This works fine !!<br />
<br />
But if I use a PNG with textual content, cropping result is not with that text content.<br />
Why is that?<br />
<br />
Also, how can I apply trim after cropping image?

I have a CImage object that I need to extract a portion of the image to a new CImage.<br />
I have been having trouble doing this, I saw another similar post, but there was not specific code for the solution, I am not an MFC BitBlt expert, so I really need a few lines of example code.<br />
What I am trying to do is the following:<br />
<br />
CImage imgOriginal;<br />
CImage imgCrop;<br />
<br />
imgOriginal = LoadFromResource(AfxGetIns<wbr />tanceHandl<wbr />e(),BMP_ID<wbr />); &nbsp;//THIS WORKS FINE<br />
imgCrop = LoadFromResource(AfxGetIns<wbr />tanceHandl<wbr />e(),BMP_ID<wbr />); &nbsp;// I do this just to initialize imgCrop with a valid bitmap, although it is not currently the correct bitmap<br />
<br />
HDC hdcCrop = imgCrop.getDC();<br />
imgCrop = &nbsp;imgOriginal.BitBlt(hdcCrop<wbr />,50,50,SCR<wbr />COPY);<br />
imgCrop.releaseDC();<br />
<br />
//I need imageCrop to contain a subset or in this case a shifted version of the original image, but I cant get it to work<br />
<br />
<br />
What should I be doing in my code?<br />
<br />
THANKS!<br />

crop CImage bitmap to new Cimage
