[Plugin] Texture Resizer (1.5.6) — updated 15.05.2013

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!

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

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.

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.)

Do you know if the same bug exist on mac SU, materials are handled differently [I believe], also, does your sips version work exactly the same as the IM version?

A request/query I have considered is, could the originals be gzipped and stored in a way that survives a standard 'purge unused' and than be optionally reinstated for high quality rendering?
I suppose the gzip could be external for smaller, overall file size, but would be better self contained if you just need a textured model to work on.

For this plugin, sips can do everything that my plugin does with ImageMagick.

I have thought about somehow keeping the originals somewhere, but I wasn't sure since it is not much related to the resizing itself and it would require 2 options in the UI (export + import). Before I had come to a decision, TIG has done this awesome script:
TextureSwapper http://forums.sketchucation.com/viewtopic.php?p=365582#p365582

brodie

I'm really excited about this script, but I'm a little confused on the usage of this script as it doesn't seem to work as I assumed it would. My assumption was that you could open a model set the percentage to 100% and the max resolution to 1024 and any textures that were larger than 1024 would be downscaled to match that resolution.

So far as I can tell though that doesn't work on 2 accounts. 1, it looks like it only affects textures you have selected. 2, with the percentage at 100% it seems to ignore the 1024 max resolution setting and does no resampling. Instead you have to set the percentage to, say, 95% (99% didn't seem to work) for it to downsample to 1024.

Is this currently how it works or am I missing something? In my opinion these are limiting factors for the script as I don't always know what the resolutions of the images are and if they're already 1024 I don't want to further downsize them every time I run the script. Also, having to select all the textures opens me to the distinct possibility that I'll miss some textures which could be too large. And it takes longer of course.

Is there any way to universally downsize all textures larger than 1024 to that size?
