Unblur rendering in javaFX (rescaling snes base resolution)

[drowsy brook]

Hello ! I'm new at programmin in java and i need help for a school project. I need to make the bases of a game, and i wanted to recreate the legend of zelda a link to the past, wich is a SNES game, with a base resolution of 256x224, so all my sprites and tiles are in this format (tile is in 16x16 and sprite in 16x24) but when i rescale it, it become blurry. Is there a solution to let the rendering still with apparent pixels ?

I can post my code if needed !

rescale smaller or bigger ?

[drowsy brook]

bigger ! about 3 or 4 time

[toxic skiff]

well yea

it will be blurry

[drowsy brook]

no possibility to keep big pixels ?

[toxic skiff]

because javafx needs to add pixels which don't exist

[toxic skiff]

hmm let me check

[drowsy brook]

okk thanks !

[vast magnet]

but wouldnt it be possible if you scale by 2x on both axis that it will not be blurry, because you could just give stuff that originally needs 1 pixel, just 2 pixel with the same color?

[toxic skiff]

try https://www.reddit.com/r/JavaFX/comments/x9rg5w/issue_with_displayed_image_looking_smoothed/

[drowsy brook]

Yeah that's what i originally thinked, but it was blurry anyway, i thought that if it was a direct multiple it would not be blurry but apparantly it still is

[drowsy brook]

Thanks, let me check !

[vast magnet]

well how are you scaling it?

[toxic skiff]

let me know if it works

[toxic skiff]

Probably by just letting javafx automatically scaling it

[drowsy brook]

yes ! I can post my code handling this if it can help !

[vast magnet]

thats guessing, also which javafx element are you using for the sprite

you using canvas?

[drowsy brook]

i am using images but if you have a better solution it would be great !

I am still new to java and it's my first project, so I am kind of following a tutorial on Youtube, and I admit i don't understand everything

[drowsy brook]

They say that if i put this line it will disable the filters, but where and how can I implement it ? GraphicsContext2D#setImageSmoothing(false)

[toxic skiff]

What are you using, a canvas ?

[vast magnet]

well thats if you use a Canvas element

so it would be helpful sharing your current setup

[drowsy brook]

Here is how i'm handling the player sprites at this time (I still have some issues) public void getPlayerImage()
{
try {
up1 = new Image("file:res/player/U1.png");
up2 = new Image("file:res/player/U2.png");
down1 = new Image("file:res/player/D1.png");
down2 = new Image("file:res/player/D2.png");
left1 = new Image("file:res/player/R1.png");
left2 = new Image("file:res/player/R2.png");
right1 = new Image("file:res/player/R1.png");
right2 = new Image("file:res/player/R2.png");
} catch (Exception e) {
e.printStackTrace();
}
}

[toxic skiff]

but how are you displaying them, are you using a canavs or not ?

[drowsy brook]

Oh yess !!

sorry

missunderstood

[vast magnet]

probably just using Pane with absolute positioning

[toxic skiff]

So you are using a canvas ?

[drowsy brook]

I am using public class GamePanel extends Canvas {

[vast magnet]

ah ok

thats basically using a canvas

[toxic skiff]

you shouldn't extend it, but ok

[drowsy brook]

Is there a way to share my code ?

[vast magnet]

just post the files here

our bot going to upload them automatically

[toxic skiff]

so just call this

[vast magnet]

for everyone to easily view

[leaden tartan]

I uploaded your attachments as Gist.

[vast magnet]

each canvas got a graphics context, you can get it using Canvas#getGraphicsContext2D

there you store it as gc variable

call the setImageSmoothing method on it

[drowsy brook]

oh yess i see it !

so i replace it with gc = GraphicsContext2D#setImageSmoothing(false); ?

[toxic skiff]

also, please don't shorten with with gc, use ctx or context, but not gc @drowsy brook

[toxic skiff]

no

you just call gc.setImageSmoothing(false)

[drowsy brook]

OHHHH THANKS A LOT

[drowsy brook]

okk, i will ! can you tell me why please ?

[toxic skiff]

because gc means garbage collector

[vast magnet]

gc is kinda a reserved abbreviation for garbage collector in the context of java/programming

[drowsy brook]

Okay ! thank you very much for your help !

I have a lot of issues in my project, i may need your help in the future haha ^^ sorry for the disturbance

[vast magnet]

all good

[drowsy brook]

I admit java is quite of complicated for me so I do not understand everything, but I hope I will someday !

Also ! I have an issue with my character sprite

[toxic skiff]

complicated compared to ?

[drowsy brook]

I'm new to object oriented programing languages I admit, i'm a first year student in computer science

[toxic skiff]

What did you do before ?

[drowsy brook]

Freepascal, python, C (C is also difficult but I was used to the logic so)

[toxic skiff]

freepascal

[drowsy brook]

It's an old programming language

[toxic skiff]

I mean

I have heard of pascal

but freepascal

Also I never tho that some school would teach pascal lol

[drowsy brook]

Yeah I know, but it's I think a way to force us to understand the algorithms and logic and try ourself without much help on internet (compared to other langages that are much more popular) i think ?

[toxic skiff]

[drowsy brook]

yeah strange i know

I have an issue with the sprites, the tiles are 16x16 pixels but the character is 16x24, so the character is strecht to the size of tile and i don't know how to fix it

I can upload the file handling it

[toxic skiff]

why not display the character 16x24 ?

[drowsy brook]

I tried but let me retry an other time
