Hi,

This is a small tool to create simple gradient wallpapers with color of your choice.

Special thanks to: Solo, smokey01, musher0 and Barry K

Thanks for this, trio. It can be quite useful!

Posted: **Tue 19 Jul 2016, 13:48**

A couple of try-outs!

You're doing some nice work there trio!

If you really want to get your freak on. You may want to experiment with filters a bit. The results can be quite spectacular.

For instance, you are able to add noise to your wallpaper using the feTurbulence filter.
If you go to this page:

http://docs.webplatform.org/wiki/svg/tu ... vg_filters

, there's a whole lot of useful stuff about filters. The bits concerning feTurbulence, feColorMatrix and feComponentTransfer are particularly relevant.

I was dabbling around a bit with those filter functions, and I came up with this:

Code: Select all

<svg xmlns="http://www.w3.org/2000/svg" width="640" height="480">
<defs>
	<filter id="myFilter01" x="0" y="0" width="100%" height="100%">
	<feTurbulence baseFrequency=".005" numOctaves="1" seed="6" type="turbulence"/>
	<feComponentTransfer>
	<feFuncA type="table" tableValues="1 0"/>
	</feComponentTransfer>
	</filter>
	<filter id="myFilter02" x="0" y="0" width="100%" height="100%">
	<feColorMatrix type="hueRotate" values="180" result="A" />
	</filter>
</defs>
<g filter="url(#myFilter02)" >
<g filter="url(#myFilter01)" >
<rect width="640" height="480" />
</g>
</g>
</svg>

Now, the thing is, I am running Precise Puppy, which has librsvg version 2.34 as an svg rendering library. That particular version has some severe limitations imposed, because at the time of its release, they discovered you could use some of those same svg filter definitions to introduce code from outside sources. So they crippled it, basically, which is why I can't have an svg as a wallpaper, and I can't have an svg GTK standard iconset.
You're probably running librsvg 2.40, so you do not have that problem.
So what I am saying is that I do not know how it looks as rendered by librsvg as a wallpaper.
I know it looks kind of pretty in Inkscape, and I know it looks kind of pretty in Firefox, and I know it looks like shit in the Gimp.

It's really weird, each program renders the image differently, which, I suppose, has everything to do with how it handles the Alpha channel.

Interesting stuff!

V 1.7: Lots of stamps! see main post

@solo
I'll look at those filters

@musher0
Thanks for trying out!

V 1.7.1: small upgrade - stamps size now in 4 sizes

Posted: **Fri 22 Jul 2016, 07:47**

V 1.7.2: Add stamp shadow effect

I am able to make the text shadow also, but the effect is not satisfying (ugly). This svg thing is quite confusing.

anyway, this app is not as simple as when it started

Dear trio,

Great work, and thanks....

With kind regards,
vovchik

V 1.8: Background base filter effects, now shadow not only stamp, text also

Note: the effects aren't looking good for flat-1color background

@vovchik: thank you for using

V 1.8.1: Bugfix flatbackground now can have shadow effect, adjust text stroke width and text shadow a bit

I realize it's a bit of a weird request, since I'm not able to succesfully run your wallpaper maker on the Puppy I use, but I am very much interested in what it is capable of now, so I'd like to ask if it would be at all possible to post a sample wallpaper image.

Because it seems like you are lifting it to a whole new level.

@solo

What puppy? this app is only bash and gtkdialog, should work for all std puppy

Posted: **Sat 23 Jul 2016, 17:11**

Really great stuff trio!

The problem for me, as I explained in a previous post, is my librsvg version, which is the library used for rendering svg's.
Precise Puppy runs librsvg version 2.36, which has problems.
