change an image color

[Floezen]

Hi,

I'm trying to change an image color with MagickWand. Unfortunately, nobody could help me with this problem in the MagickWand for PHP Forum (viewtopic.php?f=10&t=12388).
But actually the question is not MagickWand specific, but a general ImageMagick question:

I have a picture which I want to colorize with ImageMagick as in Adobe Photoshop with a color angle of 33° and a saturation of 17.

The original picture looks like this:

The result should look like this:



When I tried to do this with an imagemap th result unfortunately looked like this:



( please see also my topic at viewtopic.php?f=10&t=12388 )

Can anybody tell me what I did wrong or what other function would fit better - and maybe tell me how I would need to writ this?


Thanks allot for your help

To my eyes, your two results look the same. What is the difference that you are concerned about?

There are missing colors. The color spectrum is not large enough...
It looks like a 255 color GIF. But what I need are high quality images.

I have seen some other complaints about the resulting IM Gif format, but don't know if they have been resolved.

Have you tried saving as png rather than gif?

Oh, it is NOT a gif, it just looks like one!

If it were a gif, i'd know, what to work on...

OK, if it is a jpg, then possibly try a different compression or check your version of libjpg delegate? Or try saving as png. If all else fails, then suggest you report to Bugs forum.
