Hi,
I have a web application used Imagick to generate image.
Then I open the image width Photoshop CS5, view Image mode, it is Indexed color
But if I open the image width Photoshop CC, view Image mode, it is RGB color.

The image here:



Can someone help me ?

Exiftool is probably the most reliable method of finding the actual formats of images in files. It says this is indexed.

I want change from Indexed to RGB, how?

[snibgo]

convert 1.png -define png:color-type=2 out.png

this works also, since your image has transparency

convert 1.png PNG32:1_new.png

Sorry, I do not know how to do that in Imagick.

Thank you all.

I want the image was created is RGB and it will display exactly at all Photoshop version.

It seems difficult

Assign it a profile, if the input image does not have one (sRGB or Adobe profiles).
