Question

jpg size

asked on August 30, 2017

When importing jpg files to Laserfiche, shouldn't they come in at the same size?  I'm not sure why 35 GB worth of images (engineering drawings)  ended up being 135 GB when I exported the briefcases.

Since briefcases are generally used to transfer documents between repositories my guess is its transferring additional information as well as the images. An additional 100gb seems excessive for just that tho, are you using version tracking, if so you could be effectively exporting multiple of each image.

I don't think that it is the briefcasing that is causing the size issue.  We transfer files as briefcases a lot and have never had this size discrepancy.  I think the issue is when the jpgs are imported into Laserfiche.  I think that Laserfiche uses a different compression method which causes the Laserfiche Tif images to be much larger than the original jpgs.  Does this make sense?  Thanks!

You can compare the size on disk with the imported size by looking at the Page Info tab in the document's properties.

Yes, I know that.  I'm just wondering if Laserfiche changes the compression on import.  Thanks.

yes, they're saved as TIFF LZW, controlled by the [Options]DefaultColorFormat attribute. Possible values: 2 (Gif), 3 (TIF), 6 (BMP), 10 (JPG), 11 (TIFF_JPEG), 17
