    Default Errors On TIFF Export

    I have encountered these errors on occasion in the past, but I am currently working on a photo restoration project, and it's becoming a real nuisance.

    Does Xtreme Pro 4 have a limit on image size for TIFF export?

    For example, if I import a TIFF image (these are scans at 600dpi), it shows in Xtreme as around 1000x700ppi (at 96dpi). I then colour correct and try to export a TIFF image (at 600dpi, around 6000dpix4000dpi), I get the first error in the attached gif file. So I tried reducing the export size to 550dpi, and then I got the the second error. I finally reduced the export size to 500dpi, and it exported.

    Anyone know what the issue is?

    I should add that I am exporting at 24 bits per pixel with no compression.

    I'm not sure about the size limitation though there should be a reference to this in the Help file.

    But more to the point, do you know the actual size of the image in pixels, not the resolution, but the physical size? For example, a 10" x 8" image at 300dpi is 3000 x 2400 pixels. Now if I want the image to be the same size after I edit it, then the export size should be 3000 x 2400 pixels.

    Hi Gary,

    Thanks for the reply.

    Maybe I am missing your point, but when I open a 3000 x 2400 pixel tiff image (5"x4" photograph which was scanned at 600 dpi) in Xara, it appears in the Xara window at 480 x 384 pixels (96dpi...ppi).

    When I am done working on it, I export as tiff, and the defaults are:
    Width: 480 Height: 384
    dpi: 96

    So I change the 96 to 600 dpi, and that automatically adjusts the Width back to 3000, and height to 2400.

    I could change the 480 to 3000, which would automatically adjust the 96 to 600dpi. But I know all the images are 600dpi, so my work flow is easier in this case as I don't have to reference the original image pixel dimensions.

    But I am still getting these errors on a regular basis. If I close Xara and re-start, then the exports work for a few images (including the last one to cause trouble) and then the errors start again. It's as if there's a memory leak, and after a few large images are loaded and exported, the program can't handle any more.

    If someone would be willing to try a test of this process and give feedback on their success, I would be greatly appreciative.

    Cheers,
    James

    James, Xara has problems not just with high res TIF export but also high res PDF export. Xara is not and never has been a raster specialist application. You can either be a jack of all trades or a master of one. Xara has mastered the vector trade handsomely. It should have stuck to that if it was aiming at the professional design market. But it's not. It's aiming at the everybody market (something Adobe do not do with Photoshop or Illustrator). In my opinion and in my experience it comes a poor second to Photoshop for high resolution bitmap handling, including export.

    Frank,
    I appreciate your view, but would you be willing to test this scenario out on your setup and see if you get an error? I don't want to point the finger at Xara in case it is specific to my system.

    How much memory does Xara require, recommend?

    I would, but it's 02h30 here and I am just going to bed. I'll try tomorrow if nobody else has helped you by then.

    had a 3444pix by 4272pix 600dpi tiff [M and D 14] to hand so gave it a test [blanked the thumbnail as I can't post the image]

    this will export at the same size - but not if I double the size in xtreme pro 4, make a 600dpi bitmap copy, and try to export that at 600dpi [it just gets stuck and does nothing]

    it does work in xtreme 2

    changes to the way things work in xtreme 4 [and maybe 3]are responsible for this as far as I know - perhaps reflected in the way the bitmap gallery reports the original file [see attached]

    this has come up before but I cannot find the threads at present..

    PS I'd left the xxp4 hung export running and when I went back to close it there was the message:

    Honestly thought I was going to be able to help, but I exported the image 4 times on different settings, each time at 600dpi and 2650 x 3219 pix and every time it exported in about a second without any problem.

    reckon yours worked Frank because your image is smaller

    the image that I exported [200% of the original] was 6888pix by 8554pix at 600dpi [no compression]
