.NET Forum / .NET Framework / Compact Framework / April 2006Saving bitmaps in CF: Reducing size in Kb
Hello, ive been looking around the net for ages just to find easy to implemen code to reduce the size of my bitmap drawing. I am making a bitmap an capture a signature onto that bitmap. Then i want to save it. Tha works but the file is too large (80kb) to send over gprs (it will b used frequently). First i looked for a way to save it as JPEG, but found nothing decent. Second i tried to save it as monochrome bitmap (only two colors ar needed). Third: Maybe compression techniques like zip? Nothing worked! Does anyone have any experience with this? Th -- jove I zip mine using the ZIP library from Resco, I also use their signature control :-) 80k doesn't seem overly large...well, not to me. Have you tried compression? I've had pretty good results in the past when compressing bitmaps. Tim Wallace > Hello, > [quoted text clipped - 10 lines] > Does anyone have any experience with this? > Thx I just found a solution! I zip the images with the SHARPZIPLIB (free) to about 1.5 KB! Then i send that as a filestream to my webservice, that unzips it an puts it in the GIF format (works on the normal .net framework, not o cf). So thats it!
