Detailed Description
A simple implementation of the Scale2x algorithm for scaling raw image data.
Definition at line 30 of file RawScale2x.java.
Constructor & Destructor Documentation
◆ RawScale2x()
| com.realtime.crossfire.jxclient.faces.RawScale2x.RawScale2x | ( | @NotNull final int [] | imageData, |
| final int | dataWidth, | ||
| final int | dataHeight | ||
| ) |
Creates a new scaler based on some raw data.
Right now it doesn't matter what order the channels in, just that its an int per pixel
- Parameters
-
imageData the source image data dataWidth the width of the source image dataHeight the height of the source image
Definition at line 61 of file RawScale2x.java.
Member Function Documentation
◆ different()
|
staticprivate |
Checks if two pixels are different.
Place holder for maybe some clever code about tolerance checking.
- Parameters
-
a the first pixel value b the second pixel value
- Returns
- if the pixels are differenttrue

◆ getScaledData()
| int [] com.realtime.crossfire.jxclient.faces.RawScale2x.getScaledData | ( | ) |
Gets the scale image data.
Note this is the method that does the work so it might take some time to process.
- Returns
- an array of pixels 4 times the size of the input array containing the smoothly scaled image

◆ getSourcePixel()
|
private |
Gets a pixel from the source image.
This handles bonds checks and resolves to edge pixels.
- Parameters
-
x the x location of the pixel to retrieve y the y location of the pixel to retrieve
- Returns
- the pixel value at the specified location

Referenced by com.realtime.crossfire.jxclient.faces.RawScale2x.process().
Here is the caller graph for this function:
◆ process()
|
private |
Processes a specific pixel.
This will generate 4 pixels in the destination image based on the scale2x algorithm.
- Parameters
-
x the x location in the source image of the pixel to process y the y location in the source image of the pixel to process

Here is the caller graph for this function:
◆ setDestPixel()
|

Sets a pixel in the destination image data.
- Parameters
-
x the x location of the pixel to set y the y location of the pixel to set p the value of the pixel to set
