Rectangle as bitmap

[nageswaragunupudi]

Hi.

There is a dialog box with brush. I need to select a certain rectangle on this window and save it to a file as a bitmap. How to do it ?

If it is a large dialog with a brush I can provide solution.
But I doubt if it is an Activex control

[Natter]

Sorry, I didn't understand

[Antonio Linares]

Is the activex showing the same image all the time or does it change like a map ?

[Natter]

This is a map. I want to print large formats A1, A0

[Antonio Linares]

I think that you can only get an image of what it is shown on the screen, unless the activex provides a method to do it.

What activex is it ?

Please build and run c:\FWH\samples\olebrow.prg and look for the activex and inspect the methods that it provides or
check the documentation about it

[Natter]

This is IE. I work through it with the Maps API. There is no means for printing or output to a file in this API

[Antonio Linares]

Could you provide us a small and self contained Prg to test here ?

I'll try to make an example, but it's difficult. Can use IE features ? This browser has both Print and Save As, however, I do not know how to address them

I tried using "Shell.Explorer.2" Activex.

For me oActivex:Print() is working. I do not have large printer, but it printed the google map on my A4 size paper.
You may try with Large paper printer and with a few trials and errors you may be able to print.

[Natter]

I checked o Activex:Print(). Anyway, only the screen is printed.
Please give your example with oActivex:Print() and google map. Based on it, I will make a small example showing my problem

[Natter]

Could you provide us a small and self contained Prg to test here ?

In this example, I increase the size of the ActiveX according to the selected print format.
1. Download the Google Map
2. Select the format (size)
3. Print (to file)

Good. Is it working for you now?

In this version, we can print the map or save it as a pdf file. Is it possible to save the map as a bitmap file ?
