• Effects of the use of EF lens and a EF-S camera crop factor calculations.

  I've been reading about sensors APS - C and the differences between EF and EF-S objectives.

  I have two questions pending about how the EF-S-objectives are marketed.

  (1) objectives EF - S need to have the factor of 1.6 x applied for effective focal length or are they marked correctly since they can only be used in APS - C cameras?

  FOR EXAMPLE my 17-40mm 4 L EF lens is actually a 27, 2-64mm when used in a camera to mount EF-S due to the 1.6 x factor.

  So a first objective 60 mm EF-S would in fact be similar to a 60mm EF lens first in terms of focal length and 'zoom' level of the image? Or she also apply the crop factor and actually be a focal length of 96mm?

  (2) are there other attributes of a lens EF you must apply a conversion when using in an EF-S mount? Side f-stop?

  Thank you in advance for any guidance that offer you!

  Designation is fashoned it was for 35 mm cameras and the crop factor is not considered in appointing focal length / range of lenses if they have an EF or EF-S mount. a 60 mm is a 60 mm.

• Document of the crop to the size of a text layer

  My document contains a textlayer. I have to crop the document to match the width of the text. I don't find a way to extract the width of the text.

  In the documentation, I see that TextItem has a width property, but which is available for the text that encapsulates it.

  Is there a way to get the width of the text?

  Read-write. The width of the bounding box for
  the text of the paragraph.
  Only valid when type = TextType.PARAGRAPHTEXT

  This should crop the text.

  NB the text layer must be selected.

  var doc= activeDocument;
  var LB = doc.activeLayer.bounds;
  //This will crop to text size
  //doc.crop(activeDocument.activeLayer.bounds);
  activeDocument.crop([LB[0],0,LB[2],doc.height.value]);
  

• calculate the field of vision or the focal length of harvest

  Is there a way to do this or a plugin that someone knows?

  (If you have a shot at a 14mm but you crop to the center of it, it would be good to know what is equal to the equivalent focal length of culture)

  Set the Info Overlay to show the new cropped dimensions. In the case the simplest where the aspect ratio of the culture is the same original image, divide one side original by the culture to get the crop factor. If the original is from a full camera frame, the equivalent of 35 mm. long focal length times the crop factor. If the camera has a sensor that is less than 24 x 36 mm, the total of crop factor is crop factor of the camera times the factor of culture "in LR. So, if you have a Canon 7 d, which has a sensor 5184 x 3456 pixels and a factor of 1.6 harvest and crop you the image to 2592 x 1728, the crop factor resulting is 3.2 and your 14 mm lens. will take the field of VISION of a 44.8 mm lens. on a 35 mm camera.. If the harvest of LR has an aspect ratio different that the original, the equivalence is, of course, different for the height and width.

• Satellite U405 - S2833 Fingerprint error: could not open the sensor

  Hello, I am very new to the forums so I apologize in advance if I don't give all the necessary accurate information in this thread.

  I have a Toshiba U405-S2833 and it came with the TrueSuite Access Fingerprint Software.

  I downloaded an update a few days ago, but I don't remember if it's for Vista or Toshiba. Since then, my fingerprints were all removed from the system, and when I try re - save, I get this error message "error: could not open the sensor" I can't find the material to fix the sensor manually without going through the TrueSuite software.

  Any help would be greatly appreciated.
  Thanks in advance

  I am also having the same problem.

  My boss uses a Satellite U405-2628 fingerprinting and with the sensor TrueSuite Access Manager. It worked fine, then I updated windows and it has stopped working. I was on the updates and noticed an update of TrueSuite and thought that maybe that was messed up things.

  Then there were other issues that went past me locked out of the machine (anti-virus and loss of relationship with the field... also my fault). So I decided to wipe the machine and install fresh Vista.

  I installed everything but the TrueSuite software still not able to open the sensor. After hitting my head on it, I decided enough was enough and I restored it using Toshiba recovery disks.

  It took a few hours and here I am logged in as administrator and the TrueSuite software still cannot open the sensor. I don't know what I can do, since it is to return to the factory settings.

  As the above poster said, HELP!

  Thank you.

  ... a little later...

  Well, I managed to do work, and this can be useful for some people out there since I found no easy answers. I can't guarantee anything, and it's really complicated... so here go us.

