Question
Crop BMP Image With VB
Hi,
I've created an application to save a picture from a webcam as a BMP, but this image is saved at 320x240 pixels.
What i would like to do is after saving this image, have vb open it up in a non visible picture box if need be, and save then crop 64pixels off the right & left of the image... giving the centre of the image. I'm certain this can be done, I just need some examples or someone to point me in the right direction as i'm in that lost puppy stage at the moment!
The final dimentions of the image need to be: 192 x 240
After the image has been cropped, i'd like it to be saved as a JPG file.
This is a quick example of what i mean (if what i wrote didnt make sense)...
==========================
= 64 = 194 = 64 =
= 64 = 194 = 64 =
= 64 = 194 = 64 =
= 64 = 194 = 64 =
= 64 = 194 = 64 =
= 64 = 194 = 64 =
= 64 = 194 = 64 =
= 64 = 194 = 64 =
= 64 = 194 = 64 =
= 64 = 194 = 64 =
= 64 = 194 = 64 =
==========================
so in effect all i want in the centre of the image... 64 pixels taken off the right & left then saved as a JPG.
If anyone can help i'd be so so so greatful!!

well the problem still stands - i can capture the image via an ocx control... then make this control save the bmp... but it saves as 320 x 240... where as i want it to save as 192 x 240 - the next problem comes as i want the file saved as a JPG file rather than a BMP file... its a tough one, and all the help is welcome.
I've asked others on EE what they thought and one guy got back to me saying that i should look into the Kodak edit control (it comes with vb6) as this should allow me to do what i want if i read the file in after saving it and then did the edit and somehow saved it... but he wasnt too sure.
The ocx control i am using is to capture from webcams etc and is available for free download from: http://www.shrinkwrapvb.co
Thanks in advance for any help you can offer :)
