simGetScaledImage

Generates a scaled-up or scaled down version of the input image

C++ synopsis

unsigned char* simGetScaledImage(const unsigned char* imageIn, const int* resolutionIn, const int* resolutionOut, int options, void* reserved)

Arguments

• imageIn: pointer to rgb or rgba values of the input image.
• resolutionIn: resolution of the input image.
• resolutionOut: desired resolution of the output image. The values will be replaced by the effective resolution of the output image
• options: bit-coded:
  • bit0 set (1): the input image is rgba, otherwise it is rgb
  • bit1 set (2): the returned image is rgba, otherwise it is rgb
  • bit2-3: 0:ignore aspect ratio, 4:keep aspect ratio (the effective resolution of the returned image will be different), 8:keep aspect ratio by expanding (the effective resolution of the returned image will be different)
  • bit4 set (16): no smooth transformation
• reserved: Reserved for future extension. Set to nullptr.

Return

• nullptr if operation was not successful, otherwise a buffer containing the output image data. The user is in charge of releasing the buffer with simReleaseBuffer.
