Nonetheless, the main controller is not - * trivial. Its responsibility is to provide context rows for upsampling/ - * rescaling, and doing this in an efficient fashion is a bit tricky. - * - * Postprocessor input data is counted in "row groups". A row group - * is defined to be (v_samp_factor * DCT_scaled_size / min_DCT_scaled_size) - * sample rows of each component. (We require DCT_scaled_size values to be - * chosen such that these numbers are integers. In practice DCT_scaled_size - * values will likely be powers of two, so we actually have the stronger - * condition that DCT_scaled_size / min_DCT_scaled_size is an integer.) - * Upsampling will typically produce max_v_samp_factor pixel rows from each - * row group (times any additional scale factor that the upsampler is - * applying). - * - * The coefficient controller will deliver data to us one iMCU row at a time; - * each iMCU row contains v_samp_factor * DCT_scaled_size sample rows, or - * exactly min_DCT_scaled_size row groups. (This amount of data corresponds - * to one row of MCUs when the image is fully interleaved.) Note that the - * number of sample rows varies across components, but the number of row - * groups does not. Some garbage sample rows may be included in the last iMCU - * row at the bottom of the image. - * - * Depending on the vertical scaling algorithm used, the upsampler may need - * access to the sample row(s) above and below its current input row group. - * The upsampler is required to set need_context_rows TRUE at global selection - * time if so. When need_context_rows is FALSE, this controller can simply - * obtain one iMCU row at a time from the coefficient controller and dole it - * out as row groups to the postprocessor. - * - * When need_context_rows is TRUE, this controller guarantees that the buffer - * passed to postprocessing contains at least one row group's worth of samples - * above and below the row group(s) being processed. Note that the context - * rows "above" the first passed row group appear at negative row offsets in - * the passed buffer. At the top and bottom of the image, the required - * context rows are manufactured by duplicating the first or last real sample - * row; this avoids having special cases in the upsampling inner loops. - * - * The amount of context is fixed at one row group just because that's a - * convenient number for this controller to work with. The existing - * upsamplers really only need one sample row of context. An upsampler - * supporting arbitrary output rescaling might wish for more than one row - * group of context when shrinking the image; tough, we don't handle that. - * (This is justified by the assumption that downsizing will be handled mostly - * by adjusting the DCT_scaled_size values, so that the actual scale factor at - * the upsample step needn't be much less than one.) - * - * To provide the desired context, we have to retain the last two row groups - * of one iMCU row while reading in the next iMCU row. (The last row group - * can't be processed until we have another row group for its below-context, - * and so we have to save the next-to-last group too for its above-context.) - * We could do this most simply by copying data around in our buffer, but - * that'd be very slow. We can avoid copying any data by creating a rather - * strange pointer structure. Here's how it works. We allocate a workspace - * consisting of M+2 row groups (where M = min_DCT_scaled_size is the number - * of row groups per iMCU row). We create two sets of redundant pointers to - * the workspace. Labeling the physical row groups 0 to M+1, the synthesized - * pointer lists look like this: - * M+1 M-1 - * master pointer --> 0 master pointer --> 0 - * 1 1 - * ... ... - * M-3 M-3 - * M-2 M - * M-1 M+1 - * M M-2 - * M+1 M-1 - * 0 0 - * We read alternate iMCU rows using each master pointer; thus the last two - * row groups of the previous iMCU row remain un-overwritten in the workspace. - * The pointer lists are set up so that the required context rows appear to - * be adjacent to the proper places when we pass the pointer lists to the - * upsampler. - * - * The above pictures describe the normal state of the pointer lists. - * At top and bottom of the image, we diddle the pointer lists to duplicate - * the first or last sample row as necessary (this is cheaper than copying - * sample rows around). - * - * This scheme breaks down if M < 2, ie, min_DCT_scaled_size is 1. In that - * situation each iMCU row provides only one row group so the buffering logic - * must be different (eg, we must read two iMCU rows before we can emit the - * first row group). For now, we simply do not support providing context - * rows when min_DCT_scaled_size is 1.

The intended implementation is that there is a strip buffer in - * memory (as high as is possible given the desired memory limit), plus a - * backing file that holds the rest of the array. - * - * The request_virt_array routines are told the total size of the image and - * the maximum number of rows that will be accessed at once. The in-memory - * buffer must be at least as large as the maxaccess value. - * - * The request routines create control blocks but not the in-memory buffers. - * That is postponed until realize_virt_arrays is called. At that time the - * total amount of space needed is known (approximately, anyway), so free - * memory can be divided up fairly. - * - * The access_virt_array routines are responsible for making a specific strip - * area accessible (after reading or writing the backing file, if necessary). - * Note that the access routines are told whether the caller intends to modify - * the accessed strip; during a read-only pass this saves having to rewrite - * data to disk. The access routines are also responsible for pre-zeroing - * any newly accessed rows, if pre-zeroing was requested. - * - * In current usage, the access requests are usually for nonoverlapping - * strips; that is, successive access start_row numbers differ by exactly - * num_rows = maxaccess. This means we can get good performance with simple - * buffer dump/reload logic, by making the in-memory buffer be a multiple - * of the access height; then there will never be accesses across bufferload - * boundaries.
