Trying to quickyly get the size of an image file under windows, want to scan a list of files and get their height/width, any ideas how to do this.
Did a search found some old code using IMAGEINFO, but it no longer works, try this link.

Thanks

Hi Jose:
You can try ImageWidth() and ImageHeight() for BMP,JPG, PNG, TIFF and TGA images.
Code: Select all
UseJPEGImageDecoder()
UsePNGImageDecoder()
UseTIFFImageDecoder()
UseTGAImageDecoder()
;__________here start a loop
LoadImage(0, "c:\test.jpg") ; ********here your images**********
Debug ImageWidth()
Debug ImageHeight()
FreeImage(0)
;_________end loop
Hope this helps
Regards
Einander

Thanks einander, I figured that one out after doing some testing, but what I really wanted was a windows API way to tell the height/width of any image, I just want the info, dont need to use the image files.
Anyone know how to use API GetImageInfo() or something like it to get image file height/width.
