The Vuescan standard edition is ok value for a scanning application but includes updates for only a year, which might be a problem if you upgrade your scanner or operating system. I do not know if Vuescan or Xsane use colour profiles for the monitor. If you correct during the scan, based on the preview, you need your monitor colour calibrated. I may experiment if I have photographs with colour problems. For 8 bit scans, you need to correct colours and contrast in the scan to preserve the 8 bits of colour for the final image. When you have a 16 bit colour depth instead of an 8 bit colour depth, you can afford to accept small colour errors during the scan then fix the colours during editing. Some of the options appear to be useful for correcting problems during the scan. Xsane also has a few options I have not tested. The Vuescan Pro version adds some settings that interesting. The Standard version appears to do everything I need for photos. OCR is the other major feature in the Pro version and I do not need OCR. The Vuescan Web site says the Pro version has film scanning but the demo has film scanning in both versions. You can download a single installation file and test both for free. Vuescan sells a "Standard Edition", US$59.95, and a "Professional Edition" for US$119.95. GIMP happily opened multiple files and does not have the memory problem that occurs in Simplescan. For most of my scans, I returned to Simplescan to produce PNG files then opened the files in GIMP. The Xsane problems occurred when using Xsane through GIMP. Without changing applications, you can immediately create images in different sizes and formats for display on smartphones and Web sites. You can trim the edges of the scan then save the full resolution scan as a PNG file. This is useful when you place several smaller photographs in one scan. GIMP provides a friendly user interface and places the scanned image in an editing window, ready to trim then save in a format of your choice. GIMP, the GNU Image Manipulation Program, can scan using Xsane. They may occur with only some scanners and be fixed in later releases. There were problems with the version of Xsane I tested. I decided it is easier to use Xsane through GIMP. The Xsane user interface was not obvious at first. Xsane appears to do everything I need for photos. Xsane lists 4800 dpi as an option in flatbed mode and has a transparency mode I have not tested. Xsane is a front end for the Linux Sane scanning software. Big PNG files create problems with the default image viewer in Linux Mint, the only problem I found with the PNG format. The PNG format works beautifully with GIMP and Pix, the two applications I use most. The PNG format works in every image viewer and every image editor. I save the scans as PNG files to ensure there is no loss of detail from the scans. My notebook is due for replacement and the next notebook will have at least twice the memory, removing the memory problem for most of my scanning sessions. I switched to using a desktop machine with more memory. On my notebook with large photographs, I had to restart Simplescan every third scan to free up memory. Simplescan locks up memory without reusing it. If you get the mixture wrong, you can end up with multiple documents mixed up in the wrong file. when you have several documents scanned, you can select individual documents and save or delete them. You can scan several documents then save them one at a time or as a group. I use Simplescan when I do not need the maximum resolution. Simplescan is a common scanning application on Linux but shows only 2400 dpi as the maximum scanning resolution, not the 4800 dpi available from my 9000F Mark II. As an example, simplescan does not support all the resolutions of my scanner. The alternatives may not support odd models of scanners or all the features of your scanner. There are excellent free open source alternatives to Vuescan. The Canon 9000F Mark II shows up as device "pixma:04A9190D". Testing against Linux Sane version 1.0.25 using applications Simplescan 3.20.0 and Xsane 0.999. Testing with a Canon 9000F Mark II with USB ID 04a9:190d labelled "Canon, Inc. All the software tested here is faster than the scanner. Testing VueScan 9 圆4 (9.5.76) in Linux Mint 18.1 on a machine with a medium speed processor and a fast SSD.