  First, I downloaded the latest update from Toshiba (util_fingerprint_27460A.exe) and nothing has worked.
  Then I uninstalled the sensor since (click right, uninstalled) Device Manager to uninstall the driver as well (it should invite you to do so)
  Then, still in the Device Manager, I scanned for new hardware and it came with my sensor. I said to look for drivers and when he could not find, I think it gave me an option for windows search for an answer... or something like that. He came back with a link to Authentec (www.authentec.com/win7update/w7wbf32.exe, I think). So I downloaded that and installed. He rose through the device under "Biometric devices" then before... I think it's under the "Personall security device" or something like that. But alas, still no luck. So I uninstalled all the device from the Device Manager (taking care of uninstalling the driver as well) and of the TrueSuite software. Then came the break I was looking for.

  Online research I came across this page... http://members.driverguide.com/driver/detail.php?action=download&driverid=1194755. I had the chance before to DriverGuide.com so I thought what the heck. It is a driver of HP for the same sensor and it is dated 2006. So I downloaded and installed. Still nothing...

  Disgusted, I thought, well let's try to install util_fingerprint_27460A.exe on top of that. So I did, restarted and I couldn't believe my eyes when he said to connect and register fingerprints not seriously. And so I did. I hope this helps people, I don't really know how the sensor I so messed up, but I'm glad it worked.

  Yet one thing... and this may be important. When I took TrueSuite first after doing all this, he told me that the storage of fingerprints was full... or something in that sense. So I clicked the button remove all traces of fingers button and it I would like to register my fingerprints. I'm starting to wonder if that was all I had to do in the first place... Guess I'll never know.

  Good luck.

• astrophotography. I want to know that the focal length is to determine the field of vision?

  I'm interested in astrophotography.  I want to buy a camera for my telescope.  You can find the field of vision, if you know the focal length of the telescope.  But what is the focal length of a camera with a fixed lens?  If I have a 50 mm lens, is the focal distance 50 mm? or do you need to know the distance from the camera of body image sensor and add it to the lens focal length?  Thanks in advance...

  If you have a 50mm... lens focal length.  The focal length is the distance between the end of the lens and the image plane.  If you look at a digital SLR, there is a symbol on the body (usually the top of the body and often near the viewfinder) that looks like a small circle with a line through IT... which line marks the position of the focal plane inside the camera.

  There is a friction more... If you have a 'simple' goal, it would be the focal length.  Many modern lenses are technically able to be physically shorter than the focal length they provide... because of the types of 'glass' and the configuration of optics.  So the focal length is based on how long a simple goal should be to provide that same value (even if you were to physically measure it and not get this value.)

  All telescopes list their focal lengths, but also among the specs of the telescope focal reports.  I have a refractor of 540mm with an opening of 101mm... so it is 'roughly' f/5.4 scope.  I have also a larger 14 "SCT with a focal length of 3556mm and it is a stretch of f/10.

  The distance "flange to focal plane" on a camera Canon is 44 mm... in the grand scheme of things with a telescope, it will not substantially change the focal length of the image.

  Depending on the scope, you can use either a "focal reducer" or a "barlow" to decrease or increase the focal length.

  One last thing... many designs of 'Newtonian' type telescope is problematic for astrophotography.  This is because most of the glasses and catadioptric telescopes are designed with the intention that a person would use a diagonal of 90º with their eyepiece.  "The diagonal has a tendency to add"roughly"2" to the overal of the focal path length.  If you are using a camera you take this "diagonal" and simply attach the camera for a shot "straight through".  So even if you have lost the focal length 2 ", created by the diagonal... the camera adds"roughly"the same amount of back in.

  BUT... When you use a Newtonian telescope of reflector design, the eyepiece is near the front and there is no "diagonal" in use.  This means that when you add a camera, focal length gets longer, it would be with an eyepiece.    Pull door-eyepiece tube has some development trips... but because the camera is the longest focal length, you end up having to run the focuser completely 'in' to shorten the length of the focal length to put the image in focus.  And that's where you are having problems... very often on a Newtonian telescope, you exceed the limit of traction of focuser (you can't shorten the development any more that you have) and the image was just starting to focus... but it's still pretty fuzzy.

  This problem not to poison all the reflectors of knighting... some can accommodate cameras and still come to focus.  You really check the specific scope.

• Question regarding setExtent and getPreferredWidth for the custom field

  I am trying to understand the difference between getPreferredWidth and setExtent, which relate to the width of a custom field.

  I create a field that may be greater than the width of the screen. The field is made up of cells (for example columns and lines or cells, such as a table). The cells contain text, shapes, lines, color, etc. When I display the field I only paint the visible columns on the screen and allow the user to use the trackball to accomplish the columns out of the screen.

