Demo Image Resize and Base64 Encode
A quick little utility that will resize an image and also Base64 Encode it.
This demo has been released to PyPI as the commnand `psgresizer`. It is also in in this repo:
https://github.com/PySimpleGUI/psgresizer
A quick little utility that will resize an image, convert between formats, and also Base64 Encode it.
Base64 is particularly good to use to make icons or other images that you include in your sourcecode.
Use this Demo to help you code your PySimpleGUI programs. Here's how:
1. Resize your image
2. Paste the base64 encoded byte-string into your code as a variable
1. Select PNG as the output format
2. Set "Encode to Base64" checkbox to True
2. Click resize button
2. Paste the base64 encoded byte-string left on the clipboard into your code as a variable
3. Use your variable for things like an icon, an image for buttons, etc.

Change log
1.3.1 16-Nov-2021
Added correct readme to PyPI
1.3.0 16-Nov-2021
Fixed bug - MUST always include the icon in the main function for these psg commands
1.2.0 16-Nov-2021
Somewhat extensive reworking of the functionality
Added a drop-down list of formats to convert to
Automatically save all the settings
And more I'm sure!
