Constructor & Destructor Documentation

◆ RawScale2x()

com.realtime.crossfire.jxclient.faces.RawScale2x.RawScale2x ( final int @NotNull[]  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 have, just that it's an int per pixel

Parameters
imageDatathe source image data
dataWidththe width of the source image
dataHeightthe height of the source image

Member Function Documentation

◆ different()

static boolean com.realtime.crossfire.jxclient.faces.RawScale2x.different ( final int  a,
final int  b 
)
staticprivate

Checks if two pixels are different.

Placeholder for maybe some clever code about tolerance checking.

Parameters
athe first pixel value
bthe second pixel value
Returns
true
if the pixels are different

◆ 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()

int com.realtime.crossfire.jxclient.faces.RawScale2x.getSourcePixel ( final int  x,
final int  y 
)
private

Gets a pixel from the source image.

This handles bonds checks and resolves to edge pixels.

Parameters
xthe x location of the pixel to retrieve
ythe y location of the pixel to retrieve
Returns
the pixel value at the specified location

◆ process()

void com.realtime.crossfire.jxclient.faces.RawScale2x.process ( final int  x,
final int  y 
)
private

Processes a specific pixel.

This will generate 4 pixels in the destination image based on the scale2x algorithm.

Parameters
xthe x location in the source image of the pixel to process
ythe y location in the source image of the pixel to process

Sets a pixel in the destination image data.

Parameters
xthe x location of the pixel to set
ythe y location of the pixel to set
pthe value of the pixel to set
