#URGENT BMP Saver problem

I have been attempting to save a bitmap IFF file as either a BMP or PCX file in ADPro so that I can use the file as a template in Adobe Illustrator on my IBM PC Windows machine. However, the file, no matter how I save it, seems to be unusable by the Adobe software. I believe I need to import a 1-bit image (the bitmap is a black and white, 2/C hand-drawn logo typeface), but when I try to save the file in ADPro, it automatically saves it as a 256-color image, which can't be used as a template. When I convert the BMP 256-color image to 2-color and then try to save it again as a 1-bit file, the program does seem to save the image. However, when I attempt to reload the file, all I get is a garbled image consisting of a bunch of diagonal lines. Trying to save the image as a PCX format image produced even stranger results. I then attempted to try to save the 2-color bitmap as an encapsulated postscript file, thinking I could just import it into my document and work around it. However, the program said that the EPS file I saved was garbled, and the "offending" character was " ' ". I had hoped that by using ADPro, I would be able to do my scanning on the Amiga using my ES-300C, and not have to purchase PhotoShop for my IBM. However, if the images are garbled when being saved by ADPro, there may be no other choice. Is there any way to save a bitmap in ADPro as a 1-bit BMP image so that I can import it as a template? Any insights would be most appreciated. PS: I have ordered the ADPro 2.5 upgrade, but I am working on a freelance newsletter which has to be out this week, so I don't think that the upgrade, if it would solve this problem, will come in time.

We have used BMP files of various types created by ADPro in Adobe Photoshop on the Mac and have experienced no problems. Same goes for EPS. We have also tested w/ Quark Express, Adobe Premiere, Aldus Freehand, Infini-D and Strata Vision as well as Microsoft Word for Windows, Harvard Graphics, Windows Draw, Corel Draw and Image Alchemy. I will attempt to duplicate your problem but I seriously doubt that it is a problem with ADPro or any of its modules.

The problem I'm experiencing is really not with the BMP saver per se. I have been successfully scanning and saving files through ADPro and porting them over to Quark Express on my PC, as long as they are 8 bit files. They look fine on a page. My only question in that regard is that they seem to be porting over very small, even though I've scanned in a large image, I have to blow up the image by over 800% to get it to fit a window just 1" x 1" in size. However, it still manages to print okay, even though this seems like a ridiculously large increase over how the original image was scanned and saved. Like I said, I'm not having problems saving the BMP 8-bit file and porting it over, only getting a BMP file to come up in Adobe Illustrator as a template. Evidently, Illustrator will only accept 1-bit images as templates, not 8-bit images, but when I try to save a 1-bit BMP file, that's when I get the garbled file. Even though ADPro seems to be saving the 1-bit file, it turns into garbage, even when I retry to load it back on my Amiga screen before trying to port it over. I noticed that in your message you tried a number of different software packages, but Illustrator was not among them. Could you possibly try to duplicate this sequence and let me know how I should save the BMP file so that it will port over as a pure b/w BMP image (not grey scale). I don't have the Pro Pack, so I was unable to try to save the image as a TIFF file. Would saving the file this way work out any better? Without the Pro Pack, I can't test it for myself, but if it doesn't work, there's really nothing else in the Pro Pack that I need at this time (although later, maybe). Thanks for looking into this. I appreciate your help.

It sounds like the program you are using is reading the DPI resolution of the image and using that (ADPro defualts to saving images at 300 DPI). Try using the Def_Pxl_Aspect operator and change the DPI res to 75. The image should look full size in your PC program. Unfortuantely, we do not have a copy of Adobe Illustrator to test with but I can run it through other Adobe software to see if the same thing happens.

