mask bitmap

I searched for mask options and I did not found any.
Is there a solution to mask a bitmap ?

 

Drop shadows

Hi,
is there any easy way of generating drop shadows? I have many images (transparent .png images) that I need to dynamically generate shadows for (images are loaded from a server and can change in the future, so using something like Photoshop to change the images would not work!) ...

Any help would be appreciated!

 

When I try to run ABMeter.b4a it loads a blank screen. The following is the log when it loads.

I am using an Android 2.2 emulator API Level 8
I get the same results with Google APIs 2.2 API Level 8

I then have to force the App closed.

 

I'm using mMatrix.setPolyToPoly and ExDraw.drawBitmap4 to draw part of a bitmap as a trapezoid using a SRC rect. The problem is, it's drawing the entire bitmap around that SRC instead of just what's inside it. How do I change that?

I'm working around it with a path, but I'd prefer not to since you can only use 1 at a time.

 

It is possible, using your ABExtDrawing and ABCamera, to get a picture (rear camera)
and find an "object" (little bitmap) that is located in the picture obtained?

 

@LucaMs No. ABCamera has nothing to do with the physical device camera. It is a 'viewpoint' camera that affect the draw functions on a canvas.

 

Many thanks for your reply (especially because you are... alwaysbusy )

 

You aked me here to look at this subject.
Unfortunately I have no experience in this area.

 

Really "Unfortunately".

But I'm sure that if you wanted ... and if I explained to you the purpose...!

If you want, contact me "in private"

 

Can someone help me just draw picture on Canvas using this library?
I need to avoid canvas using Nearest neighbor and I need to use Bicubic resample image.
I trying without success.

Basicly i need only this but with Bicubic resample image:

Code:

Sub Globals
    Dim Canvas1 As Canvas
    Dim Logo As Bitmap
End Sub

Sub Activity_Create(FirstTime As Boolean)
    Logo.Initialize(File.DirAssets,"logo.png")
    Dim SrcRect As Rect
    SrcRect.Initialize(0,0,1080, 1920)
    Dim DestRect As Rect
    DestRect.Initialize(0,0,540, 960)
    Canvas1.Initialize(Activity)
    Canvas1.DrawBitmap(Logo,SrcRect,DestRect)
End Sub

I will be very grateful

 

Where i can find the 3D Camera Project thread ?
I want to add an background image behind the turning 3d "cubes"

 

And how can i get/identify a clicked "cube" ?

 

Hi alwaysbusy,

It's a thank you for this great library. I use it to program a speed-meter to display the speed of a car. It run on my Samsung S1 and on a Samsung tablet (10.1). But is looks very strange on a Samsung S3 phone.

Please look to this thread: http://www.basic4ppc.com/android/forum/threads/abmeter-different-look.43821/

I hope that you can help.
Regards
Hugo

 

There is an issue with drawtext on a canvas in Android 4.2.1. (maybe others). Google says you need to add the following to your paint:

ScalePaint.setLinearText(True)

Then the text will show up ok.

 

Great library!
It's possible to lock the scrolling when the picture reaches the bottom?

 

@alwaysbusy,

Thank you very much! ScalePaint.setLinearText(True) fixes the my problem. Great!

 

thank you

 

@alwaysbusy,

Is there a solution for Android 5?

 

@HugoSX2 What do you mean a solution for 5? Does it give an error? I don't have a device with 5 yet.
