Re: Rotation per default not around center but NorthEast corner of image

Quite honestly, when i try to even wrap my head around how to calculate this, my brain goes into temporary shutdown and all i get is white noise ..

Generally i understand it this way:

The best solution for me is to calculate the center of the bounding box of the rotated Image.jpg and calculate ...

Re: Rotation per default not around center but NorthEast corner of image

Thank you for your responses. I'll see if i can derive an automatism from what was posted.

Generally i should have added that i wouldn't have a problem fixing this for this one example by changing coordinates, but this is all done by automated scripts and they are fed with coordinates and angles ...

Re: Rotation per default not around center but NorthWest corner of image

I understand the confusion.

Let me explain more properly, with a better example and some files.

I have two files: Image.jpg and Overlay.png

Image.jpg is this:

Overlay.png is this:

https://i.imgur.com/ViZsLrf.png

It has a cutout.

The goal is to rotate and ...

Rotation per default not around center but NorthEast corner of image

I am trying to place a rotated image onto a blank canvas.

This is the command i am using:

convert "(" -size 1000x1000 xc:transparent ")" "(" "img.jpg" -virtual-pixel white -rotate -10.75 ")" -geometry +136+148 -composite out.png

I would expect the image to appear at +136+148 rotated around its ...

Re: Invalid color profile for colorless images in RGB colors

I ended up re-embedding it because for whatever reasons in my tests i found that in the final TIF i am left without the original profile unless i explicitly do so.

Photoshop states:

"The embedded ICC-Profile can not be used, because the ICC-Profile is invalid. The profile is being ignored."

And ...

Re: Invalid color profile for colorless images in RGB colors

Yes, when i open the original image, things are going just fine. Photoshop is opening it without a hassle.
But after processing, there is the error.

This is the original image:

This is the processed one with the embedded original profile.

Re: Invalid color profile for colorless images in RGB colors

Thank You for your input.

The problem is that this runs in a huge print company. I cannot afford to modify the color information in any way, as it must be printed according to the client's needs.

Invalid color profile for colorless images in RGB colorspace

Hello,

i am experiencing a rather confusing issue. The procedure is as follows.

1. Extract color profile from image
2. Do some image processing (resizing, resampling, etc.)
3. Embed the original profile and create a TIF

This works really well, with one exception. If the original image that is ...
