PNG filmstrip cropping (Delphi 2010)

I have a png image filmstrip as follows: filmstrip

I would like to know how to crop each image and put these images in the TImageList control, always preserving transparency.

[EDIT]

Yes, during development, the trick mentioned by RRUZ works fine, but I wanted to crop the images at runtime, i.e. loading a filmstrip from a resource or file

You must follow these steps:

  • set the property ColorDepthvalue cd32Bit,

  • DrawingStyleto dsTransparent,

  • Height= 48,

  • Width= 48,

then upload the image and the result will be

If you want to save your data in PNG format, you should not use the VCL TImageList to store it, because you will need to do the conversion from PNG to TBitmap in order to actually use the TImageList.
