QPV is able to create image slideshows and cache very large dynamic lists of files. Unlike other applications of this kind, it can load, on my system, a list of 900100 files in under 10 seconds, while XnView Classic or Irfan View needed more than 15 minutes, back in 2019 when I began developing this image viewer, on the system I was running. The index of files can be saved as plain-text or as an SQLite database.

With Quick Picto Viewer you can generate file statistics over huge image libraries which can help identify very small images, very low key, or washed out images. You can also identify image duplicates and auto-select files by given criteria.

QPV also has specific tools to index image contents and identify image duplicates, based on similarity. Users can choose from four algorithms to identify the duplicates.

Quick Picto Viewer is also able to play sound files associated with images, automatically or on demand, and even generate slideshows that are in synch with the audio files duration. Supported audio formats: WAV, MP3 and WMA. It can also display image captions / notes for image.

QPV can be used to edit images and/or paint new images. Various tools to this end are available, including blending modes and alpha masking abilities. Please see the features list to learn more in details what QPV can do.

Since v6.0, QPV can open images of up to 10000 megapixels or more. Most of the available image editing tools work on such large images.

Image editing:

  • Options to control viewport brightness, contrast, saturation and RGB color channels balance/intensity.
  • Adaptive auto-adjustment of brightness, contrast and saturation of displayed images.
  • Images can be rotated or mirrored horizontally and vertically in the viewport.

    • ability to randomize various brush properties when painting
    • textured brushes
    • paint with symmetry
  • Image editing tools:
    • draw arcs, lines and filled shapes
    • parametric line generators [grids, spirals, rays and more]

  • Vector shapes can be defined with symmetry on X or Y axis.
  • Ability to save/load user created vector paths.
  • 18 blending modes and alpha masking support implemented for various image editing tools.
  • Alpha mask can be user painted or generated: a gradient [linear, box, radial] or a previously drawn vector path.
  • Advanced yet easy to use auto-crop for images.
  • Real-time histogram for any image color channel of the image displayed.
  • Easy to configure viewport grid.
  • Paste texts from clipboard and render them as images. Text and background colors, font style, alignment and size can be personalized.

Files management

  • Omnibox and folders tree view - two specialized panels meant to help users navigate through folders, with support for drag and drop amongst them.
  • Quick file actions. Easily move or copy files to user defined folder paths using the number keys: 1 to 6.
  • Ability to automatically group files into sub-folders based on file types or modification date, by months or years.

Other details

Quick Picto Viewer was developed with special attention for people with disabilities.

I coded the application as an AHK script for AutoHotkey_H v1.1.33. To execute or compile the source code one needs AHK_H, also mirrored on my Github repository.
