Rotate a raster image

[PSI-CAD]

Hi,

I have to turn precisely a raster image, but there is no way to enter a value like when rotating the WCS. Am I missing something ?
Is there a way to decrease the sensibility of the mouse in this case ?
Another problem is the snapping to the original position.

Thanks in advance

You can only rotate images in increments of 90 degrees.

Try going to Edit-> Move Object and then change the Transform Motion to Rotate. This will allow you to specify the vector, point and angle of rotation.
This way you don't have to change the mouse sensitivity.

Sorry, Move Object won't work correctly. It will distort the image! I didn't realize this earlier.

Hi Cowski,

It' not correct. We are not limited to 90°, but the main problem is the "snapping" to the original position. Did you try it ?

Are we talking about a 'Raster Image' on the face of a Drawing? IS so, yes, you are limited to rotating the image by 90° increments. This is because of the way 'Raster Images' are converted into something which can be 'plotted' (yes, we still have to support 'plotters' some of which still use PENS or at least depend on a scanning technology which actually includes things like ink-jets). Since a 'raster' is just that, a 'raster', we use the way the pixals are aligned (a rectangular matrix) to create the inforation which gets 'plotted'.

If you truly need to have a 'rotated' image on your drawing at something other than at 90° increments, you will need to take your original image into some sort of image editing program, like Photoshop (note that even 'MS Paint' will only rotate an image using 90° increments), and rotate it there to what you desire and then place THAT image on your Drawing.

I was working with a raster image in a drawing the other day, so that is what I was referring to. I forgot about the ability to use studio to bring in a raster image into modeling, since I've never had a need for that functionality. I don't know if the studio raster image manipulation has the same limitation.

OK, if we're talking about inserting a 'Raster Image' into a Modeling session, what version of NX are you using? I ask this because with NX 8.5 I have no problem using the drag handles to rotate the image. Now it is true that there's a snap angle associated with moving it a small amount away from its original position but this can be overcome by using Move Object once you've placed the Bounded Plan that the Image has been attached to. Using Move Object you can type-in any incremental angle that you wish.

Note for NX 9.0 the 'Raster Image' function in Modeling has been completely reimplemented and you will now be allowed to use the CSYS drag handles the way you would with any other function, where you can either dynamically drag the image or enter explicit values for X and Y or Angle. We've also removed the restriction of only supporting TIFF images. A 'Raster Image' can now be any of the common image formats, including JPEG, PNG as well as TIFF.

Hi John

I apologize because I forgotten to say that I was talking about 3D Raster Image and I am using NX8.5.2

I don't agree with your suggestion about Move Object because It will distort the image! as said hovelale or only the sheet body is turned (have a look at the attached jpeg file)

OK, I now see what you mean when you're attempting to use 'Move Object'. However, you can still rotate the image by just edting the Raster Image object itself, just that there's no direct way to enter a value for the angle and there is that 'snapping' issue when attempting to move it a very small amount. However, the 'snapping' issue can be mitigated a bit by first rotating it to some other position away from the initial location as long as it's not exactly 90° and then rotating it a second time, back to near where it was originally and you will now be able to position it to where it was only 1 or 2 degress from that initial position. As for knowing the angle that you have moved it, as you're moving the image note that the system will report the angle that you're dragging it in the 'status line' above the graphics window. If you're careful you should be able to get it positioned as you need it to be.

Of course, this will all be moot when you update to NX 9.0 as you'll have no problem using the new 'Raster Image' function to position the image exactly as you wish to.

Hi John,

It's exactly the method I found but in my case I was not able to rotate 1 or 2 degrees

As I am a beta tester, I tried the new method to add raster image in NX9. The enhancement is correct but I found a bug already reported 2 days ago in phase 15 by me.
When opening a part with new raster image, an error occured, the image doesn't appear and the part can't be saved: did you encountered this problem ?

I'm running phase 16 but I can't reproduce the problem you've described. Perhaps if you send me the phase 15 version of the part file as well as the original raster image file I could test it.

Hi John,

I was able to reproduce the pb and I found a WA

New Part
Add raster image
Save and close the part
Open the part => OK

Add a sketch
Save and close the part
Open the part => the problem occured

Let me know if it's OK in phase 16

So, the WA wiil be to create a sketch first !!!

In fact my WA doesn't always work , so John I am waiting for your feedback

I was able to open the part without the sketch but I get an 'Internal Error' when I attempt to open the part with the sketch. The part opens but I get the error and the image is not displayed nor is it selectable. Is this the part that you opened the PR against? If so, I will NOT open one.

Hi John,

It's not the same part.

Did you try to reproduce the same steps with an new file and another image ?
