Grafiken in WordPress: SVG, SWF, ODG, VSD, PPT

Auch in WordPress-Artikeln und -Seiten möchte man ja ab und zu auch schöne Vektorgrafiken einbauen – nicht nur Pixel-Bilder.

Je nach Format (SVG, SWF, ODG, VSD, PPT,…) sind da unterschiedliche Lösungen möglich, wo bei schon das Upload solcher Grafiken ein Problemchen sein kann.

SVG Graphics

Eine SVG-Grafik kann einfach über im IMG-Tag in HTML eingebunden werden. In WordPress wird das wie folgt unterstützt.

SVG Upload

SVG upload not allowed?? (9 posts)

  1. I’m trying to put an SVG image into a post, but I can’t upload it.

    “Harajuku map.svgz” has failed to upload due to an error
    Sorry, this file type is not permitted for security reasons.

    What gives?! It’s just an image!

  2. You can overcome the security warning by adding this to your current themes functions.php file.

    add_filter('upload_mimes', 'custom_upload_mimes');
    
    function custom_upload_mimes ( $existing_mimes=array() ) {
    
    	// add the file extension to the array
    
    	$existing_mimes['svg'] = 'mime/type';
    
            // call the modified list of extensions
    
    	return $existing_mimes;
    
    }

    Then you should be able to upload files with an .svg extension

Computer: How I Rooted my Acer Iconia A500

My Dedication to the Android Tablet “Acer Iconia Tab A500”

Last year I bought the tablet Acer Iconia Tab A500 with Android 3.0 (“Honeycomb”) preinstalled.

When I started up the A500, it immediately updated to Android 3.2.1.

I was quite staisfied with this 10″ tablet, I loved especially:

  • the fast processor
  • the nice display which reacts very fast and precisly to the finger guestures
  • the fully-blown USB host

The major weak point in my judgement is:

  • Can not be recharged via USB (but I found a car charger finally, that is kind of half of the solution)

Decision to flash the A500 ROM

My decision now not to treat my Acer A500 tablet as a professional working platform, but only as a kind of “toy” was influenced by:

  • Acer did announce to deliver upgrades to Android 4.0 (Ice Cream Sandwch = ICS) for April 27, 2012 but nothing happeded util now (26. May 2012)
  • Relevant Apps on the A500 requrie the device to be “rooted” (Titanium Backup, ClockSync, Cisco Any Connect)
  • My colleagues more and more are using iPads

So i now give to the A500 the status of beeing a “toy” while planning to move to the iPad some time during the year.

How I flashed the A500

The steps:

  • Honeycomb 3.2.1 (jargon: “HC3.2.1”) is not rootable
  • So we have to go back to an older Android version: 3.0.1
  • We have to download a appropiate ROM image, ……
  • Then install that older Android version (jargon: “flash the ROM” ) using the normal (jargon: “stock”) ROM update procedure (Recovery Mode) ……
  • Root that Android 3.0.1 with a tool named Iconiaroot-1.3.apk
  • Install CWM (= ClockworkMod Manager) which replaces the “normal” (jargon: “stock”) recovery procedures with more options. This requires a “rooted” Android version….
  • Decide which alternative Android ROM image you want to installl (jargon: “flash”)
  • Download that ROM image of choice
  • Install that ROM image (jargon: flash) by using CWM

In detail

General weblinks:

Downgrade your Android to version 3.0.1

  • Download file “downgrade_not_stable.zip” from http://netload.in/dateiExhRzE8Tbs.htm
  • Unzip and put file “update.zip” on the external micro SD-card of the Acer Iconia Tab A500
  • Power down the Acer A500
  • Power up the Acer A500 into it’s normal Upgrade Mode (Recovery Mode) i.e. you must hold the “Volume Down” key while pressing the power button. This will “Upgrade” (jargon: “flash”) the system ROM with the file “update.zip” on the external Micro SD.card

Root your Android 3.0.1

Install CWM

  • CWM stands for “ClockworkMod Manager”
  • CWM extends the actions you can perform in Recovery Mode
  • Download file ww-9.2.1.11-CWM-full-rooted.zip from: http://tegraowners.com/?cat=7
  • Install
  • use….

