dc.drawBitmap2

I've been trying to figure out how to use the optional parameters in this function. I use it witout worries tintcolor, but I couldn't use bitmapX bitmapY to try to select part of the image to draw.

Can anyone show me a working call to this function using these parameters? Documentation is extremely brief at this point.

Thanks in advance

I just did a test for drawBitmap2

Resources Drawables

<bitmap id="heart30" automaticPalette="false" filename="Herz30t.png" scaleX="30" scaleY="26" />…

posting your code might help

It's no about my code. Everything I try produces a runtime error, except with 0s on bitmapX and bitmapY.

Documentation isn't really helping, but I guess I can have a big image and draw it starting in different positions using these parameters, but I don't really know how it works.

Can you explain the meaning and use of these?

View.mc Initialize

myHeart30 = WatchUi.loadResource(Rez.Drawables.heart30);

View onUpdate

        // draw full heart:
        dc.drawBitmap(200, 30, myHeart30);

        if ( Graphics.Dc has :drawBitmap2 ) {       // works only for "modern" devices
            // draw part of heart:    
            dc.drawBitmap2(200, 70, myHeart30, {
                :bitmapX => 7,
                :bitmapY => 2,
                :bitmapWidth => 15,
                :bitmapHeight => 23,
            } );
        }

That works fine in simulator for Edge 1040.

Ok. Will try to mimic your example.

I'm not using scaleX, scaleY on my bitmap declaration. It doesn't make sense, but in programming every detail can make a difference!

Thanks. Will comment if it works

...for you...

Works also without scaling!

(My example is part of a datafield where I adapted the size of heart to fit better into the layout)
