Hello All,

my program allows users to organize products in a retail shelfs, and print it out.

Here is my big problem:
There are 1000+ products in one shelf, and each of them has photo with it.I use stretchBlt to scale the orginal photo dimension (e.g. 50x100) to (10x20) and put those photo to the CDC (for printing).

Photos are saved as jpeg, less then 200kb each. if i need to print a layout, which will send 1000x0.2M = 200MB to the printer. but most of the time the printer do not have enough memory to print.

I sort of come up with two solution, but dont know which one is better.

first, instead of using stretchBlt to resize only the photo size, write a funciton to resize the photo size and the file size. then load it onto the printing CDC.

the other option is to do a 'print screen'. only problem is layouts are bigger than the screen display size, so it will not print the entire layout. users need to crop out all other window's stuff, such as tool bar, task bar, start menu, etc. before sent to the printer. it also adds workload on users.

Is there any source code that can send the entire CDocument's content as an optimized image to the printer?

Thank you in advance
