| Hiya Coders I use BlitzPlus as, among other things, a scripting utility. I make routines to create webpages ind index files - all sorts of stuff. One indispensible script is for resizing images for web content. My method for this is to show the image on screen at the size I want and then capture that screen area. I process directories of images at a time. My problem is that the resized images can only be saved by BlitzPlus as .bmp files. I need them to be .jpg files. Can anyone tell me how to save the shots as .jpg file? Thank you for your kind attention (-_-) And example script: ;~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ; ResizeByWidth.bp ;~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Global csd Global file$, bmp$ Global pic, ok, x#, d# Global sorc$, dest$ Global xres=GadgetWidth(Desktop()) Global yres=GadgetHeight(Desktop()) Graphics xres, yres,16,0 SetBuffer BackBuffer() sorc$="big/" dest$="small/" csd=ReadDir(sorc$) Repeat file$=NextFile$(csd) If Len(file$)>5 bmp$=Left$(file$,Len(file$)-3)+"bmp" pic=LoadImage(sorc$+file$) x# = ImageWidth(pic) d# = 150.0/x# ScaleImage pic, d#, d# Cls DrawImage pic, 0,0 Flip Delay 200 ok=SaveImage (pic,dest$+bmp$) FreeImage(pic) EndIf Until file$="" End |