Chose a ROM, that you want to install (jargon: Flash that ROM) on the Acer A500

  • Thor A500 ROM V14.2
  • Download the ROM from http://tegraowners.com/?p=1272
  • Put the ROM on the external Micro SD Card of the A500
  • Reboot the A500 into Recovery mode (CWM)
  • in CWM:
    • Wipe data / factory reset
    • Wipe cache partition
    • Advanced –> Wipe Dalvik cache (Java Virtual Machine)
    • Intsall ZIP from SD Card
    • Select the ZIP file for flashing
    • …..

Jargon

  • ICS = Ice Cream Sandwich (Android 4.0)
  • HC = Honeycomb  (Android 3.2.6)
  • CWM = ClockworkMod
  • Stock = the “normal” things delivered with a device by the manufacturer / vendor

The Image “Thor A500 ROM V14.2”

List of A500 ROMs: http://forum.tegraowners.com/viewforum.php?f=9

  • Is “rooted” so we can install all the apps that require root access rights, like Titanium Backup,…
  • Is Android 3.2.1 with pieces from ASUS
  • Tapping on “Recent Apps” produces a screen shot
  • “Quick Controls” can be enabled and disabled through the settings dialogue
  • ASUS battery icon (small and showing the charging percentage)
  • App QuickBoot is included
  • App AmazonKindle is included
  • App DriveMount is included
  • You can overclock and underclock the CPU
  • usb_huawei_3g patch: http://www.mediafire.com/?ahayl9c9586z4p9

Observations with this ROM:

  • Mount point for the removable Micro SD card is not /mnt/external_sd but /Removable/MicroSD
  • Mount point for the USB-drive is not /mnt/usbdrive but /Removable/USBdisk1

 

The image “Tegraowners ICS ROM v164 (thor & digetx)”

After that successful experience with flashing my A500 with the image “Thor A500 ROM v14”, I tried the next step….

Steps to flash the A500 ROM with is image: Same procedure as described above

Results:

  • My A500 now runns with a rooted Android 4.0.4 (ICS = Ice Cream Sandwich) very smoothly.
  • Since I wipped as recommended, I had to re-install all my apps.
  • To start that install thing I hab first to install the “Google Market Place”, how called “Google Play”. I found that in the download: …..

Applications

  • Titanium Backup now runs perfectly (required root access)
  • ClockSync now works perfectly (required root access)
  • Google Chrome Browser (required Android 4 – ICS)

Next thing to try:: HUAWEI 3G USB WebStick……

VektorGrafik (aus Wiki)

Contents

Wieder einmal fragte ich mich, in welchem Format und mit welchem Tool ich eigentlich Vektorgrafiken machen will/sollte, die ich viele, viele Jahre benutzen will.

 Formate

 SVG

Zuerst versuchte ich selbstverständlich SVG da dies als “offener” W3C-Standard am interessantesten schien.

Die SVG-Tools erschienen mir aber nicht sehr stabil.
Interessant war der SVG Bezier Animator namens beez (http://beez.sourceforge.net).
Auch das Tool SodiPodi 0.32 (http://sourceforge.net/projects/sodipodi/) war interessant, aber noch nicht richtig ausgereift.
Einzig Adobe Illustrator 10 ist sicher stabil, kostet aber richtig und gefiel mir eigentlich nicht bezüglich der Speicherung im SVG-Format – das war sehr proprietär (Adobe)…

Sodopodi wird nicht mehr weiterentwicklt. Eine erfolgreiche Abspaltung (sog. “Fork”) von Sodopodi ist Inkscape
Microsoft: PowerPoint oder Visio Wenn einem gar nichts solides schönes zu Vektorgrafiken einfällt, kann man sicher Microsoft PowerPoint oder auch Microsoft Visio nehmen.

 Flash

Aber Flash (SWF) ist ja auch noch ein schönes Format. Das FLA-Format ist zwar proprietär (Macromedia, Adobe), das SWF-Format aber OPEN. Als Tool gibt es Macromedia Flash: das ist teuer und kompliziert. Da habe ich das sehr verbreitete Tool SWiSH ausprobiert und muss sagen: OK das probiere ich mal ein paar Wochen als Testphase aus.

Für WordPress gibt es ein Plugin names "Easy Flash Embed" damit kann man SWF-Dateien ganz einfach in WordPress-Artikel einbinden:
