Question about load pictures - Jim_001 - 10-21-2025
Hello. I'm working on a program that requires a lot of pictures. I know the pictures must be in a folder for QB64 to access them.
But is there a way to have the pictures in a file instead of a folder so QB64 can extract them from there? For example, have the pictures in a zip file and load them with
Screen _LoadImage("pictures.zip/picture1.jpg")

You just need to create the file format. LOADIMAGE supports loading from memory now, so you might be able to just write a bunch of images to a single file along with any relevant data to know where one ends and the next begins. Then you can load each image into a STRING which can be loaded with _LOADIMAGE

Zip and other similar archive formats are not natively supported. You could write a wrapper around something like PhysicsFS which then loads the file to a STRING buffer and use the memory load feature like Gets explained above.
If you are using a custom archive format with no compression and know the file offset and size, then you could simply do:
Code: (Select All)
FUNCTION LoadEmbeddedImage& (archiveFileHandle AS LONG, embeddedFileOffset AS LONG, embeddedFileSize AS LONG)
IF embeddedFileSize > 0 _ANDALSO embeddedFileOffset > 0 THEN
IF LOF(archiveFileHandle) < embeddedFileOffset + embeddedFileSize THEN
EXIT FUNCTION
END IF
DIM buffer AS STRING: buffer = SPACE$(embeddedFileSize)
SEEK #archiveFileHandle, embeddedFileOffset
GET #archiveFileHandle, , buffer
LoadEmbeddedImage = _LOADIMAGE(buffer, 32, "memory")
END IF

Thank you both for your response.
