2000 Bug Fixes

Bug fixes are followed by the version number in which they are included and release date (as available).

ED Drawing on 10-, 12-, 16-bit grayscale images -- current foreground is white, but paintbrush and pencil draw black.
PRT Printer device name init for routing.
ED 16-bit grayscale images display darker on Pseudocolor (gamma problem?).

FIXED in 5.0-001 (08/16/96)

ED Pseudocolor visual -- brought up Color Picker -- had to click S/B, then click H again to get display data in 1D image area.
VW Converting Targa to XPM fails with console message "Bits/sample must be 1 for Group 3/4 encoding/decoding".
VW 256-level grayscale TGA files display as grayscale but report as line art.
ED With the selection tools, when selecting a row, you can move the selection area up as far as the top of the image and back down to the original starting point. Likewise, with columns, you can move to the left, but right only as far as the starting point. In each case, the selected row or column is the one in which the cursor started.
ENG The togray function didn't work from most image conversions (30-bit RGB, 36-bit RGB, 48-bit RGB, 32-bit CMYK, 64-bit CMYK, 16-bit gray), and doesn't work for togray 16 for a few (256-level gray, line art, 24-bit color, 256-color).
VW Open directory doesn't work if images don't have thumbnail file.
ENG Rotate has background problems for 36-bit RGB, 48-bit RGB, 32-bit CMYK, and 64-bit CMYK.
ENG Converting a 256-color image to xwd resulted in 256-level grayscale garbage.
ENG Converting a line art TIFF image with topseudo resulted in a 256-level grayscale image.
PRT Print function does not work correctly with selection areas. The non-selected area in the mask is uninitialized.
PRT Switching Print to landscape mode subsequently forces image to upper left hand corner of image (no longer moveable by user).
EDT Text stuff did not draw properly on new image types (e.g., 48-bit RGB).
EDT CMYK Blur/Sharpen tool didn't work correctly.
EDT Rotating image types -- 30/36/48-bit RGB and 32/64-bit CMYK -- Expanded (background) areas were not filled properly.
VW TIFF load sets the TIFF gamma to the gamma of the last loaded TIFF file. If the last loaded file has a gamma != TiffGamma, then subsequently saved images are stored with (gamma) instead of TiffGamma (desired behavior).
VW Switching to background mode or dragging cursor in color selection area while in background mode doesn't update color text values on color picker.
VW Modifications to CMYK text values are never "recognized" for color picker.
EDT Invert doesn't work on CMYK image -- image turns black.
SCN UMAX UC1200SE doesn't scan line art or grayscale.
EDT RGB<->CMYK functions not implemented.
PRN Switching Print from landscape mode to portrait causes an internal error.
INB Route printer selection is ineffective.
INB Setting preferences to Route to Inbox and Open Image conflict.
INB Stamp files that are placed in the monitored directory (when as image is saved, for example) are reported as new images in the Inbox and show up in the list.
ED Select the rectangular selection tool. Double-click it to set options. Change to elliptical and click OK. The icon displays a rectangle in white. It should be a green ellipse.
ENG Saving a line art TIFF image as BMP converted it to 256-color.
PRN Scaling images in the Print window causes them not to print.
SCN PowerLook 2000 shows 36-bit color instead of 12-bit gray in Image Type Selection button.
SCN Edit the Gang Scan list. Select Delete All. Edit the list again. (Shouldn't be able to.) Deleting an item will cause crash.
SCN Deleting the only remaining item in the Gang Scan List doesn't make the Edit List insensitive; then the same problem as in c537 occurs.
ED Pixel Tracking CIE values don't look right (L=-903.26?).
PRN Selected areas do not print.
PRN Multi-page images print the first page only.
FTP No error message is displayed when ftp login fails between some systems (ex: SGI to SunOS). Cancel and OK work, but the program doesn't give you any clue as to what it's waiting for.
SCN 256-color scanning support shows up as a selectable item on scan dialog on all scanners that support color, even though 256-color scanning is only supported on a subset of color scan devices (UMAX and HP by time of release).
VW Cannot save/load preference settings for color space conversions.
VW Platform-specific integration functionality not implemented.
PRN HP Color LaserJet printer support/verification, other HP Printer support/verification.
SCN When editing the Gang Scan list, you can scroll through the list a few times. Some of the entries will change to exact duplicates of the previous entry. Then they are scanned with this incorrect information.
SCN After adding areas to the gang scan, change the parameters. Then select Edit List. The dialog claims this is area 1 of X, but the display doesn't reflect the parameters until you scroll through the list.
ED Color select/report button does not show correct foreground and background colors.
PRN 256-color images do not print.
PRN 16-level grayscale images print a double-image. Depending on resolution, the image may be slanted.
PRN 64 CMYK, 30-bit color, 36-bit color, 48-bit color images print with mottled colors.
PRN 16-bit grayscale images print a blank page.
ED Selecting a circular region is constrained by the zoom ratio. If zoom is at 1:2, the selected circular region can be up to 1/2 the image width. At 1:3, the selected region can be up to 2/3 the image width.

FIXED in 5.0-002 (9/15/96)
