we could schedule resize jobs right after image was uploaded. |

Steps To Reproduce: | |||||
Additional Information: | Also need to create "Settings" field (textarea) in each Agents/Scheduled Task. In context of this discussion this field can be used for specification of image resize settings described in original post. | ||||
