[ Solved ] Blurred image

[Zetla]

Hi

i'm writting a plugin for share vessels, and my last problem is all my images are blurred.

i have the same problem for image, button, application launcher button...

here i have tested with a mod logo (mechjeb), and i have the same issue (my plugin use the MJ logo in the right, its the same with all images)

here are others images of my mod, blurred too :s

Someone have a idea ?

Thx

edit:

private WWW imgGM = new WWW("file://"+root+"Plugins/Textures/gm.png");

public static Texture2D buttonGM = new Texture2D(24, 24);

(its the same with other size)

and in my awake() method:

imgGM.LoadImageIntoTexture(buttonGM);

first thought, your images are created too small and get upscaled..

can that be the problem?

my stock toolbar buttons are 36x36px btw..

I thought it's the default..

new Texture2D(24, 24); will downscale all images to 24x24

It's likely this is the cause..

If that's the problem,

you may want to get the image original width/height first and create your Texture2D with these dimensions..

was just a guess, if I'm wrong, never mind..

There is no need to load your image yourself. Anything in GameData and not inside a PluginData folder is loader by the game. If you load the image with code you get 2 copy loaded and waste some mem (not much for a small texture but still)

Just get your texture with

Texture tex = GameDatabase.Instance.GetTexture("MyAmazingMod/Plugins/Textures/gm", false);

As for the blur I don't know. philotical is right that the stock one are 32x32.

Thx for your reply

when a load image into texture, the dimensions of the texture2D take the dimensions of the image

exemple:

public static Texture2D buttonGM = new Texture2D(1, 1);

and

imgGM.LoadImageIntoTexture(buttonGM);

at the final, the texture2D have the same dimensions of my image (38*38 for the application launcher)

(i have tested with the good dimensions and its the same)

for other image (button and foto), i just show image (i dont write dimensions of them)

exemple:

private WWW img = new WWW("file://" + GameManager.root + "/GameData/GameShare/PluginData/screenShots/screenTemp.png");

public static Texture2D screenTry = new Texture2D(320, 180);

img.LoadImageIntoTexture(screenTry);

and for show:

GUILayout.Box(screenTry, GUILayout.ExpandWidth(false));

so image appear with her native dimension

Sarbian, thx man, i go to change my code

[Zetla]

Sarbian, after change my code, my problem is partially solved!

now my application launcher button, and my button appear correctly

so i have the problem just for my foto

it's a plugin for share vessel, so i show informations of the shared vessel, and one screenshot.

so, screenshot was downloaded in game, and i think a need to load it, and after, use the 'LoadImageIntoTexture' method...?? (because game don't load when starting, and screenshot are in 'plugindata' folder)

[Edit: ninjad - partially outdate]

You said shared vessel, so I thought you load vessel pics from a web server..

but as sarbian said, no need to use www if the pics are in game data..

However: your images are downscaled and re-upscaled somewhere - it's obviouse from the screenshots..

I might be wrong with "where" it happens - but these pictures have a scale issue - without seeing more code, it's hard to confirm - but my gutt says so lol

The fact, that even the MJ pic gets screwed up prooves that my belly is right this time.

that pic gets scaled down to at least it's half and displayed larger then the RAM texture is.

you can try it in any graphic progam, load the pic, scale it down, rescale it up - you will get that result..

good luck on debugging this - but keep looking for a scale issue..

i have the 2 screeshot:

the original screenshot (1280*720):

http://s7.postimg.org/v9wp4cqor/screen_Temp.png

and the downscale (320*180)

as you can see, the downscaled image quality is good, so its just a renderer issue..

EDIT:

i think a need to find other way to load a image..

Using WWW is not an instant action. You either need to use "yield" to wait for the loading to be done or check www.done.

Or load by reading the file

Texture2D tex = null;

byte[] fileBinary = File.ReadAllBytes(filePath);

tex = new Texture2D(2, 2);

tex.LoadImage(fileBinary );

That is not what I ment:

AFTER you load the image from the net, the c# code that creates your RAM texture does a rescale without you knowing it!!

That is what I mean..

What probably happens is this:

- pic has 200x200 on hard drive

- pic get's loaded by your script

- pic has 25x25 in RAM

- pic has 200x200 in GUI

- result blurry display..

your code has one faulty line, that does an unwanted rescale..

look for that or you'll search forever :-)

ok sorry, i'm french so i don't understand all the things..

when i test with Sarbian code, i have the same issue :s

Philotical, can i choose the RAM resolution ?

[philotical]

This is all I know about it:

http://docs.unity3d.com/412/Documentation/ScriptReference/Texture2D.Texture2D.html

it looks as if you have a custom function named newTexture2D(320,180)

(or was that space ommitted newTexture vs. new Texture?)

my guess is, in that function newTexture, those numbers are ignored and the size of the texture is wrong..

[Zetla]

ok guy its working!

i just add the texture format to the texture2D

my code:

public static Texture2D screenTry = new Texture2D(320, 180, TextureFormat.ARGB32, false);

without texture format: with texture format:

thx very much to Philotical, and Sarbian, for give me the good way

ok sorry, i'm french so i don't understand all the things..

You should've said that before, me and Sarbian both are native french speakers
