Determine width and height of a bitmap

Image
By User



I am using the following code snippet to create a bitmap with text.







Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG); 

paint.setStyle(Style.FILL);

paint.setColor(fontColor);

paint.setTextSize(fontSize);

canvas.drawText("My Text", x, y, paint);







Here's the catch. How do I determine the size of the Bitmap to use in the canvas beforehand? For instance if I want a bitmap with "Hello World!" on it, I want to find the width and height of it even before I draw the text on the canvas.

    You can tyr this:

    Paint paint = new Paint(Paint.ANTI_ALIAS_FLAG);

    Rect bounds = new Rect();

    paint.setStyle(Style.FILL);
    paint.setColor(fontColor);
    paint.setTextSize(fontSize);

    paint.getTextBounds("My Text", 0, "My Text".length(), bounds);

    int width = bounds.width();
    int height = bounds.height();

    canvas.drawText("My Text", x, y, paint);

    Try this, it loads the bitmap, then gets the heigth and width, then you just have to draw it. Replace bitmap with your image name

    bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.bitmap);
    bitmapHeigth = bitmap.getHeigth();
    bitmapWidth = bitmap.getWidth();

Why is this Javascript much *slower* than its jQuery equivalent?

By User
I have a HTML list of about 500 items and a "filter" box above it. I started by using jQuery to filter the list when I typed a letter (timing code added later): $('#filter').keyup( function() { var jqStart = (new Date).getTime(); var search = $(this).val().toLowerCase(); var $list = $('ul.ablist > li'); $list.each( function() { if ( $(this).text().toLowerCase().indexOf(search) === -1 ) $(this).hide(); else $(this).show(); } ); console.log('Time: ' + ((new Date).getTime() - jqStart)); } ); However, there was a couple of seconds delay after typing each letter (particularly the first letter). So I thought it may be slightly quicker if I used plain Javascript (I read recently that jQuery's each function is particularly slow). Here's my JS equivalent: document.getElementById('filter').addEventListener( 'keyup', function () { var jsStart = (new Date).getTime()...

Is it possible to have IF statement in an Echo statement in PHP

By User
Thanks in advance. I did look at the other questions/answers that were similar and didn't find exactly what I was looking for. I'm trying to do this, am I on the right path? echo " <div id='tabs-".$match."'> <textarea id='".$match."' name='".$match."'>". if ($COLUMN_NAME === $match) { echo $FIELD_WITH_COLUMN_NAME; } else { } ."</textarea> <script type='text/javascript'> CKEDITOR.replace( '".$match."' ); </script> </div>"; I am getting the following error message in the browser: Parse error: syntax error, unexpected T_IF Please let me know if this is the right way to go about nesting an IF statement inside an echo. Thank you.
