Rod.
When you rotate a square or a rectangle, opposite sides remain parallel and internal angles retain their 90 degrees value. When you skew a square or a rectangle, opposite sides remain parallel but the angles change their degree-value -- two opposite angles become greater than 90 and the other two opposite angles become less than 90. If a scanned stamp ends up with its base line not parallel to the horizontal axis of your monitor, you straighten it by rotating it the number of degrees it is off-parallel. Paint Shop Pro has an automatic feature for doing just that. A line with two "anchors" is set on the image. You take this line and place it on the border of the design or along the perforation of the stamp and press 'enter'. Voilą, it's straight! Hope this helps. -- Tony Vella, Ottawa, Canada http://tv-stamps.shorturl.com "Sir F. A. Rien" wrote in message ... Rod found these unused words: On Aug 22, 9:17 am, Sir F. A.

I place the stamp on the scanner bedMy humble understanding: When you rotate a square or a rectangle in a position that is very slightly (twisted, slanted, biased or distorted) take your pick, to the alignment register of the machine. First two OK; eh, on 'biased'; last ... you've got to be joking! "Distorted" can't be corrected by rotation as that term implies more than misalignment to an x/y axis. I think that can be considered "skewed" One may 'think' anything ... To then re-align the program "de-skews" Whatever ... misnomer! also see "skewwhiff" askew, awry. Apart from that, it appears to be the accepted nomeclature in image programming. Missed a word, rod ... "accepted nomeclature in [amateur] image programming." Photoshop and other -=professional=- programs make a very great distinction between rotation and skew. Rotation affect the image as a whole, skew 'shifts' a distorted image back into rectangularity. Naturally both tools can be used for effects as well, eg: skewing a box -=out=- of a rectangular shape into a parallelogram. |

Perhaps my opinion is better understood as what JA suggested, the pertinence of the (amateur) reference. If I need to find a scanner, that, for want of a better word "re-aligns" an out of rotation scanned image, then I will need to search with a text string "de skew" for best results. It seems (to me) to be the accepted method of describing the operation I seek, even though as you explained, is not entirely correct. If, however, you suggest the de skew operation does what you describe, then that's not what I need. I need, exactly what the OCR program does prior to reading, aligns the image perpendicular to what it recognises as lines of text or image blocks. (and not the perfed border) Rodney. |

I can't say that it does/does not use the edge of the item (perforations) or the darkest (printed) edge (line) within the item! What is truly frustrating is that Photoshop does such a nasty job of splitting and the rotating individual items. I gave up on it for the Belgian RR project. I use a program called Cropper. This keeps the huge graphic onscreen while you can crop out images and save them. This is backwards from the conventional method of cropping an image, saving it and the re-loading the huge graphic. Saves massive amounts of time. Although time spent well with Cropper is then eventually lost opening it up and finalizing with PhotoShop. |

The adjusting and saving of individual selections is one of the main reasons why I have been using Corel Suite since the very first version. Another reason is that it's a local software - just down the road - and I got CorelDraw Suite 1 for free long time ago. With Corel PhotoPaint you scan a whole page, then either finalize and save the whole page, or finalize and save individual selections (in my case, stamp by stamp) . In either case the main image never needs reloading. One thing that annoys me in Corel PhotoPaint though, is that the image straightening process is still the old-fashioned freehand rotation. I can't understand why Corel does not adopt the auto straightening feature in Paint Shop Pro (also a Corel Co. product) into their CorelDraw Suite. I find that I use Paint Shop Pro just for straightening images; I don't think I have ever used it for anything else. -- Tony Vella, Ottawa, Canada http://tv-stamps.shorturl.com |

Hi Tony,
EzImage has had what you are loking for since 2003. It has Auto-Separate, Auto-Crop & Auto-Rotate. Major auction house, stamp dealers & even the Smothsonian use it for their imaging projects. Imagine taking 50 stamps & scanning them all at one. Then with one click, have EzImage separate, rotate & crop them for you. EzImage was reviewed in Linns by Bill Sharpe. You can get a free demo to try from my site at http://www.ezstamp.com I will be glad to answer any questions regards Marios -- -------------------------------------------------------------------------------------- Developers of EzStamp, AlbumGen, EzGrader & PCVU Email: OR Websites: http://www.ezstamp.com http://www.stamptools.com/ http://www.pcvu.com "Tony Vella" wrote in message ... wrote in message ...

This keeps the huge graphic onscreen while you can crop out images and save them. I'm not suggesting buying a new scanner, :0) but this is what Epson offers.... The preview screen can enable you to place a "carousel" around the image needed to scan. http://cjoint.com/data/izfRMud6en.htm The benefits are the ability to scan differing sized articles whilst preserving a desired resolution. (you cannot do this with an initial scan then cropping) I can scan up to say 40 stamps, with one click or, scan one tiny stamp, adjust the resolution, then scan a very large item. The (lack of) "auto rotate" is the only blight in the Seiko software. Rodney |

Incorrect. Re-read the post. Yes the resolution is maintained. (but this is what we need to avoid) You have two articles, a MS and a German "Noptofer" label. If you have low res to encompass the MS the noptofer label will be blurred. If you have high resolution, the the MS will be a huge capacity scan. You may also wish to take to task "Marios" and his Ezi Image, is it "amateur" ? He refers to rotation as "skew" in his preamble. |

You have two articles, a MS and a German "Noptofer" label. Oops, see, this is what happens when you have a glass of water with brekky, istead of a large black coffee. Should be "Notopfer" label. Apologies to our German friends. |

Rotation & De-skew are the same thing.
regards marios PS: There is nothing amteur about EzImage. I invite you to try it fo yourself . -- -------------------------------------------------------------------------------------- Developers of EzStamp, AlbumGen, EzGrader & PCVU Email: OR Websites: http://www.ezstamp.com http://www.stamptools.com/ http://www.pcvu.com "Rod" wrote in message oups.com...
