Loving the new magnifier! But I am noticing some glitches, it sometimes seems to magnify on itself, as if the magnifier is added to the screen data it's magnifying.

I've just installed ColorPicker to 1.0.0.

The triangle color remains grey, because it's hard-coded. It should set according to the color scheme.

Choosing the format for the color hexcode there should also an Inkscape code option as Inkscape is a very popular app in the Open Source world.

(Followup from my comment on #36)

I have a similar (same?) problem.The magnified view updates with much slower framerate than my mouse. I don't know whether that's because of my display being 4K (more stuff to process? bigger image to magnify?) or something else.

Also, moving one pixel on a touchpad is really hard :) But tools like Shutter do somehow make the mouse movement result in less-than-pixel cursor movement. Maybe that could be an inspiration? :)

You asked:

Maybe you could drop your System configuration for debugging purposes.

I'm not sure, did you mean this screen? ⬇️ Or should I run some CLI tool that collects HW info etc?

Here's a screencast of the issue.

If you want me to test / debug something, I can compile the app and try something - just give me some instructions :)

Hi,

I seem to be having an issue with this amazing app. When I click pick color, there is a lot of screen flickering and artifacts around the magnification area. The moment I click an areas to sample colors, then the flickering and artifacts end. I have attached a screen grab of what it looks like.

After I clicked on "Choose Color" - Button there is no way of canceling it ( Or it isn't written anywhere).

The app should remember the last used color format.

Color history should not show the same color twice. Otherwise, the user might lose other colors saved in history if he or she selects the same color twice by accident.

(this is not very useful)

since debhelper doesn't support meson yet, you'll need to make a custom rules file. You can see an example here

It would be wise to not only keep a history, but allow for an extended history, saved to a file, and probably organized by groups.

Pick Color Picker has a similar feature (except for no grouping).
Unfortunately it hasn't been updated in a while.

It looks like your screenshot shows a non-default position for the close button. You should make sure your screenshot shows your app using the default elementary OS settings

Just installed in my system and the app don't work.
Doesn't matter where I click, I only have two colors in the history, gray and white.
Also the magnifying lens don't show the color I am hovering on the screen,
it stays with weird artifacts.

Later on I'll try to compile myself to see if there is any change in behaviour.

I don't know what is this error called. You can see error in this gif.

And this is my computer specification

Thanks for submitting your app for publishing on AppCenter! Looks like there's a small issue in your .desktop file. It references a generic icon instead of the icon you ship

Hey there. I was testing a LiveUSB of an Arch-based distro and happened upon this amazing ColorPicker package in the AUR (https://aur.archlinux.org/packages/color-picker/). It installed and worked perfectly and is the best color identifier package I've ever used. When I switched back to my Debian-based distro installed on my laptop I attempted to install the package once again. This time, however, nothing I did worked. I tried downloading the .deb package, git cloning and building from source, and even adding ElementaryOS's PPA in order to install its dependencies. Unfortunately none of these options worked and I still cannot get it to install. Is there anything you can tell me which might help me out? Might it be possible to convert the ColorPicker to another version that does not require Granite (the dependency that seems to be the most problematic).

Thanks for any info you can give me! Happy holidays!

It would be cool if there are a simple color slider to manipulate the color that we've already picked the color of.

Hi! I bumped on problem when building rpm in OBS:

Right now it appears color history is wiped out when closing the app. It'd be rad to save that state so I can pick a color, close the app, then come back later and have that history saved.

Current situation:

It is very hard to go "one Pixel left or right". This is a problem in complex pictures where to hit the exact pixel.

Situation: Find a way to just push the mouse for one pixel in a direction.

Possible solution: In color-picking mode if you hit the arrow keys mouse just goes one element in the direction (arrow left -> mouse goes one pixel left etc.)

It'd be handy to remember the window position of the app, i.e. saving to a GSetting when closed.

Since the color picker cursor starts right when you open the app and I often want to pick a color from the middle of my display (which is where Color Picker opens up right now) it's often in my way.

If it saves its window position, I can move it to the corner and have it always open back up there, out of the way.

I know that this is not the main purpose, but it would be quite intuitive if I could input a color code in the specified format(e.g. if HEX is selected I can input #FF00FF) and then the color picker

1. shows the specified color
2. lets me convert the color code to the other formats.

Hi.
Can you provide a flatpak on flathub.org please?
It's a very good program but no rpm package!
Thanks.

It isn't easy to pick a certain pixel because the current mouse cursor is quite inaccurate. Therefore a magnifier or something similar should be implemented.

App works on x-session but cannot pick colour on wayland.
I'm aware it's related to security reasons behind wayland.
Just mentioning it, if anyone wonders why it doesn't work for them.

More info here:
https://gitlab.gnome.org/World/gcolor3/issues/38

It'd be cool if a notification appeared when the copy to clipboard button is clicked.

Its really simple to implement, example here: https://github.com/keyilan/swatches/blob/master/src/MainWindow.vala#L438

Translating appdata.xml file will help people to know about your app in the AppCenter. For example mostly French users won't download the app if it's description is in English, 'cause they will think that the app isn't translated and won't take time to read if its not translated.

I love that it has a history... I often design sites and apps by picking three of four main colors.
but it would be sooo much quicker if they included the rgb hex number right in the history.
Above #999999 using black and below using white for visibility maybe?
Then you could see them all at a glance.

Once you select a color with the magnifier, it should automatically copy the color code to the clipboard. This is the way other color picker programs I've used work.

Right now, one has to pick the color and explicitly copy it to clipboard. Combining this two steps into one would make the app easier to use I think.

If I click on a colour in the colour history the arrow indicating the colour changes immediately instead of a smooth animation. It would be neat having an animation.

Since your app deals with graphics you should add the Graphics category to your .desktop file in addition to Utility. Adding more categories will help people discover your app.

You can see the list of accepted main categories here and additional categories here

I want to sample the RGB in floating points between 0 and 1. This is very useful for glsl. Thanks for the software.
