Exactly replicating the ColorToAlpha to MagickCore

PHP - trying to define two color stops for a gradient background area where users can select both colors with a color picker

QUESTION

Exactly replicating the ColorToAlpha to MagickCore

Asked 2020-May-19 at 05:40

So I have been trying to get the GIMP-like Color-To-Alpha in the MagickCore C API. But there are some issues that I have been facing with it. I tried to look at Fred's scripts It does not really replicates the GIMP's Color To Alpha exactly, since it is calculating the differences but does not seem to do same minimizing/maximizing as GIMP

Basically, this is the formula original_pixel = required_pixel*alpha + color_made_into_alpha*(1-alpha). I know the alpha for each pixel, I know original color, and alpha color too, so I want to know what should be the required_pixel to satisfy it. Basically, required_pixel = (original_pixel - alpha_color_pixel)/alpha + alpha_color_pixel. I need to use it in image efficiently. Using fx doesn't helps much I will appreciate recommendations

This seems to work for me with the following image, but you have to use ImageMagick 7 or compile ImageMagick 6 for HDRI.

QUESTION

PHP - trying to define two color stops for a gradient background area where users can select both colors with a color picker

Asked 2017-Aug-24 at 22:39

PHP - trying to define two color stops for a gradient background to be applied to a single CSS selector. I need them to be individually selected by the user (via a color picker).

I've been defining the background color with PHP (named: $color_gradient & returning: '#f7f7f7'; as the default for users to start with) so the user can choose the base color of the gradient (via PHP), and then I have color-to-alpha gradient overlays set in the css (so the background color chosen by users fades to a black or white ending color) to get an effect closest to what I'm trying to accomplish, but it is still rather limiting to whatever color I've set in the CSS for the overlay, and I don't want users to have to edit the color codes in the css file - I'd rather just have PHP handle it so that the user can define both colors of the gradient instead of just the one.

In CSS, gradients use background-image. Try defining variables in your function for each color and the direction; for example:
