Question

我有一个图形,尺寸300*90。 h/mdpi/ldpi的尺寸如何? 增编

Answer 1

<谷歌a href=”https://developer.android.com/training/multicr/ Screendensities#TaskProvideAltBmp”rel=“nofollow noreferer”>suggests 使用

3: 4 : 6 : 8 : 12 : 16 比额表比率

ldpi : mdpi : hdpi : xhdpi :xxhdpi : xxxhdpi。例:

36x36 for low-density
48x48 for medium-density
72x72 for high-density
96x96 for extra high-density
144x144 for extra-extra-high-density
192x192 for extra-extra-extra-high-density

举例来说,如果提到纽特州的规模,那么正确的层面应当是:

150x45 ldpi
200x60 mdpi
300x90 hdpi
400x120 xhdpi
600x180 xxhdpi
800x240 xxxhdpi

Answer 2

这取决于对你设计这种图形的大小装置。如果你想在320x480(HVGA)大豆中显示300x90,那么,你的粉末尺寸对计量吸入器装置是正确的,你需要以下图像:

LDPI: 225x68px
MDPI: 300x90px
HDPI: 450x135px

LDPI是计量吸入器规模的75%,而DPHPI是计量吸入器规模的150%。例如,如果你在480x800(WVGA)水面设计了这些图象,那么,对于PPI来说,你的范围已经正确,你需要从那里缩小另外两个层次:

LDPI: 150x45px
MDPI: 200x60px
HDPI: 300x90px

Hope that Helps!

Complete Formula to create all asset folder images

首先,你们必须决定,一旦你决定并制作图像,那么,你们会根据

public class DPICalculator {

    private final float LDPI = 120;
    private final float MDPI = 160;
    private final float HDPI = 240;
    private final float XHDPI = 320;

    private final float BASE_DPI = MDPI;

    public static void main(String[] args) {
        DPICalculator cal = new DPICalculator();

        cal.calculateDPI_baseUnitPixel(300, 90, cal.HDPI);
    }

    private float densityWidth;
    private float densityHeight;

    public void calculateDPI_baseUnitPixel(float width, float height, float currentDensity) {

        densityWidth = getDensityPX(width, currentDensity);
        densityHeight = getDensityPX(height, currentDensity);

        this.calculateAllDP();
    }

    private float getDensityPX(float value, float currentDensity) {
        return (value / (currentDensity / BASE_DPI));
    }

    public void calculateDPI_baseUnitDPI(float width, float height, float currentDensity) {

        densityWidth = getDensityDPI(width, currentDensity);
        densityHeight = getDensityDPI(height, currentDensity);

        this.calculateAllDP();
    }

    private float getDensityDPI(float value, float currentDensity) {
        return (value * (currentDensity / BASE_DPI));
    }

    private void calculateAllDP() {
        // get all settings.
        float low_pw = densityWidth * (LDPI / BASE_DPI);
        float low_ph = densityHeight * (LDPI / BASE_DPI);

        float med_pw = densityWidth * (MDPI / BASE_DPI);
        float med_ph = densityHeight * (MDPI / BASE_DPI);

        float high_pw = densityWidth * (HDPI / BASE_DPI);
        float high_ph = densityHeight * (HDPI / BASE_DPI);

        float xhigh_pw = densityWidth * (XHDPI / BASE_DPI);
        float xhigh_ph = densityHeight * (XHDPI / BASE_DPI);

        System.out.println("LDPI " + low_pw + " x " + low_ph);
        System.out.println("MDPI " + med_pw + " x " + med_ph);
        System.out.println("HDPI " + high_pw + " x " + high_ph);
        System.out.println("XHDPI " + xhigh_pw + " x " + xhigh_ph);

    }
}

成果

LDPI 150.0 x 45.0
MDPI 200.0 x 60.0
HDPI 300.0 x 90.0
XHDPI 400.0 x 120.0

Answer 4

为此,你可以尝试一下我为扩大不同类型(png, jpg, gif, svg, psd, 9-TOP)图像而制作的工具。使用的是按质量计算法,支持某些无损压缩工具,如粉碎。有一个GUI和指挥线。
