#*.IFF files – TPaint
21 messages in this thread
I need to use graphics created on a PC on my Toaster. I tried a test and it
did not work. Here are the steps I used. Maybe somebody can help me identify
my error.
1. Convert 256-color GIF graphic to IFF. (I used a new shareware program
called JASC MEDIA CENTER. I also have but did not try Hijaak 2. Both
programs are on my PC.)
2. Put IFF file on a low density disk and put disk in my Amiga.
3. Use CrossDos to read disk. Icon shows disk name.
4. Start Toaster. Start Toaster Paint.
5. Open File with LOAD RGB.
The file loads but is very very distorted. Is the root of my problem that the
orginal was only 256 colors?
I look forward to any assistance that the members of this forum can provide.
Wes
Wes, do you have AD Pro? If so take the iff in there to convert or save it out
from the pc as a tiff or gif and convert it in AD Pro. I have done this
numerous times with no problems. Also you might want to rescale it to video
dimensions.

No I don't have AdPro or any other image processing program. Any
recomendations?
Wes
PMFJI, I suggest taking a look at Imagemaster R/T while not as EASY to use
as ADPRo it is CONSIDERABLY more powerful and Also ALOT less expensive at
a measly $69.95 or so. includes lots of neato special FX operations and
MORPHING
talk to Ben Williams in the Black Belt Systems forum. BTW I own BOTH ADPro
and Imagemaster, ADPro is great for quick image conversions, Imagemaster
is better for image manipulations and such IMO

Wes I agree with Peter on those points also.

Thank ye kind sir

TPaint doesn't load 256 color iff images at this time. Please convert it to a
24 bit RGB it should load then.
Wesley,
I have just started doing what you are attempting. We've been at it for about a
month. Sometimes files came in fine and other times I had the distortion
problem.
Then last week a light bulb went on above my head. What should the size of the
file in TPaint be. So, I pulled several framestore files into AD Pro. They all
measured 752 x 480.
A few people on this borad also have told me that there is a difference in
pixel shape between the Amiga and the PC. I forget which is which, but going
from the PC to the Amiga I have to set the horizontal scale to 115% and going
the other way I set the scale to 85%. My notes on this are at the office and I
may have reversed them so, let me double check.
Thirdly, the people at HiJack told me that they have a problem with there
program and IFF files. They suggested that I use some other kind of file like
PCX and then at the Amiga side convert it to IFF. So, I convert a file on the
PC to PCX, the bring it into AD Pro. In AD Pro, I convert it to either a
Framestore or IFF file.
TPaint will read the IFF file, whereas, the Toaster Switcher requrires the
Framestore version.
Since I have been setting the correct pixel size (752 x 480) all files have
come into the Amiga without any distortion. I only recently had a problem with
a file that would not show up on TPaint, but did on the Toaster Switcher. You
can read my question that I posted earlier this evening.

Fred,
Its actually closer to 117% and 85.5%. A nit, but if you have a gridded
mech drawing it could make a difference.

Wayne,
Thanks for the exact numbers. The 115 and 85 came from AD PRO.
Fred
Fred,
I futzed with a grid and some "exact" geometric shapes to come up with
those numbers. I'd still like to see published somewhere EXACTLY what the
Amiga/Toaster D2 pixel aspect is.

Wes,
You may have 2 problems: color density and size. The ToasterPaint doesn't
like anything less than 24 bit color. (Try loading a gray scale image to
see what I mean). Also, if you are not 752 x 480 it can be a problem,
especially if it is larger in the x dimension. But of these two, the
color depth is the most important, I think.
In HiJaak, check if it has an IFF24 available that will allow you to save
it out as a 24 bit IFF. If you have the older HiJaak it may only allow 4
or 8 bit color.
The easiest would be to take the file off the PC as TIFF, then laod into
ADPro, scale so that x:y pixel aspect is 1:1.17 then save as IFF 24 bit.
ToasterPaint will load it no problem then.

