XSane development

XSane is a graphical scanning frontend for the SANE-library. This page is dedicated to some enhancement patches for XSane.

• Scale to a given output width and height:

  original (xsane-0.85)	patched
  The xsane-viewer of a scanned image gives you the possibility to scale the image according to given x/y scale rates.	The scale menu is enhanced of the resulting output width and height values. If you change the output width and height the scale rates are adjusted accordingly.

  Download:
  • patch-xsane-0.85-scale_to_output_width_height-0.1 ( 9 Kb, 22. April 2002): First running version.
  • patch-xsane-0.85-scale_to_output_width_height-0.2 (13 Kb, 24. April 2002): Use output widht/height as refernce (instead of scale_factor).
  • patch-xsane-0.85-scale_to_output_width_height-0.3 (26 Kb, 29. April 2002): Add cubic interpolation as scaling algorithm. See the example: The original image and two 8x zooms, one time with the original XSane scaling algorithm and the second time with the cubic interpolation scaling algorithm.

    original image	8x zoom: original scaling algorithm	8x zoom: cubic interpolation algorithm

  • patch-xsane-0.85-scale_to_output_width_height-0.4 (22 Kb, 03. July 2002): Get rid of allocated tmp_row.

• Do the selection of the scan area in the preview with a given proportion. The selection will be determined by a given proportion, say 4:3 ( for a resulting scanning which will then scale nicely to a 1024x768 output image) or 1:1 for quadratic results.
  • patch-xsane-0.85-preview_proportional_selection-0.1: First running version.
  • patch-xsane-0.85-preview_proportional_selection-0.2: This one uses a patched gtk library (patch-gtk+-1.2.10-gdk_window_set_pointer-0.1) to bound the mouse pointer to allowed positions.
  • patch-xsane-0.85-preview_proportional_selection-0.3: A lot of bugfixes. Needs patched gtk library.
  • patch-xsane-0.85-preview_proportional_selection-0.4:
    • Fix bug when preview is rotated.
    • Fix bug when view update last to long and new button move events from old pointer position are queued.
    • Fix wrong moves on button pressed event without move.

    Needs patched gtk library.

  • patch-xsane-0.85-preview_proportional_selection-0.5 (27 Kb, 22. April 2002): Another approach to the event queue problem. Try to get the last timestamp which was processed by the X server. This one needs a patched gtk library (patch-gtk+-1.2.10-gdk_window_set_pointer-0.2 (3 Kb, 22. April 2002), plus the function gdk_window_last_timestamp_processed).
• XSane had a problem when saving images with more than 8 bit per pixel as jpegs. This patch fixes the problem with converting the image data to 8 bit values before calling the jpeg library.
  • patch-xsane-0.86-save-as-jpg-0.1 (2 Kb, 08. May 2002).
• Add the filename counter feature to the Viewer mode of XSane.
  • patch-xsane-0.86-viewer_with_filename_counter-0.1 (2 Kb, 28. June 2002).
• The original XSane has an extra phase when the scanned image is rotated (scan->save->read->rotate->save). This patch gets rid of the extra rotation phase. The scanned data is directly stored with the rotation/mirroring into the output file (scan->rotate->save).
  • patch-xsane-0.85-scan_and_rotate-0.2 (4 Kb, 03. July 2002).
  • patch-xsane-0.85-scan_and_rotate-0.3 (4 Kb, 06. July 2002): Bugfix for 16 bit color depth.
• Show the red, green and blue values of the pixel where the cursor is in preview.
  • patch-xsane-0.85-show_rgb_values-0.1 (4 Kb, 03. July 2002).
  • patch-xsane-0.85-show_rgb_values-0.2 (6 Kb, 03. July 2002): Show values for raw and enhanced image.

Binary download (linux i386)

If you want to test a patched version of XSane you can download here a binary version with the gtk libs statically linked (build on SuSe-7.0-i386).
