Hi,
I have to modify some patches made by another person.
In one of them, [pix_write] is used to save screenshots of the image being shown in the gemwin.
However, the user would like to be able to save a higher quality image, namely 2000x2000 (so it can be printed). To my knowledge (and to the knowledge of the person who made the patch), the only way to do this is to increase the resolution of the gemwin. But since the resolution of the screen cannot be increased so much, the complete image cannot be seen. The user wants to be able to still see the whole image (at its usual resolution of 480x480) while saving screenshots at a higher resolution.
So the question is: is it possible to save an image which is not the one being rendered into the gemwin? So that I can for example generate a big image, save it, reduce its size, and render the reduced image instead of the big one?
A slow-down due to great cpu consumption at the moment of "capturing" the image would be acceptable (though not desired, obviously) provided that it is limited to the moments when the image is captured.
Any idea?
P.S.: The image is being generared by "tiling" the image from a camera, i.e. repeating it: that's why it make sense to save the resulting image in a higher resolution: if the camera has for example a res of 640x480 and it is being repeated in a 5x5 grid, up to 3200x2400 resolution "makes sense" for the saved image.
Thank you very much m.