How old is Hijaak 2? I checked in the program and there is no reference to IFF
24 bit. I think I may give in and get an image processer for the Amiga.
Wes
Wes,
I'm not a HiJaak expert. I only saw a version of it that was floating
around years ago, and since I've seen ads for it. Based on what has
subsequently been posted here, it sounds like HiJaak may not support
IFF24. I don't think you'll regret an investment in ImageFX or ADPro (or
both!).

The image needs to be 24-bit RGB. ToasterPaint doesn't yet support 8 bit
images directly. If you have trouble converting to 24-bit you can load
the 256 color image into LightWave, use it as a BG Image, and render a
medium res frame (antialias if necessary). With the image now displayed
on DV1, go into ToasterPaint and select "Grab from DV1", in a few seconds,
the image will be loaded into Tpaint and you can go from there.
Of course, the simplest route requires you to have Art Department Pro,
ImageFX, or ImageMaster on your Amiga system.

Thanks
I will try this in the short term. Obviously I can't wait for lightwave to
render every image I need to use ( over 100 for this project ). I guess it is
time to give in and get the image processer.
Am recomendations?
Wes
Re: Image Processors. We use all 3 of the 'major' packages, ADPro,
ImageFX, and ImageMaster. The all have strengths and weaknessess, so it's
tough to judge a clear winner…sorry.

I frequently do what tried. I do try to use 256 colors but I don't know if
that's where your problems lie. I've found that using TIFF files produces much
better results than GIFs-don't know why.
Be aware that you also have to resize the image so that it has the correct
aspect ratio for TV.
I use Paint Shop Pro (Windows) or Image Alchemy (DOS) to handle my image
manipulation on the PC side. Both are shareware available on CIS. ADPro
handles those chores on the Amiga side.
I've also found that if you're doing this a lot, it makes sense to set up a
null modem connection between the two machines. That way you're not limited on
file size, and depending on the protocol you use, you can send batches of files
at the same time. I use ProComm on the PC, and BackTalk (a freeware program
available on CIS) for this task.
I know I'm a little off the point, but I hope this helps -dk

Thanks for the info. I have a couple of questions……
1. Where is Paint Shop Pro? It is made by the same source as JASC Media
Center but it is not in the same library.
2. Tell me more about the null modem idea. I have ProComm Plus on my PC. I
do not have a modem on my Amiga, but if I remember correctly I should not need
one. Right? Tell me how you do it – Cables, software, etc.
Thanks,
Wes
>Where is Paint Shop Pro?
It's been a while since I downloaded it, but you can use the IBM File Finder
(go IBMFF) to find PSP.ZIP. Registration costs in the $60-$70 range I think,
but it's well worth it. I'm not sure if the unregistered version is "crippled"
in any way.
>Tell me more about the null modem idea.
You're right, you don't need a modem to do a null modem transfer. Appendix F
of the ProComm (DOS) manual gives the pin-out for making a null modem cable but
you can buy a cable or adapter at Radio Shack.
You'll need a communications program for the Amiga. I found BackTalk in the
AmigaUser forum's communications section. It's _free_ and does a nice job.
It's only limitation is that it only goes up to speeds of 38,400 bps but unless
you have a 16550 UART chip on your PCs serial port you won't want to go faster
anyway.
Once connected just configure the software for the appropriate ports and you're
all set. I use z-modem protocol at 38,400 and it works great-you will see some
errors going that fast, but since the protocol corrects them it's not a
problem.
If you have any further questions once you have the cable and software in
place, feel free to e-mail me here or dkruse@pipeline.com
As others have said, Toasterpaint doesn't handle 256-color IFFs. (The files
are probably valid, it's just a limitation of ToasterPaint and LW. LW loads
256-color IFF but assumes they are all grayscale.) You probably want to use
the ReadPICT program, see the Pict.Readme text file in your Toaster directory.
It explains how to use it.
