| I have a question about MagickCombineImages() on C API, y want to achieve

|
| convert separate_red.gif separate_green.gif separate_blue.gif
| -combine rose_combined.gif [*]
|
| [*] http://www.imagemagick.org/Usage/channels/#combine
| -
|
| but, doing something like this ...
| ...
| status_r =MagickReadImage(magick_wand_r, "separate_red.gif");
| status_g =MagickReadImage(magick_wand_g, "separate_green.gif");
| status_b =MagickReadImage(magick_wand_b, "separate_blue.gif");
| ...
| magick_wand = MagickCombineImages(magick_wand_r, RedChannel);
| magick_wand = MagickCombineImages(magick_wand_g, GreenChannel);
| magick_wand = MagickCombineImages(magick_wand_b, BlueChannel);
| ...
|
| I only get the image but in yellow ... What im doing wrong here ??

All three images must be in the same magick wand.
status_a = MagickAddImage(magick_wand_r, magick_wand_g);
status_a = MagickAddImage(magick_wand_r, magick_wand_b);
now you can combine them
magick_wand = MagickCombineImages(magick_wand_r,
RedChannel|GreenChannel|BlueChannel)
I think the documentation is a bit out of date.
* MagickAddImage() docs has 'images' instead of 'add_wand'
* MagickCombineImages() docs do not mention the 'channel' argument
And the PHP version of the doc says only ONE of the channels
can be given (which was only true for OLD versions
of MagickSeparateImages() )
