- Visionaire 1.1
- --------------
- February 25th, 1993
-
- Thank you for buying Visionaire. This file contains last changes to
- the documentation and to the program that didn't make it to the
- manual, as a result of the continuous development effort put into
- Visionaire.
-
-
- Additions to the Manual
- -----------------------
-
- NORMAL AND FP VERSIONS
-
- Two different executables of Visionaire are provided, "Visionaire" and
- "Visionaire_FP". The FP version is specially cutomized to take full
- advantage of a 68030 or higher CPU and a 68881 or higher FPU (note
- that a 68040 CPU includes a 68881 compatible FPU). If you don't have
- at least a 68030, however, DO NOT RUN the FP version! Note that if
- you have a lower CPU (like a 68000) and a properly installed 68881,
- the normal version of Visionaire will detect its presence and take
- advantage of it.
-
-
- GRAPHICS MEMORY
-
- You should make sure that you have enough FAST memory free (about 1Mb
- at least) before you run Visionaire. Visionaire will only use
- graphics memory for its data if there is no more FAST memory
- available. When this happens, the performance drops dramatically, as
- a result of current Amigas architecture.
-
-
- 8-BIT ILBM
- 8-BIT SUN RASTERFILE
-
- Visionaire can now output images in two additional formats: 8-bit Sun
- rasterfiles and 8-bit ILBM's. Visionaire uses a sophisticated color
- choosing algorithm, which is combined with Floyd-Steinberg dithering
- to produce convincing 256 color images. The 256 color ILBM's can be
- loaded in compatible software or shown directly on the newest Amigas.
- To use these new output formats, all you have to do is select the
- approrpriate format in the "Output Format:" gadget in the "Animation
- Settings" requester.
-
-
- HAM8
- HAM8 INTERLACED
-
- Visionaire is now able to directly output HAM8 images and animations,
- compatible with the newest Amigas (A1200 and A4000). To use these new
- output formats, all you have to do is select the approrpriate format
- in the "Output Format:" gadget in the "Animation Settings" requester.
-
-
- DITHER
-
- There is a new gadget in the "Animation Settings" requester that
- allows you to select the type of dithering that you want applied to
- the output images. Currently you can choose either "None" (for no
- dithering) or "F/S" (for Floyd-Steinberg dithering). Note that
- dithering is not effective for 24-bit images.
-
-
- AGA CHIPSET
-
- Besides the newer 8-bit (256 colors) and HAM8 output formats, which
- are compatible with the new AGA chipset, Visionaire also allows you to
- open its screen in the newer display modes. It is now possible, for
- instance, to work in an 8-bit deep mode, with your previews using up
- to 256 colors. And Visionaire is able to load HAM8, 256 color images
- or any other mode compatible with the new chip set.
-
-
- DITHERED PREVIEWS
-
- There is a new mode for displaying the previews, "Dithered", that can
- be easily selected in the "Editing Settings" requester. When this
- mode is active, the previews will be displayed in shades of gray, with
- the use of dither to increase the number of shades displayable. The
- custom dithering routines were optimized to obtain high quality
- previews, but with a performance that is still quite acceptable. Note
- that in this mode Visionaire will use less graphics memory (it will
- use more fast memory, however).
-
-
- RESTORE SETTINGS
-
- There is a new menu item in the Settings menu, "Restore". When this
- item is selected, Visionaire will restore the settings to their state
- before the last change you made. You can choose this item after you
- have used wrong values in one of the Settings requesters, or if you
- have loaded a project that included settings different from the ones
- you were using. Selecting "Restore" a second time will undo the
- effect of the first selection.
-
-
- ZOOM ON SELECTED
-
- There is a new menu item in the Window menu, "Zoom On Selected". This
- feature allows you to directly zoom on a particular feature of one of
- the images: select a set of vertices of the mesh that cover the
- important feature and then select this menu item -- the preview of the
- window that was active will be resized and moved accordingly.
-
-
- ZOOM GADGETS
-
- Besides the functionality described in the manual, the Zoom gadgets
- can now be used in conjunction with the keyboard to execute different
- functions:
-
- Shift + Zoom In = zoom in by a smaller step
- Shift + Zoom Out = zoom out by a smaller step
- Alt + Zoom In = same as the menu item "Window/Zoom On Selected"
- Alt + Zoom Out = same as the menu item "Window/Fit Image"
-
-
- SCALEIMAGE
-
- The SCALEIMAGE ARexx command currently outputs only 24-bit images,
- regardless of the type of the input.
-
-
- TOOLTYPES
-
- Visionaire accepts three more Workbench TOOLTYPES besides those
- mentioned in the manual (Questions & Answers):
-
- SCREEN=name
- Sets the name of the Public Screen that Visionaire opens.
-
- PORT=name
- Sets the name of the ARexx port opened by Visionaire.
-
- NOAREXX
- Add this tooltype if you do not have ARexx installed in your Amiga,
- and you don't want to be informed about that every time you run
- Visionaire. Note that if ARexx is not installed, you won't be able
- to use some of Visionaire's features.
-
-
- SHOWIMAGE.VIRX AND SHOWANIM.VIRX
-
- The information in the manual concerning the customization of the
- ShowImage.virx and ShowAnim.virx files has changed. ShowImage now
- receives as arguments the name of the file (a string) and the format
- of the image (an integer). The format can be one of:
-
- 0 - for HAM images
- 1 - for interlaced HAM images
- 2 - for 12-bit ILBM images
- 3 - for 24-bit ILBM images
- 4 - for 24-bit Sun rasterfiles
- 5 - for 8-bit Sun rasterfiles
- 6 - for 8-bit ILBM images
- 7 - for HAM8 images
- 8 - for interlaced HAM images
-
- ShowAnim.virx now receives as parameters either the format (coded as
- above) and the name of an ANIM file, or the format followed by the
- keyword "SCRIPT" and the name of a script (the script format is still
- the same as described in the manual).
-
-
- FIXASPECT
-
- Visionaire uses an aspect ratio information, included in every ILBM
- file, when scaling the previews. This allows Visionaire to always
- show you a "correct" preview: it corrects the image so that it
- doesn't look stretched or squashed, regardless of the display mode you
- are using. However, many programs generate incorrect or too
- simplified aspect ratio information, and in these cases Visionaire
- will generate a somewhat squeezed preview.
-
- A simple program, called FixAspect, has been included on the main disk
- to address this problem. It must be used from the CLI or the Shell,
- and it allows you to change the aspect ratio information of any IFF
- ILBM image. Type "FixASpect ?" at the shell prompt for an usual
- AmigaDOS help template, or type an additional "?" at the template
- prompt for additional help. The program can be found in the C
- directory of the Visionaire: disk.

- Corrections to the Manual
- -------------------------
-
- Page 56: At the the last paragraph, it should read:
- "The other meshes will be automatically created, and will be
- very close to what you would have done by hand."
-
- Page 69: At the first paragraph, it should read:
- "The selected points are scaled as if their center was fixed
- to the image."
-
- Page 168: The answer to the second question should have added:
- "Note that the mesh shown in the previews is always represented
- by straight lines, regardless of the smoothing settings --
- smoothing affects just the output images."
