[Pro] Rotated jpegs gaining unrotated background color

Some jpegs images that I rotated a few degrees have gained an unwanted unrotated background upon publishing. Other similar ones are fine. I don’t get it.

I’ve tried re-creating them and also re-using the graphic box of the good ones, to no avail. Any thoughts on to why this is happening and why inconsistently?

Not sure if you mean the marria9a image - but it is a gif and so not very good for continuous tone and give it a ‘spotty’ effect. Try as a jpeg.

No, it’s the first of the three caricature art images in the page.

It also happens to the artwork image on this page:

I’ve found another possible clue to this issue: The unwanted background goes away if I remove the overlap of the problem jpeg over its neighboring image. Replace the overlap (much preferred) and the problem returns.

So inconsistent – I overlapped other jpegs the same way. The types of files and Inspector options for those that worked fine appear to be the same, but this one balks.

I managed to get rid of the unwanted bkgrnds by changing the the Inspector’s Graphic Item Type to GIF (not my preference for a simple rotated rectangle).

It worked but it’s still inconsistent, since other rotated and overlapped jpegs didn’t have the problem. So if anyone understands why this would be the case, I’d appreciate your thoughts.

To retain quality try choosing Png instead with millions of colours which will retain transparency of the graphic container.

Nothing unusual here:

Web knows three valid types of images:

JPEG, GIF and PNG.

While GIF and PNG both can handle transparency - JPEG can’t.

If you rotate an image in Freeway, its container is still even and unrotated, illustrated by the thin dotted line round about the image - right?

While JPEG doesn’t know about transparency it needs on each 4 created triangle in the corners a filling (grey in this case - but it could be everything). That’s what happened here.

So you got two possibilities left:

GIF and PNG.

What to choose depends on the image (content) itself. PNG (millions) can blow up file-sizes but is probably the best choice here.

Web Design doesn’t know specific personal attitudes - it simply follows an easy formula which could be read as:

“The truth is in the browser!”
