Memory error

Posted: Thu Oct 10, 2024 10:10 AM

I'm trying to glue 2 bitmap files and save them to a files:

map1.jpg - https://cloud.mail.ru/public/yDjE/jFfNgNw7s
map2.jpg - https://cloud.mail.ru/public/UpXQ/CxwNAb4Nc

Code (fw): Select all Collapse

hBmp:=FW_StitchImages(path+"\map1.jpg", path+"\map2.jpg", "B")
FW_SaveImage(hBmp, path+"\map.jpg")

When writing to a file, I get a memory error: hb_xgrab can't allocate memory

How to solve this problem ?

Do the same test with 2 smaller .jpg files, to make sure it's not the size of the images that blows up the memory.

Haga la misma prueba con 2 archivos .jpg más pequeños, para asegurarse de que no sea el tamaño de las imágenes lo que explote la memoria.

Why do I need a link to my topic ?

There I tried to glue 2 files with a size of about 12 mG and broke down from memory.

Now I have learned how to compress jpg files by about 9 times (up to 1.5 mG), but I get the same error

Can I see a little but still compilable and runnable sample showing the problem (with the 2 images), please?

I could see the images but could not download them.
It appeared to me that the size of each image is very huge and both together may not be fitting in the memory.
Then this should probably work with 64 bits application.

Mr. Natter
Can you please provide this information for each jpg?

Code (fw): Select all Collapse

aImage := FW_ReadImage( nil, cJpeg )
? aImage[3], aImage[4]   // width, height
PalBmpFree( aImage )

Also, size of the file on disk in bytes
