PrivateEye
icon
version 2.85 (03-Jun-2008)
PrivateEye is an image viewer. It can load and display both bitmap and vector images: Sprites, JPEGs, GIFs, PNGs, DrawFiles and ArtWorks.
JPEGs are displayed using SpriteExtend's on-the-fly renderer. Inbuilt lossless "cleaning" transparently loads progressive JPEGs.
Bitmap images can have effects applied. Gamma, brightness and contrast can be adjusted. Images may be blurred and sharpened. Saturation and histogram effects may be applied.
Bitmaps can be rotated with interactive preview. Rotation is lossless for JPEGs.
JFIF, Exif and Adobe metadata information may be viewed.
Any number of images may be open concurrently.
PhotoFiler
icon
version 2.08 (05-Feb-2008)
PhotoFiler adds picture thumbnailing features to the Filer. By default it can display thumbnails for Sprites, JPEGs, and DrawFiles. It can also integrate with ImageFS and ArtWorks.
This version is a new release as freeware with the source code included.
Toolbar
icon
version 1.21 (31-Jul-2009)
Toolbar is a pull-down application launcher. It can also run files and open directories. Once an object is launched, it smoothly retracts back into position.
It can be configured to reside on either on the top left or right-hand side of the screen and stores the names of up to 32 objects.
This version includes an uncrunched !RunImage.
QuickFiler
QuickFiler adds many standard keyboard shortcuts to the RISC OS Filer.
It is now maintained by Martin Avison.
Tiling Backdrop Textures
An archive of NewLook-ish seamless repeating textures to use on your pinboard and window backgrounds.

Toolbar 1.21 fixes a crash on RISC OS 6.

July 30th, 2009

After a mere decade's hiatus here's Toolbar 1.20 with a few tweaks.

  • The toolbar now opens and closes independently of desktop speed. So if a greedy process is hogging your desktop, the toolbar will now unfurl and retract in the same amount of time.
  • You can have multiple toolbars, if you fire off multiple instances (it'll use different choices files and position itself independently).
  • The !RunImage is no longer squashed.

Geminus, the Iyonix graphics accelerator, has been re-released as a free download. Its sprite caching provides a substantial speedup for PhotoFiler and its JPEG acceleration greatly benefits PrivateEye.

PrivateEye 2.85 with enhanced transparency and PNG support.

Sprites and PNGs may specify an alpha channel to hold transparency information. PrivateEye can now recognise and display these images using the Tinct module.

Transparent images can be displayed against a checkerboard pattern background.

The effect system now knows about alpha channel data and always preserves it. The curve effect has been upgraded to allow editing of the alpha data.

All these changes are mainly in aid of enhanced PNG support. Now all of the images in PngSuite can be loaded and displayed.

PhotoFiler is now freeware and includes the source code.

PrivateEye 2.75 with JPEG metadata support.

The big new feature in this version is interpretation of JPEG metadata, one example of which is Exif data. The new version of PrivateEye can decode and present this data in a treeview, so you can view (but not edit) the information stored by digital cameras and image processing applications. It also supports Adobe, IPTC-NAA and JFIF COM data.

The other new feature is caching. PrivateEye can allocate an amount of memory in which to preserve recently-loaded images. This saves time when flipping back and forth between files.

I've also made the 'Convert to Sprite' function for JPEGs more accessible, which makes using the histogram and effects system more convenient.

PrivateEye 2.50 had a bug which could stop the effects window working on any OS earlier than RISC OS 4. I was calling Wimp_AutoScroll which didn't exist up until WindowManager 4.00.

Bug fix release 2.51, now available, fixes the problem and also tidies up some vanishing icons in the templates.

PrivateEye 2.50 has effects!

Features:

  • Bitmap effects
    New bitmap effects window allows adjustment of brightness, contrast, gamma, tinting, blurring, sharpening, histogram-based adjustments and more.
  • Editing awareness
    PrivateEye now knows when you've edited images.
  • Histogram
    The histogram window has been freed from the menu structure and can now show you the individual histograms for red, green and blue.
  • PhotoCheck
    Brought across from PhotoFiler, this OS patch enables the versions of SpriteExtend in RISC OS 3.6, 3.7 and 4.0x to cope with a greater range of JPEGs.
  • Customisable keymap
    You can now redefine or supplement the standard key mappings.

  • Rotation.
    Sprites and JPEGs can now be transformed with any combination of 90 degree rotations and horizontal flips. JPEG transformations are lossless.

    JPEGs are now integrity checked when loaded. If they fail the check, they're passed through an internal version of jpegtran.
  • New views.
    You can now have multiple views open on the same image.
  • Luminance histogram window.
