fg_getmaxx()
|
Returns the maximum x coordinate in screen space for the active virtual buffer.
|
|
fg_getmaxy()
|
Returns the maximum y coordinate in screen space for the active virtual buffer.
|
|
fg_getview()
|
Returns the current viewport limits and their screen space equivalents, as defined in the most recent call to fg_setview().
|
|
fg_getworld()
|
Returns the current world space limits, as defined in the most recent call to fg_setworld().
|
|
fg_initw()
|
Initializes Fastgraph's internal world space parameters. This function must be called once, before any other function that uses world coordinates.
|
|
fg_setdc()
|
Establishes the device context for the window's client area.
|
|
fg_setview()
|
Defines a 2D viewport with the specified extremes at the specified screen space position.
|
|
fg_setworld()
|
Defines the 2D world space coordinates that correspond to the physical edges of the active virtual buffer.
|
|
fg_vballoc()
|
Creates a virtual buffer of the specified size. The memory for the virtual buffer is allocated automatically.
|
|
fg_vbclose()
|
Closes the active virtual buffer.
|
|
fg_vbfin()
|
Terminates virtual buffer processing. This is typically the last Fastgraph function called in a program.
|
|
fg_vbfree()
|
Releases a virtual buffer's handle and frees the memory allocated to the virtual buffer.
|
|
fg_vbinit()
|
Initializes Fastgraph's virtual buffer environment. This function must be called once, before any other functions that reference virtual buffers.
|
|
fg_vbopen()
|
Makes an existing virtual buffer the active virtual buffer.
|
|
fg_vbpaste()
|
Copies a rectangular region from the active virtual buffer to the client area.
|
|
fg_vbscale()
|
Copies a rectangular region from the active virtual buffer to the client area, with scaling.
|
|
fg_xclient()
|
Converts a virtual buffer screen space x coordinate to its client area screen space equivalent.
|
|
fg_xscreen()
|
Converts a world space x coordinate to its screen space equivalent.
|
|
fg_xvb()
|
Converts a client area screen space x coordinate to its virtual buffer screen space equivalent.
|
|
fg_xview()
|
Converts a viewport x coordinate to its screen space equivalent.
|
|
fg_xworld()
|
Converts a screen space x coordinate to its world space equivalent.
|
|
fg_yclient()
|
Converts a virtual buffer screen space y coordinate to its client area screen space equivalent.
|
|
fg_yscreen()
|
Converts a world space y coordinate to its screen space equivalent.
|
|
fg_yvb()
|
Converts a client area screen space y coordinate to its virtual buffer screen space equivalent.
|
|
fg_yview()
|
Converts a viewport y coordinate to its screen space equivalent.
|
|
fg_yworld()
|
Converts a screen space y coordinate to its world space equivalent.
