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. jmb

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 Member of the Association of Media Professionals

Wes I agree with Peter on those points also. jmb

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

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

Wayne, Thanks for the exact numbers. The 115 and 85 came from AD PRO. Fred
#92506From: Wayne ColeOct 12, 1994 3:31 PM
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. wmc – via Autopilot!
#92340From: Wayne ColeOct 11, 1994 7:09 AM
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. wmc – via Autopilot!

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
#92503From: Wayne ColeOct 12, 1994 3:31 PM
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!). wmc – via Autopilot!
#92348From: Trent K. JohnsonOct 11, 1994 7:48 AM
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. Trent/ReAnimators
#92368From: Wesley HelmsOct 11, 1994 12:23 PM
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. Trent/ReAnimators

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
#92367From: Wesley HelmsOct 11, 1994 12:20 PM
Duncan 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.
