画像のフォーマットを変換します。
- 引数
-
dst 変換後画像の格納先(numeric型、sizeof(float) * dst_width * dst_height * チャンネル数(解説参照)以上のサイズを確保すること) dst_width 変換後画像の横幅 dst_height 変換後画像の高さ dst_format 変換後画像の形式 (AILIA_NETWORK_IMAGE_FORMAT_*) dst_channel 変換後画像のチャンネル順 (AILIA_NETWORK_IMAGE_CHANNEL_*) dst_range 変換後画像のレンジ (AILIA_NETWORK_IMAGE_RANGE_*) src 変換元画像の格納先(32bpp) src_stride 変換元画像のラインバイト数 src_width 変換元画像の横幅 src_height 変換元画像の高さ src_format 変換元画像の形式 (AILIA_IMAGE_FORMAT_*)
- 戻り値
- 成功した場合は AILIA_STATUS_SUCCESS 、そうでなければエラーコードを返す。
画像フォーマットを変更します。dst_formatが AILIA_NETWORK_IMAGE_FORMAT_BGR もしくはAILIA_NETWORK_IMAGE_FORMAT_RGB の場合、チャンネル数は3, AILIA_NETWORK_IMAGE_FORMAT_GRAY の場合チャンネル数は1となります。
