Image width difference from flash and photoshop while rotating

[A_kameshwaran]

Hi,

     ->     I have loaded a image in the flash and a copy of a image in photoshop.

     ->     Then i have checked the width of a image in both the application and they look same.

     ->     In flash window>transform>angle i have given angle 0.7

     ->     In photoshop Image>Image Rotation> Arbitary i have given angle 0.7

     ->     I have checked width of a image in both the application and they are not same.

     Couldn't able to figure it out the reason for the change. Could any one assist me for the same to acheive the same.

Thanks and Regards,

Kamesharan A.

Are you using 3d transform rotation? If so then the perspective setting in Flash will make it appear differently.

I have not used any 3d transform for rotation.

Something like 0.7 won't really show up very well for an example so here's PS CC and Flash CC rotating (approx) 200x200 px red square 20 degrees. They look pretty exact to me (although drawing and placement was done by hand so the slight difference in position is me). Rotation looks good.

Here's what I get from measuring width (but of course the width is of the rotated object), 256px or so on both:

For hand drawn 200px squares (one is 199.2px, etc) that's showing you it's pretty exact.

Mind you if you do a Image Rotation (I did a transform) then it will rotate in Photoshop via a different point. The rotation of the object itself looks the same (and the width is 257) but it's just positioned differently.

Your results should be similar.

Ya. you are correct. I have checked in both flash and photoshop by giving rotate angle 20. Width's are same.

But in my case it will be 0-2 will be average rotate. value will be with decimal (for ex: 0.73823  - 1.342555). In this  case width/ height gets differ for around 5 - 10 px.

The purpose of doing this rotation is to straiten the text whch are slightly slanted and saving it.

Hmm, I'm not getting that inaccuracy.

I went in Flash CC and made a square 200x200. I rotated by 1.3.

I went in PS CC and made a fixed marquee 200x200 square and again transform rotated by 1.3.

In Flash it measures to 204.35, in PS it reports 204:

Can you confirm the same steps producing a different result for you? If so, which application is incorrect and what are the values?

Hi,

     please find the below screen shot where you can fin 4px difference, if image height is high difference goes high.

Kindly let me have your thoughts.

My thoughts are, is your OS in 96DPI mode? Your Photoshop file is in 96DPI and if you have a typical system, it's in 72DPI (less pixels). So Flash would import and use the image as a 72DPI file.

Try converting that 96DPI 1024x768 file in Photoshop to 72DPI (at 1024x768) and perform the same rotation. That should account for the pixel difference.
