[Plugin] Texture Resizer (1.5.6) — updated 15.05.2013

thomthom

I didn't notice this plugin until now.

I see you're using ImageMagik - if you are willing to require that the users have a recent SketchUp version ( SketchUp 8 Maintenance Release 1 ) then you can use Material.write_thumbnail to write out smaller versions of the material's texture.

http://code.google.com/apis/sketchup/docs/ourdoc/material.html#write_thumbnail

Cross platform, native to SketchUp, and doesn't require dependencies other than an updated SketchUp 8M1.

Aerilius

Thanks for that tip! I haven't found it or thought about it. That's probably the most straight-forward way to do the current features cross-platform and inside SketchUp. I'll test how it works with different resolutions.
On the other side, ImageMagick is very powerful to do more advanced image manipulation (I've thought about cropping, distortion and more features) and for higher-quality output (Sinc-Lanczos).

thomthom

Yea, it's much more limited in the output. You cannot specify compression level for JPEGs for instance. And the output must be at least 1px smaller than the original.

But it's a nice little addition to the API that might be useful.

thomthom

Ah yea... that is an annoying limitation...

Aerilius

I tested Material.write_thumbnail and it failed too often. It seems there are absurd limitations. The resolution argument only accepts values that are 1px smaller than the smaller length of [width, height], but "resolution" is always applied as the maximum length. Thus an image of 102433 can only be resized with resolution=32, whereas resolution=31 fails because 31(33/1024) < 1, so you never can get 500*16.

Thanks! I've been wanting a plugin like this. Nice work!

thank you very much realy great work respect
i hope google see whats going on here on the plugins front

Hi Aerilius,

have managed a Mac install of ImageMagicks using Homebrew http://mxcl.github.com/homebrew/ the nice thing is it sorts out all the dependencies for the system it's running on...
I now get this in Terminal,
%(#0080BF)[$ which convert
/usr/local/bin/convert]
but I get your 'install advice' in SU

also, I get... I can pull more details if you want...
%(#0080BF)[$ convert -v
Version: ImageMagick 6.7.1-1 2011-10-27 Q16 http://www.imagemagick.org

$ convert -list type
Bilevel
ColorSeparation
ColorSeparationMatte
Grayscale

Optimize
Palette

I had to completely get rid of MacPorts before I had any joy compiling [and reinstall my system ruby that MacPorts had modified...]

I'll try some things Saturday night, soo if you have any ideas let me know.

hi Aerilius,

the default text is still not appearing and neither is any obvious "Goldilocks' integration...

thanks for the thanks, but it's all your hard work, I'm just playing and making your life harder....

john
PS. can you reply in the thread as well, I don't get the notifications when you just edit the head message,
is that standard?

Both indicate that I didn't get the javascript started in Safari. I hope I fixed it now in 1.2.1

reloading dose nothing different... except mess up the resize the first time but that's the SU topdown nonsense...

I just tried

<button onclick="puts(s)">Defaults</button>

and get ReferenceError: Can't find variable: s

1.2.2 is working a treat on Mac 10.5.8 so I did a test with the now integrated Goldilocks settings.

for a test I grabbed a 'Velux slideshow' from the warehouse, ran goldilocks to see what the texture sizes were

ran Texture Resizer set at 4 and pulled 0.2MB out of the file-size, then re-ran at 1.2 and got a small additional reduction in size of 0.1MB.

The original was only 4.1MB so reducing it to 3.8MB without any noticeable degradation in 3-4 mins is pretty slick.

I did have one projected texture that needed re-positioning.

hi,

here's the latest mac screenshot, after I added that 's'.....

looks great.

Aerilius

It finally looks really great, Thanks for all your help!
It's probably time to make a real Ruby Webdialog toolkit so that webdialogs don't look anymore like websites, but like native OS dialogs.

@driven said:

I have no idea what could cause this. The plugin doesn't touch UV coordinates but just replaces the texture images. Since SketchUp changes the aspect ratio and scale after re-importing, the plugin has to override it again with the old scale (it should work, but maybe there is a problem). Can you give me a link to the Velux model, then I can have a look tomorrow?

Hi,

Great plug-in but I'm having serious problems.

When I apply any changes no matter what settings are ticked, it messes with all the colours really badly, haven't got a clue why its doing this?

I've attached 2 thumbnails of before and after.
cheers

edit; just updated to the latest version but its not working? attached another screenshot below of the blank window i get

Sorry Luke,
the blank screen, thats the missing "S", I referred to..
the "TextureResizerOptions.htm" file needs the 's' added to it's name,
[in Finder, select file >> then return >> then right arrow >> add the [s] >> click out.]

Luke, what format are the texture files?

Also, I always use Goldilocks first to get an overview at the screen size I think people should view at, then select and reduce.

john

@Aerilus, the windows surround curved sides, complete 'slide' shows the problem http://sketchup.google.com/3dwarehouse/cldetails?mid=b74580f8fed2b7691ae371d97b34cb90

awesome all works now I updated to the new version and changed the file name!

Lersince1991

I have a suggestion:

Could you have an option to stop it from upscaling images when using the px/m option please?
Nothing is gained but its cancelling out the point of downscaling the images. i.e. some images go down in size reducing the file size, but some image then get upscaled increasing file size and your back to where you started.

This would be massively beneficial and allow me to get the best file size / quality.

Maybe you tried this...
If you preselect 'ALL' then deselect the ones you want 'untouched' then open 'TR' it's in a different mode, that only adjusts the selection...

Do you still have this issue?
I also had a serious problem with colors: In the materials dialog, SketchUp offers two options, either to change a color tone or alternatively to completely colorize a texture. When I reload a texture, SketchUp resets the color tone to normal. Because of that I wanted to set the plugin to apply the previous color tone again, but due to an API bug SketchUp then sets always the colorized state. So I thought my workaround would just leave the colors how they are defined in the image file.

@lersince1991 said:

Did you have a case where it upscaled the images? The plugin should automatically skip textures that otherwise would be upscaled (if you keep the Ruby console open, it will tell you when this happens).
(The percent option does not have this limit, so when someone inserts 200% it obviously does upscale all.)