  At present, getPreferredWidth returns the total width of the field without all the empty columns, is longer than the width of the screen. I use the same value in setExtent for width. GetPreferredWidth must return the size of the field that is painted on the screen - the total width less the width of the columns out of the screen? I have the same question about setExtent - width either in total, longer than the screen width or the width of the part of the field that is painted on the screen?

  If I use the width of what is painted on the screen or the other of these methods, then the width changes when the user scrolls through the field. As the user scrolls, I calculate the number of columns will agree to a width of the screen and paint these columns. Is it a problem to have the PreferredWidth and the setExtent change width? I read that setExtent is called only when the Manager sets this field, so that the changes will not be recognized.

  It seems to work in two ways in a few simple tests, but I was just curious as the value of width that is right.

  Thank you!

  Mark

  When a field has changed in a way that requires the update of the screen (for example, after scrolling offset changes), simply call invalidate() from this area. That will eventually lead to paint (Graphics) for the field. At this point, you return the update field. (If only part of a field - as a single cell - needs to be updated, there invalidate() versions that accept arguments where, for efficiency, you can limit the update for just this part.)

  If I understand your needs, you can achieve the effect desired in the paint method. You can use the current dimensions of the field, the cutting of the graphics area, and your internal roll compensates to decide what to paint and what to delete. Let your custom field leave white space where you decide of doesn't make is not part of a cell. There is no need to change the scope of the field.

  If you go about it by changing the dimensions of the field, and then you ask the system to play much more work he has to do. If the custom field is the only field on the screen, it won't make much difference in the behavior (although there may be performance). With more than one field, it can be weird effects. For example, suppose that your custom field is one of several fields in a HorizontalFieldManager and you change the field width. When the HorizontalFieldManager recalculates its own layout, it will change the horizontal position of the fields to the right. The effect on the user, I think, would be really confusing: as the custom field parade, parties to the right of the screen could bounce left and right as the changed width field. I can't imagine that's what you want.

  Here's another way to think about this: absent some bit of style, your custom field would prefer be exactly wide and high enough to show all without scrolling. So the width and height would be based on adding the appropriate cell widths and heights, regardless of what actually is on the display. (It's also a long time that you do not have something fanciful.) If the optimum height is a function of the width available - as with sheathed on the line of text - you would implement this logic in the layout method. You then have no use for autonomous preferred width and height).

• How to align the Hcenter fields in VFM?

  How to align the Hcenter fields in VFM? its giving problem

  solution on mine! years of posting for reference...

  what I did earlier.

  I wanted to have a manager of fixed size (maximum size) and put fields here, during an aliging then using stylebit it did not work. I used sublayout and fixed to what extent a perticular dimension

  resovled doing problem.

  It is not sufficient (or necessary) to if you want to use sublayout to have a fixed size, if you use the alignment, bcz setting hardcodedly properties, the other model overridden, so u must override the methods 'getPrefferedWidth & height', not the two held all the time, but according to the needs, if you want to:-alignment, you can try only method "width" and comparable to V-alignment. I included these methods and found that half of my UI related issues would have resolved more easily, if I tried this previously.

• FlowFieldManager not 'compatible' with the text fields?

  Hi all.

  I'm making an icon to follow the end of a given text. A bit like the phoneLog done with the green phone icon next any number that you enter.

  I tried the substitution of the DrawText, but unfortunately after conditioning to the new line I don't have an X coordinated to begin to draw.

  That's what I would like to:

  +-----------++-----+

  | text 1234 | icon |

  +-----------++-----+

  After entering the text more:

  +--------------------++-----+

  | text 1234567890 | icon |

  +--------------------++-----+

  Unfortunately FlowFieldManager encapsulates the new line icon

  It seems that she's done this before and after each text field. If I have two icons, one after the other, they have a format horizontal, but at the moment where I have to add a textField, it is wrapped in a new line (are complemented by the icons) or icons are pushed to the next line (if the text box before the icons).

  So, how can I add this icon to track the length of the text?

  The problem here is that text fields normally tell their manager encompassing that they want to take the entire width.  FlowFieldManager who will respect and give them the entire width.

  You will need to customize the text field, replace the functions of layout and width and make sure he asks only the size that he actually need.

  If the text cannot be updated, and then you try to use rather than RichTextField LabelField.  LabelField asks only the width he needed.

  Sorry I can't give you any appropriate code because I have never done this.  I did not because from a user interface point of view I don't think it looks good.

  This mechanism can fail when the text field resumed more size on a width - fields are always "rectangular".
