Thank you for creating this App! I have been using Gimp in the past, but this one integrates much better with macOS and has all the (basic) features I need (probably even more).

Runs fine on Mohave. In DarkMode the Point Information which has been moved to the sidebar is too light to be easily read. Other than that minor cosmetic flaw, this old workhorse is as good as ever.

Seashore 0.5.1 now works on High sierra after NOT working under Sierra. Deselecting all of the boxes under Preferences stops the random crashing. This is a pretty fair image editor and clean-up tool, an oldie-but-goodie.

I had never tried Seashore because I mistakenly thought it did not have a crop feature. There is no crop button in the tool palette, it is listed in the edit menu instead. A promising looking app that I look forward to using.

Finally found a image creation / manipulation tool for the "you and me" with a simple interface and the extra features one might miss by using Paintbrush or another Paint clone. Excellent work! Highly recommended!

It's a great little free bit of software, very pretty, and also quite easy to use once you get the hang of one or two little tricks. I did manage to crash it a couple of times, mainly when I tried to use Transform on a selection rather than a layer, but otherwise it's stable enough. There are a couple of serious omissions though. Although you get Exposure, and Hue/Saturation, you don't get Levels, or Colour Balance, both of which I think absolutely essential in any layer-based image editor. But, for a free app, it's neat. Just make sure you download the 0.5 Beta, not 0.1 which has far less in it.

0.5.1 Great application, considering the price. The one-window interface and mac-likeness draw me to use it. Instead of waiting for X11 to launch. Some 10-15 minutes of fiddling and You find all the basic tools and effects...furry, blurry, hurry...Is that your mother? Both drawing tablets, Graphire4 & Intuos4 worked "out of the box." Biggest bug : Tablet eraser does BG color.

Check out version 0.5 at the following link... http://seashore.sourceforge.net/The_Seashore_Project/Download.html it is unbelievable that such awesome software is so readily available for free... may lack a few filters that you will find in things like pixelmator, but this is the most mac-like graphics program I have used in term of ease of use. Hope they keep up the development as this program is one of my most used programs on a daily basis - especially since the new version came out. NOT ONE CRASH WITH THIS PROGRAM EVER

I've been watching Seashore develop. I keep hoping they'll add more of Gimp's effects. I've become addicted to live previews in other apps, I hope they'll add it to Seashore. Overall a good little app if you don't need all the power of a Photoshop or Gimp.

Not too bad. I think Seashore has potential! Here are my wishes for improvement: - Alt-dragging to automatically duplicating selection (á la Photoshop). - Realtime transparency interaction. I.e., be able to show (in realtime) when you change a layer's transparency. - Command-+/- for zooming. - Scroll-wheel support for zooming. - Option to not let the screen dim when you make a selection. Plus, alternatively adding an option to use a more 'conventional' type of marquee (again, á la Photoshop). - More enhanced gradient editor. - Do I dare asking? Bezier-curves/simple vector gfx support? :) Good luck! And thanks so far!

this is a very promising app. for only being 0.1 it's very well done. seashore is extremly fast and comfortable to use. sure, there is still a lack of functions but basic editing can be done very easily and i think more features will be available throughout the next versions. what i'd like to sea most would be a stamp tool like in photoshop.

Very nice beginning! I have a few wishes: 1) I wish it had editable text layers. 2) Text tool automatically create new leayer for each text entry. 3) Paintbrush, Penil and Smudge tools could have option to show it's real size, not just center crosshair. 4) Gradient tool could show direction line when I drag it, to give me better idea about the direction. 5) Gradient Style options could be shown as buttons, so won't need to open menu to set desired option. 6) Selection Tool options could be shown as buttons, so won't need to open menu to set desired shape. 7) Actually Options section could have it's own section in the palette, so I could have it always open. Brushes and Textures could be also separate sections below each other. Maybe something similar to the OmniGraffle palette design? - I can detach each one and move where I want, and I can "stack" them into one tall palette, if I want to. 8) Why not use Photoshop Zoom In/Out/Fit shortcuts? (Command+=/-/0) It's industry's standard...

Very nice, hope it will in the end get all the functionality of Gimp. What I really don't understand though, is why the developper copied this rather alien interface from Gimp. I mean, if you're improving the interface of an app by cocao-ising it, why not go the whole way and dump the senseless amount of gimp windows floating around?

unbelievable app. this is certainly commercial quality-it is 100% cocoa, so it's not slow like GIMP or other carbon or java apps (in fact, it starts up and runs very quickly). beautiful work-it's a very simple, lightweight, easy to use image editor with the only the features that matter the most. perfect for when i need to do some graphic editing.

I had a picture I wanted to texture to look like fabric. Couldn't quickly figure out how to in GraphicConverter, so I went to MacUpdate, figuring I could find something. Downloaded this. Wow! It actually did what I wanted it to. I was able to figure it out and finish my project very quickly, even though there's very very little documentation (not even tooltips). The interface is pretty intuitive. Add tooltips and it would be awesome, I think. Also: no crashes. Keep up the good work!

As a user, all I want is Gimp in a native interface. Once you get all of Gimp's features ported over into full standard Quartz interface, then focus on optimizations for G4, Quartz calls, and the CoreImage subsystem of MacOS X 10.4 Just letting you know what I want as a user. In the mean time I'll stick with X11 Gimp. Keep up the good work!

This is more then I can expect from a 0.1.3 app. Its great and fully native. WOW! I hope it will be a photoshop killer in a few days and its open source. I played it for a few minutes and I got the user interface and it has easier and better GUI then any other professional app out there. I liked it very much. Only one thing, and that is the ruler is missing. I expect advance photoshop features in Tiger with coreGraphics.

This is a wonderful app, so far. One of the things it needs, though, is to add Script-Fu support. This method of scripting the GIMP is one of the reasons it became so popular on Linux, and it would be a major asset on the Mac as well. Obviously a more Mac-like scripting interface (perhaps OSA support?) should also become a priority later, but compatibility with existing GIMP scripts would be a major short-term boost. This said, the app is off to a wonderful start, and I look forward to seeing it mature.

just a suggestion... You would be best off specifically targeting Tiger. Having a first out of the gate app that takes full advantage of Core Graphics would be an unbelievable coups for open source. That's not to say you shouldn't continue to work on it for Panther. But, complex image filters should be left for Tiger, where they are in the OS. You would have a tremendously influential app then.

In short: Great idea, right path, please keep going. :) Much more stable than I expected, this little app already offers several of the most important features. Naturally, it needs a lot more of them, but for this early state, it shows lots of potential. Comparing it to GIMP shows us how much a true OS X integration is worth these days. Once it has all or most of GIMP's features, Seashore will be a killer application that will be on every OS X user's hard drive. I hope that Mark (and others, hopefully) will keep up working on this wonderful project and am looking forward to see the application using Core Image technologies in Tiger. :)
