Ok here is a negative h BMP

W = 1024
H = -831

It says 831 at the bottom of the image, but that is an ABS value

@NOVARSEG

Thanks I am convinced just changing H to Long Type is not enough. But we knew that, I guess, I did after I went and reread everything again. Steve never updated his fixed Sub with another?

I checked back to last version you posted, it may work but it isn't in a handy, portable and convenient Sub like I have here. So get to work man! ;-))

Sorry, the Interpreter muse has struck me again (won't Aurel be thrilled?) or I'd be fixing myself.

This pipecom code and array displayer are some new features planned for making editable code as well as retrieving files.
I have found my way to a "No double quotes for strings" theory, just bare naked text.

PS might need a Line Editor, not a full fledged WP.

Been awhile since I wrote a SUB

Do I have to put my DIMS inside the sub? I like my DIMS at the start of a program.

Are the global, or local variables?

DIM inside a sub keeps the values local to the sub, whereas DIM SHARED in the main module makethem global.

NOVARSEG · « **Reply #19 on:** February 09, 2021, 09:37:24 pm »

OK the sub would have to be something like

SUB loadBMP24 (Filename as string$, W AS LONG, H AS LONG, HANDLE AS LONG)
retunrs W width of BMP
returns H height of BMP
returns handle generated from " HANDLE = _NEWIMAGE(W, ABS(H), 32) "
input Filename
****

Gettimg a "memory not initialized" these lines of code are inside the sub

SCREEN _NEWIMAGE(W, (ABS(H)), 32)
_PUTIMAGE (0, 0), HANDLE
_MEMFREE a

the _MEMFREE a is throwing the error

*******
later DIM SHARED a AS _MEM

fixed that error

@NOVARSEG

Once you get image loaded under handle you should be able to just pass handle back to main code through a Function that has type Long & on end of it's name.

I've got you started in BMP thread.

NOVARSEG · « **Reply #21 on:** February 09, 2021, 10:06:30 pm »

I have a SUB working

SUB loadBMP24 (FILENAME AS STRING, W AS LONG, H AS LONG, HANDLE AS LONG)

returns W width of BMP
returns H height of BMP
returns handle generated from " HANDLE = _NEWIMAGE(W, ABS(H), 32) "
input Filename

the SUB does not display any image. That has to be done outside the SUB

Over to the other thread

Since you guys are almost done reinventing the wheel (24-bit BMP loader in this case), I’d like to also refer you to the wiki: https://www.qb64.org/wiki/Bitmaps

With it as a reference, you can expand and load 1, 4, 8 bit BMP files too, next. :)

Ho Ho. It is to laugh... lol

I was replying and hit ENTER before I had finished... Doh!

BPlus,

The commands 'ls' and 'dir' will display current directory contents. Main difference... the 'ls' command will display directories, executables and files in different colours. 'dir' is only white. Adding '-l' to the command will give a detailed list. To easily distinguish folders, commands and files, 'ls' or ls -l' would be the best.

There is probably a better way to do this but these are the commands that "I" use....
