Hai All,
I have developed a Bitmap Driver based on Microsoft UniDrv Driver
sample provided in DDK.
Everything is fine with my driver except onething…
My driver basically stores the Bitmap in 24-bit DIB format.
I am using diffrenet Resolutions in my GPD like 75,100,150,300 qnd 600. Problem with my Driver is, It works fine with all lower resolutions such as 75,100 and 150…If I change my resolution settings to either 300 or 600 I am not able to store the entire Document…In case of 300 DPI only 1/4 size of the original Doc. and in 600 DPI It still reduces…
Can anybody suggest or helps me in this regard.
Thanks in advance
Vijji

Kindly do check if the size for 75,100,150 also changes or changes only
for 300 to 600, since the change in size may not be significant in
smaller
resolutions…If it changes, it inferences that, the change in resolution
is performing a scaling opertion…

Hai Shive,
Thank U for Ur immediate reply…
I am not catching Ur point here, R u talking abt created Bitmap Size?
If so…Sizes r varying depending on DPI selected…
How to manage scaling from my Driver…
I have to get the whole document image for all of my resolutions, How can I get it?
with regards
Vijji
