h3{color:#8B0000}. +Creation...+

Images can either be created by type and size.

<pre><code class="ruby">

im=createImage(dataCategory.dtScalar,scalarDataType.sdtUINT8)

im.setSize(256,256)

im.allocateImage()

</code></pre>

which type and size are this following value:

    * *Type*: _sdtINT8, sdtINT16, sdtINT32, sdtINT64, sdtUINT8, sdtUINT16, sdtUINT32, sdtUINT64, sdtFloat, sdtDouble, sdtBIT, sdtOffset, sdtLabel, sdtSTR, sdtObject, sdtCompound, sdtList, sdtMap, sdtPair_.

    * *size*: _dtScalar, dtAngular, dtComplex, dtPixel3, dtPixel4, dtOffsetList, dtPointer, dtArray, dtImage, dtNeighborhood, dtVariant, dtCVariant_. 

h3{color:#8B0000}. +Load from file...+

Images can be loaded from a file, and can be write to a file

<pre><code class="ruby">

im2=pngFileRead("foo.png")

im2=bmpFileRead("foo.bmp")

im2=csvFileRead("foo.csv")

im2=jpegFileRead("foo.jpg")

pngFileWrite(im2,"foo.png")

bmpFileWrite(im2,"foo.bmp")

csvFileWrite(im2,"foo.csv")

jpegFileWrite(im2,"foo.jpg")

#generic function

im2=fileRead("foo.png")

fileWrite(im2, "foo.jpg")

</code></pre>

PNG is the best supported format.

h3{color:#8B0000}. +Features...+

Images are Python objects and as such are reference-counted and automatically destroyed when leaving the scope. This code does not leak memory:

<pre><code class="ruby">

while 1:

im=pngFileRead("hop.png")

</code></pre>

Images are passed and copied by reference:

<pre><code class="ruby">

im2=im1

ImSetConstant(im1,255)

for pixel in im2:

print pixel

</code></pre>

The second image is also put to 255. A new image can be created by using getSame and ImCopy:

<pre><code class="ruby">

im2=im1.getSame()                   #or im2=ImCreateSame(im1)

im3=im1.ImCreateSame(im1, "UINT16") #changing image type

ImCopy(im1,im2)

ImSetConstant(im1,255)

for pixel in im2:

print pixel

</code></pre>

The second image will have kept its values even while the first is uniformally set to 255.
