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.

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...

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.

Wow. I didn't even realize Seashore was still being developed. Thanks.

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.

Another benefit of this program - it's about 1/20th the file size of GIMP.

GIMP and Seashore are two different-goal applications.

GIMP is like Photoshop.

Seashore is a drawing app like Illustrator (very, very lite.)

GIMP has so many features crammed into it that it naturally has a much larger file-size.

amake replied on 05 Apr 2007
Yeah, it also has about 1/20 the functionality.

And to the other commenter: No, actually Seashore is NOT like Illustrator at all. Illustrator is for vector graphics; Photoshop, GIMP, and Seashore are for bitmap graphics (with some, limited vector capabilities).

I get a "too many processes" error message when I try to open the image file.
