Examples with TextureFilter com.badlogic.gdx.graphics.Texture.TextureFilter used on opensource projects

Example 1 with TextureFilter

use of com.badlogic.gdx.graphics.Texture.TextureFilter in project libgdx by libgdx.

the class BitmapFontDistanceFieldTest method drawFont.

private int drawFont(BitmapFont font, String description, boolean linearFiltering, boolean useShader, float smoothing, int x) {
    int y = 10;
    float maxWidth = 0;
    spriteBatch.setShader(null);
    descriptionFont.draw(spriteBatch, description, x, y);
    spriteBatch.flush();
    y += 10 + 2 * descriptionFont.getLineHeight();
    // set filters for each page
    TextureFilter minFilter = linearFiltering ? TextureFilter.MipMapLinearNearest : TextureFilter.Nearest;
    TextureFilter magFilter = linearFiltering ? TextureFilter.Linear : TextureFilter.Nearest;
    for (int i = 0; i < font.getRegions().size; i++) {
        font.getRegion(i).getTexture().setFilter(minFilter, magFilter);
    }
    if (useShader) {
        spriteBatch.setShader(distanceFieldShader);
    } else {
        spriteBatch.setShader(null);
    }
    for (float scale : SCALES) {
        font.getData().setScale(scale);
        layout.setText(font, TEXT);
        maxWidth = Math.max(maxWidth, layout.width);
        if (useShader) {
            distanceFieldShader.setSmoothing(smoothing / scale);
        }
        font.draw(spriteBatch, layout, x, y);
        y += font.getLineHeight();
        spriteBatch.flush();
    }
    return (int) Math.ceil(maxWidth);
}

Example 2 with TextureFilter

use of com.badlogic.gdx.graphics.Texture.TextureFilter in project libgdx by libgdx.

the class MipMapTest method createUI.

private void createUI() {
    skin = new Skin(Gdx.files.internal("data/uiskin.json"));
    ui = new Stage();
    String[] filters = new String[TextureFilter.values().length];
    int idx = 0;
    for (TextureFilter filter : TextureFilter.values()) {
        filters[idx++] = filter.toString();
    }
    hwMipMap = new CheckBox("Hardware Mips", skin);
    minFilter = new SelectBox(skin);
    minFilter.setItems(filters);
    magFilter = new SelectBox(skin.get(SelectBoxStyle.class));
    magFilter.setItems("Nearest", "Linear");
    Table table = new Table();
    table.setSize(ui.getWidth(), 30);
    table.setY(ui.getHeight() - 30);
    table.add(hwMipMap).spaceRight(5);
    table.add(new Label("Min Filter", skin)).spaceRight(5);
    table.add(minFilter).spaceRight(5);
    table.add(new Label("Mag Filter", skin)).spaceRight(5);
    table.add(magFilter);
    ui.addActor(table);
}
