[Gdip] Use Base64 PNG data with Gdip? Topic is solved

[TheDewd]

i'll happily accept a pull request. i think we need some documentation within the func on how to create the base64 string to begin with (i saw a SKAN link earlier up in this thread?). or could even add a new Example file too to the lib

and i'm not sure if just a boolean param at the end is sufficient for return type. seems like TheDewd now has ways to return either HICON, hBitmap, or pBitmap. do we want all those options? i argue no. i think it should just return the pBitmap and be named "Gdip_CreatBitmapFromBase64()" for consistency. because, the lib already has the wrapper funcs to convert a pBitmap into an hBitmap or hIcon that the user can simply nest the funcs on top of each other if they need those other formats. most of the lib works with simply pBitmaps

I agree that returning only pBitmap should be sufficient, and then have separate functions to return either HICON or HBITMAP instead of having it as an all-in-one function.

I created the function to be unique to the project I was working on at the time. It makes perfect sense to keep the functions separate if the intent is to add them to the GDI+ library.

Yes, it seems that SKAN does have an example of converting images to a Base64 string. See https://autohotkey.com/boards/viewtopic ... 07#p165507

To compress images for my personal projects, I've been using Compress-Or-Die. They have an option for "extreme" compression that shortens the Base64 string even further than some of the other websites I've used in the past. I'm not suggesting to use a website in the documentation for converting an image to Base64 -- I just wanted to share the website in case anyone else might find the "extreme" compression option useful.

[dammtools]

I modified the function for a new project so that I can assign the images to a Picture control.

The previous function will return the pBitmap pointer, but I added an extra DllCall to convert pBitmap to hBitmap.

See example below:

This is awesome. Tried if I could use more images in a GUI with this and worked like a charm.
Just one question: does this removes transparency from PNG images? In my tests I overlapped two images to test it and it seems transparency is gone. Can you confirm this, please?

You will need to use +BackgroundTrans on the image to make it transparent when you do the overlapping.