Thanks for the suggestion about the size problem. I'll try that and let you know if it works. I wanted to update you on the BMP problem. I had a deadline to meet, so I brought my IBM disk on which I had saved the ADPro-saved BMP 24-bit file which I wanted to use as a template, to work and loaded it up on our Mac Quadra there. The 24-bit BMP file loaded fine into PhotoShop on the Quadra, and I was easily able to convert it first to a grayscale, and then to a 1-bit bitmap BMP file. I brought the same disk home with the 1-bit BMP file saved with PhotoShop, and that loaded just fine on my Adobe Illustrator program as a template. So at least I know that the Illustrator program was not the problem. I was able to do a trace and finish the art (a title headline for a Newsletter). However, I still haven't been able to figure out how to save a 1-bit BMP with ADPro. Was the BMP saver created mainly to save photographs? If so, it works fine, but maybe the developers there didn't consider the use of templates, so maybe they made no provision to save it in this way. The manual is sort of vague in this regard and mentions saving 24-bit and 8-bit BMP files, but not 1-bit (although it's sort of infered from the 'n Color Image' option. And in fact, that's what I had tried to use, and it seemed like ADPro attempted to save the 1-bit file in that way. But like I said before, when I tried to redisplay it, it turned into garbled diagonal lines. I just wanted to let you know that I accomplished the task with PhotoShop (and the AdPro original scan), but in a very roundabout way. And I can't always be sure I'll be able to use the Quadras at work whenever I have a freelance job to finish. Now, if I could only somehow get one of your Amigas to duplicate the A4000/ES-300C problem so many of us are having……

Saving 1-bit BMP files is simple. Just render the image as 2-color and save as BMP. Chris Edgin ASDG tech.

Chris, That was the first thing I did before I called you the first time! I rendered it as a 2-color image and saved it under the middle option 'n Color Image' which appeared to actually save the image successfully. However, when I then tried load it back into ADPro, it was garbled…just a collection of horizontal lines. I tried to save the 2-color image as the 1-bit image under the 'Cropped Screen Image' option, and the same thing happened. I obviously couldn't save it under the Bit-Plane Raw Image option, because that saves only 8-bit or 24-bit images. Did you try to load the image back after you saved it? And was it not garbled? I've been working with ADPro for over 4 years, and I consider myself a somewhat experienced user, so your suggestion was, of course, the first thing I had tried…but it didn't work, which is why I contacted you in the first place. Also, did you try to load the image into Illustrator? I hate to keep harping on this, but I followed the obvious proceedure, which you just suggested, but it didn't work! Jeannine

Well, the obvious procedure is really the only procedure. Unfortunately, we do not have Adobe Illustrator to test with, but we have a gaggle of other Adobe software (like PhotoShop and others ) which exhibit no problem. We have tested the files going both ways (to and from ADPro and Photoshop) and have found no problem. We will need to check w/ some of our beta testers and see if they hav Adobe Illustrator for the PC and see if they can duplicate [Ayour pr [CChris Edgin ASDG tech.

I'm sorry that you were unable to find the problem I am having. Actually, you wouldn't need Illustrator to recognize the problem, just trying to call back the 1-bit BMP image would exibit the program in ADPro. Like I had mentioned, if I try to just save a 2-color image with the BMP saver as a 2-color image (rather than an 8-bit image), I get a garbled image when I try to reload it into ADPro. It doesn't only exibit this problem when I load it into Illustrator, but when I try to call up the image anywhere. I've tried saving the BMP under different dither routines, but that doesn't seem to have any effect on the final result. It just appears that my copy of ADPro cannot save a 1-bit BMP image at all. Maybe the same bug (in the program or on the Amiga itself) which causes this problem has something to do with the ES-300C problem as well (just a conjecture, since you don't seem to have either problem at your end). It's very frustrating (for you as well, I assume) to have these type of problems, doing all the right things as described by the software, but not getting the proper results. Maybe the upgrade will somehow fix this problem. I'll test it when I get the 2.5 package and let you know. I was really hoping not to have to rely on PhotoShop for image processing, because I do prefer working on the Amiga rather than on my IBM for my more creative work. Thanks for trying to solve my problem anyway. Jeannine

I will keep banging away at the BMP saver on my end (I hate it when I cant duplicate a problem on this end) and see what I can find. Chris Edgin ASDG tech.
