Reallocation is not only + needed when dimendions and margins change, but also when the color depth + changes. Fixes bugs #691029 and #691108. + - Fixed arrayoption() macro in cups_put_params() function. Array values did + not get actually set in cups.header data structure. Bug only showed via + a compiler warning. + - Silenced compiler warning by presetting c0..c3 in cups_map_cmyk() to zero. + +git-svn-id: http://svn.ghostscript.com/ghostscript/trunk/gs@10890 a1074d23-0009-0410-80fe-cf8c14f379e6 +--- + cups/gdevcups.c | 32 +++++++++++++++++++++++--------- + 1 files changed, 23 insertions(+), 9 deletions(-) + +diff --git a/cups/gdevcups.c b/cups/gdevcups.c +index 551b806..4000abf 100644 +--- a/cups/gdevcups.c ++++ b/cups/gdevcups.c +@@ -975,7 +975,8 @@ cups_map_cmyk(gx_device *pdev, /* I - Device info */ + frac k, /* I - Black value */ + frac *out) /* O - Device colors */ + { +- int c0, c1, c2, c3; /* Temporary color values */ ++ int c0 = 0, c1 = 0, ++ c2 = 0, c3 = 0; /* Temporary color values */ + float rr, rg, rb, /* Real RGB colors */ + ciex, ciey, ciez, /* CIE XYZ colors */ + ciey_yn, /* Normalized luminance */ +@@ -2703,9 +2704,13 @@ cups_put_params(gx_device *pdev, /* I - Device info */ + int color_set; /* Were the color attrs set? */ + gdev_prn_space_params sp; /* Space parameter data */ + int width, /* New width of page */ +- height; /* New height of page */ ++ height, /* New height of page */ ++ colorspace, /* New color space */ ++ bitspercolor; /* New bits per color */ + static int width_old = 0, /* Previous width */ +- height_old = 0; /* Previous height */ ++ height_old = 0, /* Previous height */ ++ colorspace_old = 0,/* Previous color space */ ++ bitspercolor_old = 0;/* Previous bits per color */ + ppd_attr_t *backside = NULL, + *backsiderequiresflippedmargins = NULL; + float swap; +@@ -2800,9 +2805,10 @@ cups_put_params(gx_device *pdev, /* I - Device info */ + else if (code == 0) \ + { \ + dprintf1("DEBUG: Setting %s to", sname); \ +- for (i = 0; i < count; i ++) \ +- dprintf1(" %d", (unsigned)(arrayval.data[i])); \ +- cups->header.name[i] = (unsigned)arrayval.data[i]; \ ++ for (i = 0; i < count; i ++) { \ ++ dprintf1(" %d", (unsigned)(arrayval.data[i])); \ ++ cups->header.name[i] = (unsigned)(arrayval.data[i]); \ ++ } \ + dprintf("...\n"); \ + } + +@@ -3243,23 +3249,31 @@ cups_put_params(gx_device *pdev, /* I - Device info */ + } + #endif /* CUPS_RASTER_SYNCv1 */ + ++ colorspace = cups->header.cupsColorSpace; ++ bitspercolor = cups->header.cupsBitsPerColor; ++ + /* + * Don't reallocate memory unless the device has been opened... + * Also reallocate only if the size has actually changed... + */ + +- if (pdev->is_open && (width != width_old || height != height_old)) ++ if (pdev->is_open && ++ (width != width_old || height != height_old || ++ colorspace != colorspace_old || bitspercolor != bitspercolor_old)) + { + + width_old = width; + height_old = height; ++ colorspace_old = colorspace; ++ bitspercolor_old = bitspercolor; + + /* + * Device is open and size has changed, so reallocate... + */ + +- dprintf4("DEBUG2: Reallocating memory, [%.0f %.0f] = %dx%d pixels...\n", +- pdev->MediaSize[0], pdev->MediaSize[1], width, height); ++ dprintf6("DEBUG2: Reallocating memory, [%.0f %.0f] = %dx%d pixels, color space: %d, bits per color: %d...\n", ++ pdev->MediaSize[0], pdev->MediaSize[1], width, height, ++ colorspace, bitspercolor); + + sp = ((gx_device_printer *)pdev)->space_params; + +-- +1.6.6.1 + |
