cPicture

The script plugins for batch files and powershell files are consolidated into one script plugin, which also adds python script files.
The new plugin is available from the plugins option in cPicture.
Note: The old plugins are still valid, but should be removed as they cause duplicate entries (delete cpp_bat_script.dll and cpp_ps1_script.dll in the plugins folder).

    Example PowerShell script to print the picture data

.NOTES
    This example is using the default cPicture custom data template
    for the $picture_data.cdata value.
    This value can be changed in the Settings (F9).

The new JPEG9 features:

Lossless compressed JPEGs

All lossless compressed JPEGs are displayed with an icon:

Any supported file format can be saved as a JPEG9 with lossless compression:

JPEG lossless compressed pictures can be easily sorted:

The lossless compression is an additional property of the standard JPEG format. With this setting, any standard JPEG can be saved as lossless compressed JPEG9:

Copy&Paste Bitmaps in the clip board as JPEG9:

Block scaling

Resizing supports high quality JPEG block scaling from 12.5% to 200%:

The zoomed image is a block scaled JPEG indicated by a 'JPEG' icon:

Crop&Rotate

Lossless crop with automatic alignment to the block gird:

Lossless crop for panoramic pictures or any other segmentation:

Lossless Rotate, Mirror and Transverse//Transpose (mirror on the diagonal):

What is this feature? Since the early days of image processing, pictures get scaled. They get resized to send as EMail, resized to get ready for print or resized to make a nice background image on the desktop. But most Software make a wrong assumtion about the luminosity of the pixel data. With the data interpolation you get egdes that are too dark between areas of different colors.

You picture will look more natural when resized with the gamma correction applied. cPicture has it.

Resize this image to 50% with your Software:

Do you get this?

Then your software doesn't scale correctly.
With cPicture, you get the correct scaling using 32bit/color-channel with gamma correction:

To make adjustments for all exif fields in your pictures, you can use the script plugin in cPicture to run the ExifTools on your picture selection. Assume the camera date/time is wrong by accident and all pictures are stamped with one week in advance.
This example sets all exif date fields back 7 days.
Create a text file, copy the following content and name it to ExifDate.ps1 and save it in the cPicture.exe folder:

# plugin variables

# console=true displays a console, use this option for scripts with text output
#[console=true]

# noexit=true keeps the console open, set to 'false' to have the console closed when processing is done
#[noexit=false]

Start cpicture, select your pictures you want to change, select the function module selection and select the script you just created:

Hint: If you use any of the exif functions in cPicture, ExifTools gets automatically installed for you.
