B4J Question Avoid the knurling when import image into label programatically

Nuno Durães

Hello everybody,

I imported an image in the designer into a label. The image was built from SVG and exported to PNG. For some reason, the result is not being the best, because for no apparent reason the image appears jagged.

Actually I need to programmatically import it, but I can't understand the correct way to do it.
Are there any directives to avoid the knurling ? How do I do that
Thanks in advance

If you export an SVG as an png the resulting image should have 100% precision/Quality.
Exporting it as 1024x1024 Image will result in an 1024x1024 Image with 100% precision/Quality.

So the real question is:
In what size you did exported the SVG?
In what size you are USING the png in your app?

Hi DonManfred,

The SVG edition is 3038,934 X 3022,373 px. I added printscreens of this edition, the properties in the designer and the frame of the app.

Tried to load programatically. The result is better but still not good.
The printscreen is attached.
B4X: 
'Icons
            Dim IconImage As Image = xui.LoadBitmapResize(File.DirAssets, baseIcon(i) ,100 * imv_BaseIcon.Width / 100,100 * imv_BaseIcon.Height / 100, True)
      '     Dim IconImage As B4XBitmap = xui.LoadBitmap(File.DirAssets, baseIcon(i))
            imv_BaseIcon.SetImage(IconImage)
