Bulk Upload: Image changes size from the original after bulk uploading

[natechadwick]

As we can see, the original file is around 1.17 mb whereas after upload the size is now 225kb.

@matomario8 Is the issue on this one that they can't configure the compression ratio / toggle if the image should be compressed?

It looks like the code for this is controlled by system/Tools/ImageWidgetService/src/com/percussion/widgets/image/services/impl/ImageResizeManagerImpl.java. Depending on the file type, image assets are automatically compressed, but there is no configuration option for the compression parameters like compression ratio etc. I think the bulk upload tool would need an advanced option to set these options per file with configurable system defaults for each image type to cover cases where compression isn't wanted.

There are also two extensions that handle the image processing, they are:

• https://github.com/percussion/percussioncms/blob/development/system/Tools/ImageWidgetService/src/com/percussion/widgets/image/extensions/ImageAssetInputTranslation.java

• https://github.com/percussion/percussioncms/blob/development/system/Tools/ImageWidgetService/src/com/percussion/widgets/image/extensions/ImageAssetOutputTranslation.java

This is an example of what is currently done for jpegs:

            if (result.getMimeType().equals("image/jpg")) {
                log.debug("Compressing a JPEG");

                iwp.setCompressionMode(2);
                iwp.setCompressionQuality(this.compression);
            }

CompressionMode for example is hardcoded. These would need changed to make the compression configurable.
