HPScan

HPscan v2.0 26 March 2025 Pete Brown Introduction ============ HPscan is a basic scanner frontend. HPscan builds the scanimage.exe command line based on the settings and selections made. Mode and Resolution options supported Preview image scan at low resolution Selection of an area of the Preview image for scanning supported Option to open scan in a Viewer Application No, HPscan does not perform any image correction or enhancement; this is left to whatever graphics editing program you use. Originally designed for HP scanners that use the hplip and hpaio libraries HPscan can also be used with any scanner that uses a sane ".conf" file - later model scanners that cannot be used with TAME/2 because they have no entry in the TAME/2 scanner database should work with HPscan. V2 Updates March 2025 ========================= Interface changed from V1 (which used a Tabbed Notebook) Added a Settings button to open the Settings page Added code to "automate" completion of scanimage.exe, nconvert.exe and URI for hpaio connected scanners - well, you still have to click in the entryfield Options moved (from Setting tab in V1) to dropdown Menu items on main form Added the option Parameters; when Checked this displays a message showing the scan parameters with the option to Cancel the scan Preview image can be displayed in a choice of sizes:- 430 x 592 dpi 538 x 740 dpi 645 x 888 dpi Recoded image area selection to scan selected (crop) area more accurately Add TIFF and PNG options to File Save As... dialog Add code to ensure filename extension and file type match Recode scanimage command line to use "--format=" to specify file type pnm/tiff/png/jpeg "--output-file=" to save scan to specified file Store last used File, Save As... Path for next use Store last used File Type for next use Installation: ============= HPscanV200.zip contains the following files: HPscan.exe - the executable file HPscan.hlp - application Help file HPscan.txt - this readme file HPscanS.bmp - bitmap displayed when HPscan starts set to Preview image size 430 x 592 HPscanM.bmp - bitmap displayed when HPscan starts set to Preview image size 538 x 740 HPscanL.bmp - bitmap displayed when HPscan starts set to Preview image size 645 x 888 HPscan.cmd - creates a HPscan Desktop folder and program objects Unzip HPscan.zip retaining directory structure to a drive:\directory of your choice, eg G:\PROGRAMS\HPscan Run HPscan.cmd to create a Desktop program object for HPscan.exe HPscanV200.wpi contains the above files with the exception of HPscan.cmd and is installed by doubleclicking the HPscanV200.wpi file to start the Warpin Installer. *After* checking the below Requirements start HPscan and complete the required Settings. Instructions on Setup and Use are in the HPscan Help file. Requirements: ============= An installed and working scanimage.exe (sane ) The application nconvert.exe is required as it is used to resize and convert the Preview scan from PNG to BMP; download from http://download.xnview.com/NConvert-os2.zip Unzip nconvert.zip retaining the directory structure to a drive:\directory of your choice, eg G:\PROGRAMS\NConvert Problems ======== Given the below described testing system configuration (see 'Testing System Configuration' section below) it has been noted that while initating the Scan action the WPS may for a short period of time become unresponsive to user inputs. Specifically: - switching to any window NOT currently showing in the active XPager virtual Desktop will not work - attempting to use ALT-TAB combination to Task Switch will not work - attempting to use lSwitcher taskbar (by moving the cursor to taskbar activation area) will not work This is especially prevalent while scanning at higher resolutions. This may affect some systems more than others. If you are seeing such symptoms on your system a possible workaround is to use either markexe.exe from the OS/2 Toolkit, or execmode.exe, in \OS2 directory, to mark HPscan as MPUNSAFE. 1) markexe.exe command to invoke: 'markexe mpunsafe hpscan.exe' 2) execmode.exe command to invoke: 'execmode -sp -v hpscan.exe' Testing System Configuration -------------------------- - OS/2 4.52 SMP (multi-core CPU) - SNAP video driver (ATI X850) - multi-head display monitor (two display panels) - XWorkplace XPager enabled (creating 9 virtual desktops) Thanks ====== to Dariusz for 1] Pushing me into updating HPscan and some suggestions on interface change 2] Doing lots of testing
