i want to learn something abot loading images (above formats).
I want to load them *w*i*t*h*o*u*t* using libs like PicoPng or something like that.
The Image i load should be used as an backgroundimage (1024x768) not as a small texture(256x256)!
I tried to find tutos, but there is nothing exept the ... use PicoPng.lib etc. versions Dead | X|

Why "reinvent the wheel" when you can use a library? Confused | :confused:

I don't know about tutorials, but it generally comes
down to looking up the published file format and parsing the
file appropriately.

Examples:
BMP[^]
PNG[^]
TGA[^]
RAW = Google "RAW file format"...there's lots of raw formats.

or when one can't figure out one needs to do that, perhaps one should start by reading the McDonalds menu. Beer | [beer]

You can also use GDI+ for loading images. Here are some examples:

http://www.codeproject.com/KB/cpp/GDI_.aspx[^]

If you don't want to use GDI+, than you can try CxImage library:

http://www.codeproject.com/KB/graphics/cximage.aspx[^]

It's really very cool library that can help you to get information about loading images.

For bmp,png,gif,jpeg and I think tiff you can use of CImage class But onthe codeproject you can see CXImage article is very helpful for you.

By Using Mapping modes how to draw points in a rectangle?

Hi,
I am having a rectangle.
I need to create a graph by setting x axis -80 to 80 and y axis -80 to 80.
Means the BottomLeft of the rectangle will be (-80,-80); and top will be (80,80).
By using mapping modes MM_ANISTROPIC.
I need to draw a point if suppose a point is (-75,60).
Then the point should be drawn in the rectangle.

Thanks in advance.

No I won't. Now what are going to do?

Sure no problem. Think first then write code then observe the results. Now repeat as many times as necessary.

Convert CString to char*

I'm trying to find an easy way to convert a CString to a char* without having to do it character-by-character.

I've tried memcpy unsuccessfully. Anyone have any tricks?

CString provides a (LPCTSTR) cast operator for this.BTW, what are you trying to achieve ?

can't you just use CString::operator[]() or CString::GetAt() to retrieve a character in the CString object ?

I want to get the entire string into a char array in case I can't figure out how to do something else.
