OK, here's the deal. I used MacAttack II to convert a geoPaint file to Macpaint format, uploaded it to a mainframe with Kermit in binary mode, then used binary FTP to download it to a Mac. When I converted the file with BinHex, BinHex gave me an end of file error,so I extended the file a bit with a word processor. BinHex read it OK but the resulting file was slightly scrambled: it had all the data was there, but sections of the picture were shifted right and left. Can anyone tell me if this sounds like a problem with the transfer, or with MacAttack? Has anyone used MacAttack successfully to move geoPaint files to the Mac? - ----------------------------------------------------------------------- | | | | Aaron Peromsik | "Please insert disk with | | hh2x@cornella.cit.cornell.edu | with the 128 deskTop v2.0" | | hh2x@vax5.cit.cornell.edu | | | | | -----------------------------------------------------------------------

I have never sent MacPaint pictures to a Mac, but I have sent them to other computers, and MacAttack has worked great so far. Be sure to watch the options that you are using when you convert to MacPaint format, such as: MacBinary header on/off - This option lets you add or leave out the binary header used by the Mac. I leave it off, but you may need it to be there for what you're doing. GeoPaint pictures are 640 pixels wide, while MacPaint pictures are 576 pixels wide, so a full 64 pixels must be chopped off of the picture to make it fit into MacPaint format. MacAttack lets you choose what part of the picture you want to lose, through the "starting column" option. You can choose a number from 0 to 8, and each number chops off 8 more pixels, starting from the left. For instance, column 0 will take the left side of the image, and leave off the right 64 pixels. Column 8 will chop off the leftmost 64 pixels and leave the right side. Columns 1-7 will take the middle of the image, with some pixels left out on both sides. Also note that using Kermit is dangerous with binary files. Most Kermits expect to transfer text, since that's what Kermit does best, so you must be absolutely sure that ALL of the Kermits you transfer to understand that a binary file is being sent, and no translation should be done on any characters. -- David DeSimone, aka "Fuzzy Fox" on some networks. /!/!
