Uploading An Image But Keeping Size Restrictions

How can I upload an image that let's say for example its 330x248, I know it doesn't conform to the conform to the 256x256 or 256x512 rules, those types of size restrictions. I want to upload it as is, no skewing or anything.

You can upload it as is, but it will be skewed. You would then have to resize the prim to picture's proportions so it would not appear skewed.

The other option is to skew it yourself in your image editing software, so that when it is uploaded, it comes out in the correct proportion.

OK let's say, could I make a 512x512 image, put my image on top of it, make the background transparent, save it as a TGA and upload it that way? Then the image will be the right ratio, and the transparent part would disappear. Can I do it?

You could... but couldn't you also just resize a prim so it appears in the right proportions?

Say... 300x200 pixels on a 3m x 2m x 0.1m cube?

I'm not clear what type of images you're uploading - is it pictures, textures or something different?

You know you can change the 'repeats per face' in 'default' and 'repeats per metre' in 'planar' on flat surfaces, yes?

That's a creative solution. You could do it, but the only thing you would have to worry about is calculating the proportion on the prim, and the horizontal and vertical offset of the picture.

This would only be problematic if you put it on a 10x10 and want it bigger.

Is there any way to convert pixels to the length in SL? Or is there an easy way going about it?

It's photos.

And no, I was not aware.

what's important for resizing a prim to a textures dimensions is not it's size, it's the ratio...

your 330x248 breaks down to a (simple) of 3.3x2.48 multiples or fractions of those dimensions will work for your prim

also just so you know, it's better to resize your image to a power of 2 on each side on your own, since SL's conversion is a bit sloppy... include the original ratio in the file name and you'll be able to easily see it when you add it to a prim.

it might be useful to read the stickies in the texturing forum, to better understand SL image size requirments (which are based on openGL's requirements)

Actually if you save your picture as 330x248, 24 Bit TGA File on upload to SL it will get automatically converted to a 256x256 file.

From there on apply it to a 10x10 prim (example only) then select the Stretch Textures box, then resize the prim and it should automatically come out as you want.

If you would like a more in depth explanation there are some stickies at the top of the Texture Forum that may answer your question in more detail regarding why and how SL resizes textures.

Not even. The resulting image would be 256x128.

Its good to know what size prim face the graphic is going to go on. If your going to put it on a prim face 3.4 x 5.1 make your graphic 340 x 510 then even though it gets loaded up as 512 x 512 or even 256 x 512 when applied to the prim it will fit perfectly.

Apparently, I must be missing something here. I am an artist, and I never worry about the size of the images I upload, and well... they All look damn good! The largest I have uploaded is 1024 X 700.

Similarly you can reverse the process and fit the prim dimensions to the image, which would probably be better for a photo. So for a photo that has dimensions as in your example Pleasure (330x24, just make sure the dimensions of the prim that you are texturing have the same ratio e.g. 3.30x2.48, 6.6x4.96,10.000x7.515, etc

You really should think about the size of images uploaded, not just for proportions, but for overall size - a 1024x1024 file is 4x as large as a 512x512 file - too many of those and resident's PCs are going to start having problems rendering them all on their machines. 128x128 to 512x512 should suit most purposes, with 1024xX files needed very very rarely. Chosen does a much better job than I ever could at explaining why, and so I will link you to it!

FYI, I actually tried this before posting my answer and the results were that the texture was converted to 256x256 not 256x128 as you mention.

I think I understand, it's just that the image gets screwed up in the previews is all.

Yes, the preview will always show you a square, but it doesn't mean that it would be the final resolution.


Anyway this thread should be moved to texturing tips where people know more about it.
