Erik (sorry about the name screwup… ;^( ),
I didn't "neglect to mention it" ("it" being area selction
inaccuracy), I wasn't aware of it as a problem. Further, if it used
to be a problem it likely isn't now because the area selection code
has all been rewritten for the next release. :^) I have *never* had
an area selection problem such as you describe; of course, I work in
magnify because when an image is scaled down, you can't always see
the precise boundries you want to work with. You must remember that
IM R/t always scales the display to match the aspect and overscan and
etc, so many images cannot be pixel-for-pixel edited without some
level of zoom – this is inherent. Regarding autoscroll… I _hate_
that and that's why it's not there. I prefer to combine the selected
areas – you have much more precise control and you don't pay the time
penalty for redraws every time you get too close to an edge without
thinking. I suppose we should add it with a user option switch (so I
could turn it off). I'll make a note of it.
Since a large number of our customers ARE producing FLC's that work,
it seems to me that your FLC player may not be up to the task of
dealing with the FLC you are generating. Some FLC players are limited
to specific resolutions or ranges of resolutions. This may be the
root of your problem – or there may be a bug that specifically
affects the way you are doing things as compared to others' methods.
Tech Support is not at liberty to divulge release dates for new
versions unless I *specifically* say so, and I have not, nor will I
at this time. Don't blame them, blame me. :^)
Our "little boolean operators" do exactly what you describe. Press
the appropriate one (just like you'd press the "little shift key" in
PS) and use the make mask operation under process and it'll do just
what you describe (with any set of area selection tools)… add or
remove areas. once you've got the complete area done, using redo and
any operation gets it done.
The use of "actual" images of the brush are a bit problematical as
well, due to the huge number of display modes it'd have to be
supported in. Not impossible, just really, really, hard. We'll
probably add it sometime when we've got several weeks to spend on
that one issue. Since what's there works just fine, it's not a high
priority.
You can't "XOR a B&W zebra stripe", Erik. When you XOR, you get
colors which are ordinal opposites of the palette number of the pixel
under the XOR. You have to _draw_ a zebra stripe. When you draw one,
you have to redraw the image data underneath it. When you redraw in
the case of a low color image, you have to know either (a) the exact
display state for every surrounding pixel to reconstruct the dither
or, (b) save every pixel, or (c) redraw without dither (which
seriously degrades the image and takes mucho time). When you XOR a
line, XOR'ing it again removes it quickly and easily and without
resorting to the image data or dither issues. Those are very time
consuming (in the CPU sense) and that's the precise reason that the
functionality isn't there. It's easy for an end user such as yourself
to forget the color limitations that stock Amigas impose on software;
when you're picking colors for image fidelty from a group of 16, for
instance, any two colors dedicated to "zebras" significantly (as in
oviously) degrade the display image quality – this is something we
like to avoid as much as possible.
Heck, it we had just 256 color and 24-bit to deal with seriously it'd
be a whole different ball game. But that's not the case with the
Amiga. Or even the PC, anymore.
The co-ordinates problem sounds like it would be easily fixed, and
should be. I'll see to it.
Imagemaster R/t can "erase" to a previous version of an image easily.
Load it into a buffer. Keep it around as you work (in fact, make the
buffer each time you decide you have a "keeper" version. When you
want to go back, select it as secondary and rub it thru. Works just
fine.
Photoshop: Imagemaster R/t is not a Photoshop clone. Photoshop is
fine, for what it does (which is a darned sight less than IM R/t can
do). It's got some very convenient tools and shortcuts; and for
"prepress" ops, it's pretty much without peer at this time. However,
IM R/t is designed to be a generalized image manipulator – and it far
outperforms Photoshop at that task. I'm NOT saying we shouldn't use
some of the capabilities that Photoshop has – sure, they'd be very
convenient. But in point of fact, I could list you literally hundreds
of operations you just can't do in Photoshop at all which IM R/t does
without breaking a sweat.
On Production actually got the credit right, eh? Amazing. After the
all the botch-ups in that other recent review (new media, was that
it?) where they screwed up darn near everything, it's nice to hear
that some accuracy snuck in somewhere. $599 list price, indeed. Hah!
Thanks for the feedback.
