For a more accurate conversion, first use filter(GRAY)
|
||
|
|
which will make the image into a "correct" grayscake by
|
||
|
|
performing a proper luminance-based conversion.

<DD>Blend two colors based on a particular mode.
|

|
|
<UL>
|
||
|
|
<LI>REPLACE - destination colour equals colour of source pixel: C = A.
|
||
|
|
Sometimes called "Normal" or "Copy" in other software.
|
||
|
|
|
||
|
|
<LI>BLEND - linear interpolation of colours:
|
||
|
|
<TT>C = A*factor + B</TT>
|
||
|
|
|
||
|
|
<LI>ADD - additive blending with white clip:
|
||
|
|
<TT>C = min(A*factor + B, 255)</TT>.
|
||
|
|
Clipped to 0..255, Photoshop calls this "Linear Burn",
|
||
|
|
and Director calls it "Add Pin".
|
||
|
|
|
||
|
|
<LI>SUBTRACT - substractive blend with black clip:
|
||
|
|
<TT>C = max(B - A*factor, 0)</TT>.
|
||
|
|
Clipped to 0..255, Photoshop calls this "Linear Dodge",
|
||
|
|
and Director calls it "Subtract Pin".
|
||
|
|
|
||
|
|
<LI>DARKEST - only the darkest colour succeeds:
|
||
|
|
<TT>C = min(A*factor, B)</TT>.
|
||
|
|
Illustrator calls this "Darken".
|
||
|
|
|
||
|
|
<LI>LIGHTEST - only the lightest colour succeeds:
|
||
|
|
<TT>C = max(A*factor, B)</TT>.
|
||
|
|
Illustrator calls this "Lighten".
|
||
|
|
|
||
|
|
<LI>DIFFERENCE - subtract colors from underlying image.
|
||
|
|
|
||
|
|
<LI>EXCLUSION - similar to DIFFERENCE, but less extreme.
|
||
|
|
|
||
|
|
<LI>MULTIPLY - Multiply the colors, result will always be darker.
|
||
|
|
|
||
|
|
<LI>SCREEN - Opposite multiply, uses inverse values of the colors.
|
||
|
|
|
||
|
|
<LI>OVERLAY - A mix of MULTIPLY and SCREEN. Multiplies dark values,
|
||
|
|
and screens light values.
|
||
|
|
|
||
|
|
<LI>HARD_LIGHT - SCREEN when greater than 50% gray, MULTIPLY when lower.
|
||
|
|
|
||
|
|
<LI>SOFT_LIGHT - Mix of DARKEST and LIGHTEST.
|
||
|
|
Works like OVERLAY, but not as harsh.
|
||
|
|
|
||
|
|
<LI>DODGE - Lightens light tones and increases contrast, ignores darks.
|
||
|
|
Called "Color Dodge" in Illustrator and Photoshop.
|
||
|
|
|
||
|
|
<LI>BURN - Darker areas are applied, increasing contrast, ignores lights.
|
||
|
|
Called "Color Burn" in Illustrator and Photoshop.

<P>A useful reference for blending modes and their algorithms can be
|
||
|
|
found in the <A HREF="http://www.w3.org/TR/SVG12/rendering.html">SVG</A>
|
||
|
|
specification.</P>
|
||
|
|
<P>It is important to note that Processing uses "fast" code, not
|
||
|
|
necessarily "correct" code. No biggie, most software does. A nitpicker
|
||
|
|
can find numerous "off by 1 division" problems in the blend code where
|
||
|
|
<TT>>>8</TT> or <TT>>>7</TT> is used when strictly speaking
|
||
|
|
<TT>/255.0</T> or <TT>/127.0</TT> should have been used.</P>
|
||
|
|
<P>For instance, exclusion (not intended for real-time use) reads
|
||
|
|
<TT>r1 + r2 - ((2 * r1 * r2) / 255)</TT> because <TT>255 == 1.0</TT>
|
||
|
|
not <TT>256 == 1.0</TT>. In other words, <TT>(255*255)>>8</TT> is not
|
||
|
|
the same as <TT>(255*255)/255</TT>. But for real-time use the shifts
|
||
|
|
are preferrable, and the difference is insignificant for applications
|
||
|
|
built with Processing.</P>

<p>
|

|
|
As of revision 0100, this function requires an absolute path,
|
||
|
|
in order to avoid confusion. To save inside the sketch folder,
|
||
|
|
use the function savePath() from PApplet, or use saveFrame() instead.
|
||
|
|
As of revision 0116, savePath() is not needed if this object has been
|
||
|
|
created (as recommended) via createImage() or createGraphics() or
|
||
|
|
one of its neighbors.
|
||
|
|
<p>
|
||
|
|
As of revision 0115, when using Java 1.4 and later, you can write
|
||
|
|
to several formats besides tga and tiff. If Java 1.4 is installed
|
||
|
|
and the extension used is supported (usually png, jpg, jpeg, bmp,
|
||
|
|
and tiff), then those methods will be used to write the image.
|
||
|
|
To get a list of the supported formats for writing, use: <BR>
|
||
|
|
<TT>println(javax.imageio.ImageIO.getReaderFormatNames())</TT>
|
||
|
|
<p>
|
||
|
|
To use the original built-in image writers, use .tga or .tif as the
|
||
|
|
extension, or don't include an extension. When no extension is used,
|
||
|
|
the extension .tif will be added to the file name.
|
||
|
|
<p>
|
||
|
|
The ImageIO API claims to support wbmp files, however they probably
|
||
|
|
require a black and white image. Basic testing produced a zero-length
|
||
|
|
file with no error.
