Bitmap

An object that holds a bitmap image. The bitmap tin be loaded from a file or other input stream, or can exist gear up from a different bitmap.
Loading large bitmaps tin can easily lead to out of retentivity exceptions. This is true even if the file is compressed and not large equally the bitmap is stored uncompressed in retention.
For large images yous tin call InitializeSample and load a subsample of the prototype. The whole image will be loaded with a lower resolution.

Members clarification:

Crop (Left As Int, Top As Int, Width As Int, Height Every bit Int) As Bitmap

Returns a new cropped bitmap.

GetPixel (x As Int, y As Int) As Int

Returns the colour of the pixel at the specified position.

Quality - Value between 0 (smaller size, lower quality) to 100 (larger size, higher quality),
which is a hint for the compressor for the required quality.
Format - JPEG or PNG.

Example:
Dim Out As OutputStream
Out = File.OpenOutput(File.DirRootExternal, "Exam.png", False)
Bitmap1.WriteToStream(out, 100, "PNG")
Out.Close

BitmapDrawable

Sail

A Canvas is an object that draws on other views or (mutable) bitmaps.
When the canvas is initialized and set to depict on a view, a new mutable bitmap is created for that view groundwork, the current view'southward background
is copied to the new bitmap and the sail is set to describe on the new bitmap.
The canvas drawings are non immediately updated on the screen. You should call the target view Invalidate method to make it refresh the view.
This is useful every bit information technology allows you to brand several drawings and merely and so refresh the display.
The canvas tin be temporary express to a specific region (and thus only touch this region). This is done by calling ClipPath. Removing the clipping is done by calling RemoveClip.
You can get the bitmap that the sheet draws on with the Bitmap belongings.
This is an 'Activity Object', it cannot be declared under Sub Process_Globals.
