| ImageData | | final class ImageData implements AbstractImageData(Code) | | AbstractImageData implementation based
on putpixel graphics library and stores data on Java heap.
|
| Constructor Summary | |
| | ImageData()
Constructs empty ImageData . | | | ImageData(int width, int height, boolean isMutable, boolean clearPixelData, boolean allocateAlpha)
Constructs ImageData using passed in width and height. | | | ImageData(int width, int height, boolean isMutable, byte[] pixelData)
Constructs mutable or immutable ImageData
using passed in width, height and pixel data. |
| Method Summary | |
| public int | getHeight()
Gets the height of the image in pixels. | | byte[] | getPixelData()
Gets pixel data associated with this ImageData instance. | | public int | getWidth()
Gets the width of the image in pixels. | | public boolean | hasAlpha()
Returns true if ImageData contains alpha data. | | void | initImageData(int width, int height, boolean isMutable, boolean allocateAlpha)
Initializes mutable or immutable ImageData
using passed in width, height. | | public boolean | isMutable()
Check if this image is mutable. | | public void | removeAlpha()
|
| ImageData | | ImageData()(Code) | | Constructs empty ImageData .
|
| ImageData | | ImageData(int width, int height, boolean isMutable, boolean clearPixelData, boolean allocateAlpha)(Code) | | Constructs ImageData using passed in width and height.
Alpha array is allocated if allocateAlpha is true.
Parameters:
width - The width of the ImageData to be created.
Parameters:
height - The height of the ImageData to be created.
Parameters:
isMutable - true to create mutable ImageData,false to create immutable ImageData
Parameters:
clearPixelData - if true pixel data whould be set to 0xff foreach pixel
Parameters:
allocateAlpha - true if alpha data should be allocated,false - if not. |
| ImageData | | ImageData(int width, int height, boolean isMutable, byte[] pixelData)(Code) | | Constructs mutable or immutable ImageData
using passed in width, height and pixel data.
Parameters:
width - The width of the ImageData to be created.
Parameters:
height - The height of the ImageData to be created.
Parameters:
isMutable - true to create mutable ImageData,false to create immutable ImageData
Parameters:
pixelData - byte array that contains pixel data for the ImageData. |
| getHeight | | public int getHeight()(Code) | | Gets the height of the image in pixels. The value returned
must reflect the actual height of the image when rendered.
height of the image |
| getPixelData | | byte[] getPixelData()(Code) | | Gets pixel data associated with this ImageData instance.
byte arra that represents pixel data associated with thisImageData instance. |
| getWidth | | public int getWidth()(Code) | | Gets the width of the image in pixels. The value returned
must reflect the actual width of the image when rendered.
width of the image |
| hasAlpha | | public boolean hasAlpha()(Code) | | Returns true if ImageData contains alpha data.
true if ImageData contains alpha data. |
| initImageData | | void initImageData(int width, int height, boolean isMutable, boolean allocateAlpha)(Code) | | Initializes mutable or immutable ImageData
using passed in width, height.
Alpha array is allocated if allocateAlpha is true.
Parameters:
width - The width of the ImageData to be created.
Parameters:
height - The height of the ImageData to be created.
Parameters:
isMutable - true to create mutable ImageData,false to create immutable ImageData
Parameters:
allocateAlpha - true if alpha data should be allocated,false - if not. |
| isMutable | | public boolean isMutable()(Code) | | Check if this image is mutable. Mutable images can be modified by
rendering to them through a Graphics object
obtained from the
getGraphics() method of this object.
true if the image is mutable,false otherwise |
| removeAlpha | | public void removeAlpha()(Code) | | Removes alpha data information
