PETRONODE - SlideComposer-12

Python examples

Use either Python 2.7 or Python 3.x

These examples demonstrate how the SlideComposer features can be invoked with Python. The Python code is compliant with Techlog Python module and does not require installation of extra Python libraries within the Techlog program folder (which could be risky).

Making a Basic Plot

Download code.

    Params += [ workfolder]
    Params += [ workfolder]
    Params += [ "/s"]

    f.close()

    subprocess.call( Params)
    print( "Image Processing Completed")

Name = input ( "What is your name? ")
lines = []
lines += ["#"]
lines += ["#  Create test image"]
lines += ["#"]
lines += ["slide (Test, 300, 200, png)"]
lines += ["shape (10, 10, 280, 120, rectangle, 3.0, FF000000, FFAA0000)"]
lines += ["labelover ( 20, 20, 260, 30)"]
lines += ["\tText =Hello, " + Name + "!" ]
lines += ["\tFontSize = 12.0"]

Create_Plot( ".", "Example_09", lines)
os.startfile( "Test_image.png")

If you enter 'Mike' for the name, the produced image will look like this:

Determining Image Properties

Download code.

#
# Checking the image properties
#
import os
import subprocess

#
# location of Petronode install folder
#
cBatchProcessorFolder = "C:\\Program Files\\Petronode"

#
# gets image properties
#
def Get_Image_Property ( workfolder, input, property="Y"):
    Params = [os.path.join( cBatchProcessorFolder, "Petronode.CheckImage.exe")]
    Params += [ os.path.join( workfolder, input)]
    Params += [ "/" + property.upper()]
    return subprocess.call( Params)

label = "The file is "
label += str( Get_Image_Property( ".", "Test.png", "X")) + "x"
label += str( Get_Image_Property( ".", "Test.png", "Y")) + " pixels, " 
label += str( Get_Image_Property( ".", "Test.png", "S")) + " bytes."

print (label)

The source image is like this:

The example replies:

The file is 200x300 pixels, 2442 bytes.
