You just need UsePNGImageEncoder() and UsePNGImageDecoder() to use PNG, why do you want to add the zip lib ? The zip lib large because it use libarchive which handle a lot of file format. But if you use both, it uses a common libzip defalte as both need it, that's why 36KB are saved.



it ...

it is clear that has 303 - 148 = 155 KB more ?

Am I wrong or does your math looks a little wonky?

I see 303 KB - (148 KB - 5 KB) - (201 KB - 5 KB) = -36 KB. So combining everything into the exe sized 303 KB seems to save 36 KB.


so you mean the PNG format placeholder without the deflate ...

In PB 5.72 x86, compiled to final exe size :



MessageRequester("","")

exe = 5 KB

MessageRequester("","")

exe = 148 KB

Zlib provides functions like deflate (compress) and inflate (decompress)

ZIP files often use deflate compression internally to compress individual files

I come from a language background where case statements can support multiple variables and conditional tests, which I miss, but we have If/ElseIf.

Do you have an example of what you would like to do but can't?


begin case

.. do something

case ...

i was avoiding SELECT - CASE most the time , use IF-THEN -ELSE make more fun

PB 6.20 allows library creation
but for the moment, managing optional procedure parameters is a bit tricky.
to remedy this problem I've made a little code

There is no point in getting upset about it now. Other IDEs do the same thing. In VSCode, the concept is called LanguageServer. There is also a dedicated process running in the background that collects information about how the IDE should highlight the syntax.


i am not upset , but used to it ...
