Here’s a graphical illustration of the difference between CENTER_INSIDE and FIT_CENTER. Image used (100 × 100): Small image view (75 × 50): CENTER_INSIDE: FIT_CENTER: Both CENTER_INSIDE and FIT_CENTER shrink the image. Large image view (300 × 200): CENTER_INSIDE: FIT_CENTER: CENTER_INSIDE does not enlarge the image, FIT_CENTER does. The Android robot is reproduced or modified from … Read more
To expand on Karan’s answer: As a general rule you won’t see any difference if you’re scaling your image down, but you will if you’re scaling it up. Passing filter = false will result in a blocky, pixellated image. Passing filter = true will give you smoother edges. However, as EIYeante pointed out in the … Read more
Let’s say you want to scale a range [min,max] to [a,b]. You’re looking for a (continuous) function that satisfies f(min) = a f(max) = b In your case, a would be 1 and b would be 30, but let’s start with something simpler and try to map [min,max] into the range [0,1]. Putting min into … Read more
You’ll have to convert it from dps to pixels using the display scale factor. final float scale = getContext().getResources().getDisplayMetrics().density; int pixels = (int) (dps * scale + 0.5f);
To specify the coordinates within the SVG image independently of the scaled size of the image, use the viewBox attribute on the SVG element to define what the bounding box of the image is in the coordinate system of the image, and use the width and height attributes to define what the width or height … Read more
